guys just got a ohc j.a.p 500 speedway motor for my hagon were can i buy parts
-
hi
do you realy have an ohc jap motor they are very rear and hard to get parts for.if you have a 5stud or 4b 4 stud or 84s parts come up from time to time on ebay most get there parts from uk
cheers
jim
-
i never knew they they made OHC, i thought they were all push rod engines, any chance of posting a pic?
-
hoony
the ohc is a double over head cam 4 valve hard to find and so are the pics of them if you whant 1 search 4v jap
-
The 4 valve JAP was a bit of a floperoo but is a tasty collector piece. I doubt I'd race one because of the parts problem. I know someone who'd probably be willing to swap a 2 or 4 valve Jawa for the JAP if you're interested K2000X
-
firko
if it were mine 10 jawa motors would not see it move from my garage.
hoony
there is a guy who races in our club days who has a hagon 84s and also a 4v dohc jap i will get some pics for you if he brings it along.
-
Thanks Jim.
I have a fondness for old speedway iron.
V twin 1000cc japs are a nice old unit as well.
-
when i used to road race (84s jap in a goldy frame) a guy call bob jolly (i think that was his name) from s.a had a vtwin jap in a manx frame.almost as good as eric deb vincent.
cheers

thats not a dohc 4v jap it still has push rods.the motor has a huge cam chain cover in polished alloy very pretty
cheers

yeah its a o.h.c jap she's ruff as guts but all there it had been sitting under a saw bench for a bloody long time. he had it in a some type of sprint car/ go kart thing with a norton box...i will have a look at some sites in england first. i havent pulled it apart yet 2 see what condition the inside is like
-
kx2000x
sent you a email with pics of 4v jap also to you hoony.
is this the 1 you have
-
They were still crap Jim. I'd rather have those 10 Jawas, at least you'd be 1: able to get parts and 2: be confident of finishing a meeting.
The reason they're rare is that most of them ended up as boat anchors or like John Titman used his for, as a door stop. We've got a mate who thought he was going to clean up big time selling his and asked serious money for it in the speedway magazines in the UK. He got no response whatsoever other than blokes calling him a thief for asking so much. Jonesy's got one of the best speedway engine collections in the world and he didn't even bother with our other mates 4v JAP. Having said that, he doesn't have one in the collection and he's hot to trot on a swap when K2000X finds that the parts situation makes the engine financially unviable. I know I'd rather have a Jawa that is not only faster, lighter and way more reliable but you can buy parts in K Mart (well...not really but you know what I mean). JAP dohc4v engines were too little, too late when compared to the Weslake and even the not so good 894 twin cam Jawa.
-
mark
i wasnt going to use it just polish all the alloy and there is a lot and sit and look at it.japs are too fragile and expencive to rebuild,they just look nice.with the pre 85 slider class now any upright will do 4v or 2v,if i could afford 1 i would have either a godden or gm my be the last 4v jawa long stroke upright with rec,oil pump and pvl ign as std
cheers
jim
-
yep jim its the same motor as the blue hagon...how can you tell year model for hagon frames
-
HI
its a 1978 dohc 4 valve jap.only made for 1 year
most engine parts i think are the same as 84s but dont know anything about the cam gear
-
cameron racing engines in uk make new parts there sending me price list and product list
-
in the olden days when i used to read any mag that had any thing about fast machinery the current gospel of the american hot rod mags was "if it won't go CHROME IT", so i'm with jim on this, but no need for chrome just polish it then put it in the lounge room. cheers wally.
-
I'm with you Jim, did a bloke named Tony Lacey win an Aussie title at Seymore on one? Dunno bout Firko's Jawa obsession, just cause it came from Europe don't mean it's the duck's guts.
-
G'day Pete, that would have been or 1979 or 80, I rode at that meeting myself on a KX 250 A5, didn't do any good. I didn't realize Tony was riding a 4V JAP though.
-
Yeah Curly I'm sure it was a 4-valver, not sure bout ohc I think they were pushrod operated, will check with Norris (79).I rode there as well (Hagon Yamaha)- Chris Watson won 250 (I think).Track was rough.
-
? Dunno bout Firko's Jawa obsession, just cause it came from Europe don't mean it's the duck's guts.
Not really a Jawa obsession Pete, I couldn't give a hoot either way. I'm just relating what most experts think of the 4v ohc JAP. The pushrod JAPs however were great old things. I'm pretty sure Lenny Norris used a 4b JAP and not a cammer but I'll cop it if I'm wrong.
As it is right now, I have more Japanese bikes in the collection than Euros. No bias either way from this old fella if that's what youre alluding to.
-
Thought I'd get your hackles up Mark. Len never used a 4-valve JAP but he has a good memory.Having owned 2 JAPs and a Jawa during the 70's, the JAP is my pick of the 2 motors on short circut.
-
Just a little note bout the JAP, got the info from Len Norris.Tony Lacey won the unlimited title in 79 @ Seymore using an 84C (factory 548cc JAP) with a Frazer tuned factory ohc top-end running a blue magnum carb, in Len's opinion it was just too late in the day for J.A. Preswick, Weslake already on the scene, but the mighty JAP still performed that day,Hurrah! Len's first JAP was an 84S short-stroke,his next one was a 4B long-stroke,quickly updated to 600cc for the unlimited class while he rode Kevin McDonald's bikes in the 500 class.They were the days, my last JAP (probably one of the last new one's sold in Aust. with electronic ign etc)got bored to 548 in an effort to keep the 4-valvers in sight, the weapon of the time had to be 588cc Weslake,they just gated so well.Good luck with the rebuild Hoony you probably have a piece of history there, its no boat anchor.
-
Len's opinion it was just too late in the day for J.A. Preswick
That's what I reckoned earlier. They were too little too late. Tony Laceys win would have been one of the few on a a global sense. The engine was built as a speedway motor and in that discipline they were way off the pace. Even though I've slammed the 4V JAP, I reckon it's a great collectors item and something unique for the occasional race or parade but I think K2000X wants a race bike not a show pony. The JAP would be a expensive to rebuild and maintain for a few skids at the vintage races. A 4B or 84s would be fine but a cammer? too rare and hard to find bits for. I still reckon that a Jawa, Godden or even a Wessy would be better both financially and on the track. It's kinda like my V12 Jag. They go OK, look and sound amazing but in the real world, a simple Chev V8 will usually whoop it every time for a fraction of the rebuild costs.

Speaking of JAPS...I heard from Mike Greenaway in Townsville who tells me he's building a Cheney with a Cooper JAP engine. Apparently the engine is an aluminium barrelled version of the 4b made by Cooper Racing Cars for their little formula 3 cars from the 50's. Now that's a rare JAP.
-
firko
is that brian martins 4v he got his from frazers
-
No idea Jim but the Kevin Fraser sticker might point it in that direction.
-
Not to be a pedant but I thought it was J.A.Prestwich.
I think I have a recolection that Fraze himself rode a 4V JAP right towards the end of his long and great career. Gus who, Firko?
I agree with Jim & Firko, straight to the pool room with this GEM.
-
keven did and thats the 1 brian m has got.he told me so as he was loading his newly bought dohc jawa in the boot of his car
jim
-
Gus who, Firko?
Gus Priem, you probably met him at the show'n'shine, he had the Royal Enfield trials bike next to your ugly Beeza.
-
H i people, Sorry to point out but that is not a genuine DOHC JAP it is a conversion buy a gentleman from Victoria Don Stafford who with the help of Niel Street built a couple, one of which Kevin rode a few times, if you look at cam boxes you can see the street conversion similarity, DOHC JAPS were totally different as I have one myself. Off the topic does anyone have a phone for Ray Dole. By the way Japs are no more expensive to run than a Jawa
-
Don't tell lies Mr Burkett you're not sorry at all but quietly enjoying being able to put us ignorant's in our place.
Where have you been mate I hope all is well?
By the way the Elstar project, along with a couple of others has been neglected due to work commitments and several health issues of late.
You would remember as well as anyone, did Kevin ride a 4V JAP, factory or conversion?
-
talking to the fossil the pic is of a gen 4 v jap.the don staffard engine was push rod. there is a guy that races at nepean has the same engine as in the pic.i have about 4 pics at home of 4v japs and they are all the same as the 1 pictured.fossil(a.garvey454) has the original sales brochure for 1 and will scan it when he finds it i will get it posted then

Great topic, now who is gunna pull a pic of the other conversion, I'm sure I saw it at Griffith one year-pushrod operated and rockers lubed with a grease nipple at the time (apparently to be oiled delivered later). Hoony if you want to see the 4-valver win another Aussie title let Norris put it in his Godden for the Griffith meeting in Sept. He may even help you put it together, Hoony-if he does it will stay that way ie in one piece. Let me know an I'll start workin on him, we love to see him have another ride.
-
Hey Pete , Now wouldn't that be a blast, # 79 on a JAP 4 Valve at the Nats !! as far as the other conversion , you're not thinking of Jim Crowhursts Kyokuto are you ?? Got a pic of that in the pits at Griffith , mid '70s.
-
He may even help you put it together, Hoony
I don't think Hoony's your man Pete...K2OOOX is the fella with the 4v JAP.
-
Thanks Mark not Hoony, K2000x I'm just trying to gee-up Norris, his last ride was '98 title's @ Griffith. Alan's right it would be a blast. Alan that Stafford thing you mentioned rings a bell, be nice to see a pic of it. The Kyokuto brand sounds like the dodgy generator I bought last year.
-
Peter I was talking to Jonesy earlier today and as well as a few other classes, he's a definite starter for the twins flat tracker class, my bike too but I don't think it's in the league of Jonesys Nourish 850 or your Yamaha. It'll be there though. Are the twins going to be pre '75 or Pre 85 regs? Sorry to hijack the JAP thread. It'd be good to see Lenny on board again. Is it a possibility?

Correct-a-mondo, i don't have a JAP engine. i just have a love for old Speedway Iron like DT500 Douglas, Rudge Jap, ESO, Jawa, Weslake, Godden, GM etc.

Kyokuto:
Jim Crowhurst ran the engine for the '72/ 73 or thereabouts season and I do have a photo somewhere of the driveside of the machine in the Griffith pits, in a Hagon Sandracer frame.

Hey Pete
Don't have a photo of the Don Stafford 4 Valve Jap engine, but somewhere in my old magazine collection there is a report on it and the grease nipples on the rocker shafts ring a bell , I will try to find it
I do have a photo of the Kyokuto engine and have been trying to post it today no go so have asked Firko to do it for me.
Don Stafford made the Alstar frames and I used one of his taper roller head bearing diamonds in my Elstar after wrecking it at Young

G'day Fossil, Allan or JAP454, your prang at Young wasn't the same one that involved a host if riders including Billy Mack and Vic Mctaggart with Vic breaking both his legs?
This thread has been very interesting and educational, hasn't it Ian :D ;D ;) :P
Hey Firko, I do remember Gus and what a nice bloke, my beeza made his bike look even better though.
C'mon Lenny, you can do it.

Naah , Steve, not that prang but I do have some footage of the BIIG first turn prang at Young involving Captain Rats and the Poms in 197? my prang involved me an another rider chasing Langy in a final , saw the Captain at Blayney in 08.

I'd love to see that footage as would Bill himself. He lost all his photos in a flood several years ago. I promised him to forward on anything I can find.

Here's some more shots of the DOHC 4V JAP sent by Gus. The internal shots are interesting. Perhaps Ian has one of those rare Don Stafford motors and didn't realise it. ;D All he needs is a Meirson and an SR60 and he'd have the Aussie speedway engine Holy Trinity!

Ok Mark, now i'm intrigued.
what is the history and story behind the SR60 speedway bike. and Aussie made Meirson.
i have never heard of them. i suspect SR stands for "Street Racing"
-
Firko, that last bike is obviously a later model, where does the ignition point come from? Great looking bike though and interesting that Sammy Miller is one of the bodies standing behind.
C'mon Ian, you are becoming conspicuous by your absence, you're amongst friends here, I look forward to your input.
-
Firko, I'll go blind if you keep putting photos like that 4V JAP Longtracker up !! bloody beautiful looking bit of kit !!
OK the Stafford/Street engine, I always thought the Stafford engine was pushrod so shows you how memory plays tricks on you !!
Question for anyone :- At Liverpool Speedway in 197?, I snuck into the pits and had a look at Phil Crump's Neil Street engine and, as I remember , the timing chain came off the engine sprocket carrier , is my memory correct on that one or not ??

The SR60 ( SR for Southern Racing-60 for the proposed horsepower goal) is the great Aussie project that died almost before it started. Adelaides Fred Jolly was the Jawa speedway agent for Australia. At some time in 1971/2 Jawa pulled his franchise and gave it to Frasers in Adelaide. In reply Jolly decided to make his own engine and got together with ? Clisby, a successful compressor manufacturer who'd recently designed a V6 F1 style engine. They made two complete bikes..the red one one pictured, #1 and a green bike #2 before her realised that the project wasn't going to be financially viable and the bikes hidden were away in a shed for the next 25 years. Eventually Jolly died and his assets were sold off. Number 1, the red bike was bought by Alan Jones and Number 2 went to an unknown collector in Perth along with all of the casting patterns. Number 2 was never started but Alans #1 bike has a total of 8 laps under its belt. Jolly had Jim Airey lined up to test the machine in a private session at Rowley Park Speedway but he didn't show. Fortunately Danish speedway great Ole Olsen was in town at the time so he was recruited to test the bike. Only 8 laps were completed before some now unknown minor problem brought the session to an end but that was enough for Ole who was reportedly astounded by the performance of the bike declaring it faster than anything he'd ever ridden. He offered to buy it and taker it back to Europe but Jolly refused. The bike was never ridden again to this day. Alan has plans to eventually fire her up and put some laps on it but won't even think of it until the engine is thoroughly checked over. I've had a good look at it and it's a beautifully made piece of gear.
The Meirson was developed in Northgate, Brisbane by an auto electrician named Meirs who had been producing replacement aluminium cases for JAP speedway engines. He raced TQ midgets with JAP power and developed a his own engine based on the JAP that eventually evolved into the Meirson twin cam 2v engine bearing little in common with the JAP in design. A small number of engines were produced and mainly used in TQ midgets although Sydney rider Dave Mills spent some time developing it for solo speedway. The engine proved to be bulletproof and very fast but unfortunately, Mr Meirs died and the project ended. Alans engine is new and has never been fired. He hopes to fit it to an Aussie made frame sometime in the future.
-
Great stuff , Firko, and top photos , all this because someone asked about parts for a 4V DOHC JAP !
Was it " Clarrie" Meirs ?? he fixed the magneto of me Triumph in Brissie in 1967
While we are talking about Aussie Speedway engines , what became of the " Hejisun" motor , Ithink that spelling is right, as I remember it was to be manufactured by Hector and Jim Sunderland, relatives of Wagga's Bob Sunderland and there was an article about it in the motorcycle press of the day, anything known about it ?? or any photos ??
Us Aussies are an ingenious lot , aren't we ?
And lets not even start on Sid Willis' double knocker desmo Velo !!

G'day Mark,
thanks for taking the time to enlighten me (and everyone else) on the SR60 and Meirson stories. its hard to imagine anyone taking on such a task these days. certainly an interesting peice of speedway and Aussie motorcycling history in general.
tell me, does Alan J have a DT500 douglas or rudge speedway engine in his collection ?
-
what a great read this topic has developed into! cheers wally.

No Alan none of that really early stuff but I doubt there's a Jawa conversion he doesn't own. How's a rare American Offenhauser bike solo engine grab you or a 4V Rickardson from Sweden. It's amazing just what he's got.
Below is Jonesys #1 of 4 made Weslake 4v twin cam 1000cc twin, shown in a Terry Mead made road race frame.

I have a soft spot for Wessy's ever since i saw Russell Bergmierer and Lester Trewin ride an 850cc twin Weslake MX Wasp Sidecar back in 79' at Wonthaggi ( Vic titles maybe) Russell used to over rev it in each gear and it was fine as it was an engine developed for UK grass tracks. that made such an impression on me at the time i have never forgotten it and started my love for Sidecars and Speedway engines.
Russell and Lester purchased a 500cc twin Weslake ( probably the only one ever in Australia) to compete (and win) the 1982 Aussie MX 500cc sidecar titles at ACUSA park in S.A. and i made the trip over to watch those titles sleeping at the track.
i Also remember Sth Aussie Barry Buckley riding an XV1100 V Twin Yamaha side car at that same event. This was also the same event that Ray Vandenburg stuffed his knee ending what was the start of a brilliant career.
for the life of me i cannot remember who won the following, can anyone fill in the gaps?
500cc solo ( Trevor Williams?)
250cc solo
125cc solo
Junior 125cc
1000cc Sidecar ( possibly Brian Stewart / Kim Demarte ?)

Here's a photo of the Meirson. It shows its JAP heritage but is a totally Aussie built item. I stated earlier that Alans engine (shown here) was brand new and unused but Alan informs me that it's seen action in a TQ midget. Also shown is the Rickson 4v from Sweden. They were made by Tony Rickardsons dad back in the early 70s but he sold off the rights to Briggo after a small number were made. The engine is shown as it was sent from Sweden, sitting in Alans new Monark GP replica motocrosser frame.

Hi Guys,This has been a great thread,Here is a bit more ! This article was in the west wyalong paper in August 25 1972. Kev Beasley worked at our local Honda dealership,I always dropped in on my way home from school ('72 I was 13yrs ) and I remember Kev getting ready for the short circuit meeting the following weekend.He had just fitted the latest speedway motor to his hagon and the local paper took a photo in the Showroom, of him with his "Clarrie Meirs - Meirson MAGNUM" . Kev is now living in Brisbane and still racing speedway in the local area. PS I think this is one of Clarrie's first conversions as it has a different top end and running a magneto where Allan's motor is quite different. Cheers Len

Hey Loop. (Godden79) are you going to bring the J.A.P. out of mothballs and throw a leg over it for the Classic Titles. ;)
-
Nah Grasy, the mothballs are too thick, it's still apart from when it was measured after the titles at Griffith in 98 ! Pretty slack eh. I'll just stick to watching you guys these days I think !!
-
C'mon Len, I'm not going to beat around the bush here but I'm with Grasy, the Classic Dirt Track scene needs the profile that your involvement would help generate. If it's a competitive bike your after then just say the word and I'm pretty sure someone will come forward with an offer you can't refuse.
No horse heads involved I promise.
The Golden years of Dirt Track are in my "Blood", as it is with you and having someone who has been there and done it, certainly adds plenty of weight.
I'm personally working on brother Carl and I know the competitive instinct goes deep, but as I've already said, we would all enjoy you're participation.
Steve.

G'day all
Lenny , It would be awesome for every body for you to come out an have a skid around , not wanting to put pressure on you , mind !!
Seriously, it would be a blast to see you out there, bloke , so I can go off on the microphone.
Ta for posting the the pix of the Hejisun, Lenny, now thats a rare one !!
What a thread this is and I think it's not over yet.
Steve, I pick up the copies of the video , on DVD , on Thursday will post it the same day, me and Tony Day # 455 ,watched it right through yesterday , what a ship load of memories. some of today's petals should watch it to see what it was like back then, Cowra program Easter Sunday 1972, 7 heats of the 500 B, 18 riders a heat, only 2 make it to the Semifinals, go hard or go home !!
Now comes the good bit. I tracked down Steve Anderson, #101 solo, #5 sidecar, and his dad Ray, ex showground sidecars in the era of Clacker Levy an Chook Hodgkiss, who made the original 8 mm and 16 mm Film and he still has them plus other stuff from that era and said I could borrow them to have them copied, am gunna see him at the end of the month
Will keep you posted

Hey Loop, the best thing about pulling the J.A.P. down for measuring in 1998 was to show that the rocketship was a genuine 500 & the rider/engine builder was the ticket. Aleast put it back together as a display bike at the Titles we could probably do it over a few beers.The Titles should be a great event for the year already 21 pre entries 5 in the Pre 75 slider class all that JAWA stuff. Cheers Grasman :D

Firko.
<The latest engine he bought is another Rickson 2V Jawa conversion engine, apparently it's the same as a Briggo, made before Rickardson sold the patterns to Barry Briggs>
Does that mean that Jonesy owns 2 Ricksson Conversion for a JAWA?
On the first Briggo Conversions there was on top OL Briggo because they where made by Otto Lantenhammer.
Also there is some difference between a Briggo and a Ricksson.

OK , OK , I know it's a bit off topic but you all may find this interesting , it's owned by Bob Sunderlands brother , Dave , I think , not sure , will find out.

It's in a BSA frame and is , so I've been told , one of the cylinders and head off an 1100cc alloy v twin, note splayed pushrod tubes and carby out the left side
