If it's been rebuilt as described it worth every bit of the $750 being asked.
I'm intrigued by the "Ignition system; Electronic with electronic advance, comes with brain box, coil, kill switch and wireing. This is a slightly heavier flywheel than the Yamaha YZA internal rotor system. (Very trick, great power band with the larger flywheel and electronic advance) all parts for ignition come from a Kawasaki KX80 2000 to 2008, modified flywheel taper to fit the stock YZA Crank."
-
yer i have been studying that ign, im not sure he chose it cause it fits or because there easy to buy. he would have still stuffed about getting the taper on the rotr changed, but saying that why not a YZ80 or a Cr 80 etc ? whats the draw card, the bulky flywheel and weight.
interesting any way. what i dont get is why he would think its a good thing that he ground off all the Engine numbers, i know where he bought the nos clutch etc from, so im even begining to think its RT1 morphed with YZ stuff to create a rebuild YZ motor with the obvious YZ stuff fitted. id be interested to find out if that gearset and crank are YZ and from that motor.... or

Your loosing it Freaky....just buy it, you know you want to......have you sent my shit yet?

If you are interested Freaky talk to the guy. I think he is a DT/RT regular. I think this is some of his previous work.He does good, dedicated, informed work.

NO sorry.... im waiting to post it with the stuff to stewy. Find me a 18" 36 hole rear rim for cheap and i wont need to hold back the post..........

The motor went for 2 grand.....just shows you that YZ250/360A's are THE most sort after and valuble japanese motocross bike EVER made.....Elsinore shit....ha ha......not counting "Works" bikes ofcourse. ;D

Yeah not counting RH Suzukis I guess. I have been looking for one for a while now. One day I will pounce.
-
An RH Marc or a YZee....I can do you a deal on DJ's one at Easter when I pick it up.....pigs ill fly before that one ever goes ;D.....I just need a 360A to go with my collection.....one day ;)
-
Was about $800 tooo expensive. PArts in the rebuild would at best be $500
-
Your on drugs again Freaky....it even had a trick ignition....I thought 2 grand was cheap....the NOS clutch cover and clutch actuation cover are worth more than 5 hundred....if I was looking for a spare engine I would gladly pay 2 grand....like I said, you must have had a big day today....now wheres my parts?
-

A YZ250A would be nice, just waiting on something suitable in bits to turn up.
-
I have one in bits or more of a complete core bike if you are interested. Tom
-
Perhaps I've lost track of the market but that "YZ" engine looked a fair bit overpriced. Sure the clutch side cases are expensive if you can find them but if you're restoring an all points resto, money's no object. If it's performance advantage you're looking for there's nothing that can't be easily done to a $20 DT2 reed engine barring the gearbox ratios (which I'm told can be closely replicated with a little mix'n'matching). As far as the KX ignition being trick.....well perhaps it's a bit more advanced that the original but it ain't no PVL or anything as trick as any of the other quality aftermarket ignitions available today.
-
Guy's Chuck Davis is the person that sold the motor and it is 100% YZA parts. The motor was offered to me before being put on Ebay and we discussed it extensively. The cases are original 431's because he purchased them from me a few years ago. Chuck does everything top notch being that he is a roadracer and a very good mechanic. The motor was intended to go into a roadrace frame but he wasn't allowed to have a reed cage motor. The clutch cover,clutch actuator (and push assy)are NOS as stated. I don't know who won it but they are getting a very nice engine. Tom
-
That's cool. As long as it's 'genuinly genuine' all is well. I based my "DT1" suspicion on my and another mates impression after viewing the shots. It just goes to show that we can all get it wrong (sometimes) ;D
It's still expensive but I guess the YZa market's changed since a mate (the same one who thought it was a DT1) bought a 360A engine at a Swapmeet for $50 back in the mid 90's. I'll remove my evil accusations. ;)
-
I understand, I would have assumed the same things had I not known Chuck. If anyone needs any YZA parts I have a bike and some spares to sell.
-
My YZ250A motor is stock as a rock bar the 38mm carb, everybody thats riden it when they get off go farrk.....you would have to spend a shitload to even come close with a dt2 style engine....why bother when the real things available....and its not just the barrel, they have trick cranks, gears and shafts, clutch basket, anyone who's seen inside one of them will know. Like Tom said, whoever got it got a bargin.

I bought a complete used one last year for $800 which at the time i thought was mental for a used motor, but when i sat and thought about it after a set of $60 seals, $60 worth of bearings, id still have the best part of a fresh motor, chuck a piston at it and i though thered be another 30yrs of racing in it. in the end i used a Rod and a spacer plate, but still under a grand and its all fresh again
Granted that one has some NOS stuff in it , but unless your doing some kinda resto is it a bit of an over kill to put in a racer ?
im just a bit confused, why go to all the effort of wasting NOS clutch basket etc, just to stuff it in a racer based on the differant ignition.
maybe IF it had the correct ignition etc i could see it fetching thats sort of money to the right restorer, but not with that ignition and the fact he ground the numbers off ? ???
I just would'nt think a restorer wouldnt go down that path. or as a racer i be thinking put the NOS stuff back inthe box and save it for a rainy day or sell it to a trainspotter who might pay enough anyway to fund the motor.
Anyway not to worry just seems a strange mix in no mans land to me, its not one or the other. FWIW id pay $1500, but id want to be sure it fired up and run with that ignition. ;D
-
Too late to start grovelling ;D
-
you must have had a big day today....now wheres my parts?
im waiting on a Rim for the slider to turn up and then i was going to post that, and send your stuff with the PE cover etc to stewy.
I still have to remeber to post a piston to Tossa and find that ign off to MIchael PE, i just have to get around to it, im not getting any younger and when i blink today is now yesterday :-\
-
YOur on drugs , Why grovel ???
now go find a alfa to do a service on.
idle hands................

Tossa - you could be waiting a while - I think my piston is on back order ;D
he he he!

So Did you pay for it Ross ? You pay i ship ;)
i dug you out this one ages ago, with the trick single ring, so you can cut in your own intake window to exactly suit yZ360 spec, even found the ring but dont remeber if your using a chrome bore so thats optional. just been waiting for you to get back to me ::)

I'll reply for Rossvicki!! "oops sorry i just have to change my wardrobe, will this outfit go with the white of the tank!!mmmm" Now what was the question!! sorry Rossco couldn't help myself again, nah STILL!!
-
Freaky - love of my life - that's the first I know? Mind you you will probably come out with record somewhere now of where I did committ.
shall PM you
thanks buddy.

I just figured he was over fighting with the black fellas in tunisia again. and he was ebaying by getting them to beat the drums to the next township with the interconect and some 12 yr old boy was typeing into the search engine for 4cents an hour. Just dotn give him your credit card number Rossco p
-
2K for a full YZ A motor IMO isn't over the top these days. A good full bike is closing in on the 10k mark now. IMO the A was always trickier than the B
-
I'll second that.
-
well thats a given. B's are so 1975
Twins shocks all the way
-
A's are the preferred rides here in the states because the Vintage classes are 1974 and older . The B's have to run against 75,76,77 models and some of them are light years better in the suspension area (twinshock bikes w/Ohlins or Works shocks, 38mm forks etc) so the B's are mostly for restores not competing on. If given the choice A's are just cooler looking and more valuable here so they are my chosen racebikes.
-
HEy TOm, Davey, anyone i have always been stumped on this part of the frame, none of my A's have anything attatched to it, nor does it seem to serve any purpose i can figure out. But it must be there for some reason cause it wouldnt just be there to add weight.
What the hell is it supposed to be for and/or if it was a redundant part that never come out on production what was it they were going to use it for ?? any idea - has always had me wondering ?
my only thought was for a underslung pipe perhaps ?

It's the same rule here Tom....Pre '75 it is. There's a bit of a story as to why the YZB is allowed in our pre '75 class.
Back in the early 90's a guy named Jody Mason took our governing body, Motorcycling Australia to task over not being allowed to race his YZB in pre '75. He argued that as the YZB was designated by the Yamaha factory to be a 1974 model he was within his rights ro race his bike as long as the 7" and 4" suspension travel criteria was adhered to. He used the '74 Maico as an example of a bike with too much susprension in stock trim being allowed to race as long as the rear suspension was retro modified back to 4" of travel.
After verification from Yamaha and submissions from racers who raced B models in 1974, Motorcycling Australia very reluctantly had no choice but to allow the YZ 250/360B to compete in pre '75 vintage motocross and dirt track. Ironically Mason never raced his Yamaha YZ250B and soon left the sport. Since that decision was made, a small number of YZB's have from time to time competed but to my knowledge none have shown to have any advantage over any conventionally twin shocked bikes.
This was an extremely controversial situation at the time with many, including myself declaring that allowing the 'B' to compete in pre '75 would cause all sorts of problems but now, nearly 20 years later it's seen that allowing the YZB in had little or no effect on the integrity of the class.

Geez Freakshow......I thought you where a guru....its for a right hand gearchange and thats what the rear brake cable attaches too....if you look up Terry Goods "mxworksbikes" site and look at Torsten Hallmans prototype YZ, you will see what I mean.

I have often wondered this myself and thought maybe it was for a chain tensioner?

right hand/ left hand just are double ended shaft and use the same holes in the cases ???
are you therefore meaning to say its for a left hand brake pick up ? if you look at the torston bike the rear brake is on the left but it pivots off the swing arm frame. THE THING ima talking about is not anything to do with the swingarm area and comes off the lower rail ?
unless we are taking about anothe rbike on Terry goods site ?
I have never seen a part number for a left brake and the sleeve is a differant diameter to the right hand brake shaft so im not convienced.
I need to see a picture with soemthing in there........
My other thought was a rearbrake stay or pivot or again a pick up for an underslung.
-
That bracket is for the L/H brake pedal. Did you READ the story about the bike and not just look at the pickies?....send those parts before you read about it!! ;D
-
and Firko - YZB's were available in Australia in 74 I thought whereas they didn't turn up in the States until 75 - hence being marketed as a 75 model over there but 74 here ?
-
Yeah I think that's correct Rossco, we definitely got the YZB before the Americans. It was the same with the '74 LTR Maico. We got them in late '73 while the Americans didn't get them until the second half of 1974, hense the 74.5 designation in their press at the time. I was told they held off on US release to get rid of the remaining '73 model floor stock. If the forward mounted 74 model had been released at the same time as Europe and Australia got theirs, there would have had to discount a shitload of superseded Maicos.
I suspect it may have been the same story with the YZA/YZB.
-
The YZB in my opinion should be allowed in AHRMA vintage given the fact that Yamaha won the 1973 World Championship on a monoshocker (Hakan Anderson). I also think that if I was allowed to race it I would be at a considerable advantage due to the fact that the monoshock would let me hit jumps a hell of alot faster than I can with a twinshocker. I only say this because I raced a 75 MX250B in some local modern races and did fairly well against modern tracks and jumps. I won the 40+ class by a good margin and 2nd in the sportsman class (only because a local national race was cancelled) and these races were a breeze w/ my YZA , I can't imagine how it would have been w/ a YZB.

Nah just the picies. still dont mean its in the right place though. so if his is on the swing arm bolt what did they put one underneath ? sill japs.
update. read the words where does it say thats what this bit is davey ? were talking about the 71 reed bike arent we ?
