Hi all , I have a RT1-360 with a dt 360 tank. It was sitting in a friends shearing shed for twenty years that i know of,it has matching engine & frame numbers . The tank is in good condition with 3 little dents in it & the engine cases are good as well . The bike is at Mullaley which is 50 kms west of gunnedah NSW . Asking price is $400 ono.
I am happy to e-mail photos or info.
Been trying to up-load photos on this post but it just wont work!
There are pics of the bike in an album on this site.

That's a stock RT2 tank - which is why the colour matches the colour on the headlight mounts.
DT360 tank doesn't fit onto an RT frame - the RT frame is too wide at the rear.
-
Thanks for your input Nathan!
-
Nathan are you sure RT2 tank? It looks like RT3 tank to me in fact all of what's there looks like RT3
-
This is what I think was the first RT1 tank (the yellow stripe).
(http://i323.photobucket.com/albums/nn458/mx250syd/RT1/rt1mx.jpg)
This was the most common RT1 tank (red stripe).
(http://i323.photobucket.com/albums/nn458/mx250syd/RT1/0c39_3.jpg)
This is what I would call the RT2.

This is what I would call a RT3, an all silver tank no stripes (250=burnt orange tank).

it couldnt be a rt1 cause it's got a reed valve,rt1's were piston port
-
The bikes with the nike stripes are AT3, CT3, DT3. RT3 etc, no stripe is AT2, CT2, DT2, RT2, pinstripes are the 1's.....now what welding process do they use for a tank, and what type of filler rod do they use, wheres Nathan.....haven't got his speil about welding?...come on son.....and NO WHY questions!!! ;D
-
DC, In this case, the answer is "steam pipe"... :D
I thought MX250's summation of the models (and their fuel tanks) was correct, but I'm still to get my head around the exact differences between RT2s and RT3s (and DT2 vs DT3s) - everytime I find someone who insists on a particular thing, I find someone else who is just as insistant on the opposite.
I think there are two main reasons for this:
1. Yamaha made lots of rolling changes so a late RT2 will have some of the RT3 updates (for example).
2. The xT3s were more a marketing/cosmetic thing (rather than any real mechanical changes), and consequently a lot of documentation considers them to be the same bike.
As my interest in these bikes is more about racing them that nut-and-bolt resto, I've not needed to know the train-spotter stuff.
-
Nathan, I think the only difference between the "2"s and "3"s is the nike stripe, it was one of those Honda updates.....different decals for the next model.
-
I owned about 3 X RT 360's in the late 70's. There always seems to be confusion between the 1,2 & 3.
For example this is the 360 I have sitting in my shed waiting resto when I saw it on ebay I assumed it was an RT2 or 3 but the frame and engine numbers, which are matching all start with the prefix RT1
And it has a reed valve. It looks identical to Blowkat's.

To the best of my knowledge they all had frame numbers starting RT1 - confusing eh!

OK. but I could swear I had one years ago that started with RT3?
But it was a long time ago and there has been a few 'over the bars' since then and probably brain damage ;D
-
THey all start with the Dt1/RT1 its the numb er sequece that cuts over, even the 2mxers have the same prefix, just a differant starting point on the number sequence. BArrell picks it, the rest is just cosmetic stuff or any internal etc so little you would nt worry.
Tanks are round on the early then as you say change to that other teardrop style, I have a teardrop on my RT1 and its ealry so im not sure when the tanks changed and became Dt360a
-
....... and its ealry so im not sure when the tanks changed and became Dt360a
with the new lowered frame ;). All DT250/360 and MX250/360 tanks are held on by a welded on bolt on the frame at rear, with large washer and rubber isolation. DT/RT have a dickie little rubber band with canvas tag for stretching into place over a hook on the tank (worth a small fortune NOS ;D).

Yes.
The tanks changed because the frames changed. The DT1/RT1 has a single backbone until just above the carb-airbox boot, while the DT250/360 back-bone ends under the seat/tank junction. This change makes room for the exhaust pipe to cross over the top of the motor, and travel along under the tank/seat within the frame.

True Story
First RT1mx over here in the West straight from the crate to 1st MX meeting as a promo New world beater 21 in front wheel black tank ;D
Large crowd gathered
The 3rd kick spat the kickstarter idle gear complete with shaft end up though the top crankcase.
As the Yamaha salesman Guess who was kicking the bloody thing
Never sold a single true RTMX after that ::)
-

I was led to believe they all started with RT1 as well so I went out to the mancave and checked all of my RT1/2/3 engines (6 of 'em and I was right, they all start with RT1. The engine I've built for my Cheney only has RT1 and no numbers. I'm assuming that they must have been a replacement set of cases. Any other ideas for the lack of an engine number?
-
CAnt find my Rt list, but the Following DT250 numbers were the reserved start numnbers for the following series :
Dt1 (68) DT1-00101#
Dt1B (69) DT1-15001#
Dt1C (70) DT1-50101#
Dt1CM (70) DT1-95101#
Dt1E (71) DT1F-00101 / DTF-020101#
Dt1MX (71) DT1F-090101#
Dt2 (72) DT1F-105101#
DT3 (73) DT1F-135101 #
Dt2MX (72) DT1F-185101#
DT250A (74) 450-000101 #
DT250B (75) 450-200101 #
DT250C (76) 450-500101# was the case up
Also its my understanding is numbers under 101 were held back in the factory for testing, sponsorships, teams etc etc and that was the case until at least 1980 ( G series)
-
Not sure firko but as there are no ribs under the letters, they can be ground, but if its clean flat metal then its how it was. I though Most ealry case replacements where blank, but im assuming cause they looked so similar to the DT except the stud spaces, maybe the prefixing was to insure they werent mixed up in the spares shops and wrongly sold with the 275 cross overs on the 214 motors

1973 RT3 360 1 Baja Brown RT1-125101--150994 RT1-125101--150994
Well bugger me i have opened a can of worms here ,So i went looking today and found a web site with all the yamaha serial numbers.
All i did was google yamaha rt1 360 serial numbers , And the numbers above are what i came up with.
So now i have a bike for sale which is an rt3-360 which is up for grabs with the best offer.
I hope this web site clears up a few queries for everyone on their own projects.

I just put a short story on here but my computer turned itself off when i tried to post it so here's the basics -My RT1 had YELLOW stripes under house paint on the original tool box, gear selector shaft comes out both sides, has not got reed valves. Every one said it should have red stripes hence my interest in the previous posts.cheers wally. [The tank had house paint also.]
-
gear selector shaft comes out both sides,
It's one of the earliest ;). I'm not sure of when they dropped the ' gear selector shaft comes out both sides' feature, it may have been mid-way through the first model (same with the change in strip colour).

Wal...my original RT1MX had a yellow stripe. The first 1970 production run had a yellow pinstripe but when the second run emerged they had a red stripe. I'm pretty sure the yellow stripe production run was pretty short as my mate had a red stripe RT1 at the same time I had mine and I remember that the engine numbers were within a 1000 of each other.
-
RT1 and 2 had 19" front wheel. RT3 had 21" from memory. Jerry
-
Thats what I tho't Jerry but the RT3 pictured on pg1 looks like 19" to me
-
Could be. Hard to say. My old man had a brand new RT2. I only found out it had a 19" when I tried to fit a 21" tyre. DOH! Jerry
-
21inch steel rim on RT3, 19 on all the others OK. Info from genuine Yamaha Aust spec brochures . SFA else different except paint and yes the RT3 still could regularly kickback like a fooken rapid mule.

G`day all,
just a quick question regarding these bikes as i`m no expert on what could be done to them performance wise.
I came across a couple of old bikes sitting in a workshop today while dropping off a car there, the Yamaha i was looking at started with the RT1 pre-fix on the frame though i didn`t take any notice of the frame numbers.
The guy i was speaking with said his brother used to do some desert type races on it and it was modified to be a 500cc, was this a performance kit available back in the day or simply a one off by somebody ?
Apparently the parts are all there to put the thing back together except for the piston which needs to be modified to suit, the previous piston destroyed itself hence the reason for the bike being in pieces.
It has the single tube pro taper type bars on it complete with the old style hexagonal shape blue grips, the front guard has the extra piece screwed to it to make the guard longer. Any ideas ?. Peter.
-
That ''500cc'' kit sounds like a bit of a stretch but it may have a GYT race kit in it. If it does indeed have a 500 kit it's most certainly a home made deal. The RT1 is quite legal for pre '70 class and can be made competitive with a wee bit of work. The handlebars sound like solid alloy Inter-Ams which were popular in the day, as were those awful Hex-Grips.
What colour was the tank? Is it for sale? How much? Have you got any photos?
-
As Firko said, I'd be surprised if it was actually anywhere near 500cc.
If its got a reed valve, then its no good for pre-70 - unless you fit a pre-reed top end.
Front guard extended is most likely the optiona B-model part c1975. I'm happy to be corrected, but I'd say that the same is true of the bars and grips.

Thanks Firko,
the tank looks like it is in a faded yellow undercoat, i will confirm next week if it is for sale and how much, and no photos as yet, i will try for more detailed info regarding the 500cc side of it. Peter.

First 360 had the yellow stripe.
Second model had the red stripe.
I bought quite a lot of kickstart idler gears, as the kickbacks cracked them. I also had alloy
welding done, to repair the clutch cover on two bikes, as the kickback also split the
casing where kickshaft comes out.
Sons of bitches.
Which leads to the philosophy of kickback. You needed to be committed, and kick hard.
Catch 22 - you were too scared to kick hard!

Correctomundo Rog....I had a yellow stripe RT1MX that Pete Geohegan imported into Autralia from America in pieces in the boot of his Mustang touring car. I went through a hell of a lot of kick starter gears and repaired my cases at work on a regular basis. I also used to carry a little tin of flywheel keys as my bike had a bad habit of sheering them with regularity. Despite the bike being such a pig to start, it went like a fuel dragster, almost as quick as my 350 Maico.....well, actually, the Yamaha would peg the Maico in a drag race but their abilities became miles apart after the first corner or even the first slight bump.
It's kind of ironic that I've now gone back to fiddling with RT1/DT1s. I've just been out in the shed pulling down a DT1 engine helped along by a bit of Herbie Hancock on the stereo, the aircon on full blast and a few 'Fat Head' lagers to help the concentration/relaxation mode. A cool afternoon working on a cool engine :).

Wrong first name, but this I think is the car driver (#5 at rear). Or, where there two brothers ..?
Engine casings are very shiny - bike looks new

Yes to both: Ian/"Pete" and his brother Leo.

Cool shot ....that's big Pete (Ian) riding the RT1 that eventually became mine. I don't have a picture of it at all sp that's a keeper. The bike met a terrible death when Porky Drake, the bloke I sold it to wired the throttle on full, slammed it into gear and launched it into the Pacific ocean off North Head at Maroubra. Even though the bike was past its glory days and in less than pefect condition after Porky had flogged it almost to death in the bush at Menai, it was no way to treat a bike with a bit of history (and a rare, genuine MX as well). I still get a little shitty when I think of it. :'(
The photo appears to be taken at Amaroo Park...you can bet that Kevin Bartlett would have been there on his 501 Maico as well. Those road racing blokes were like a roving rat pack, they all had big bore dirt bikes and flogged the shitter out of them. I think Geohegan bought a 360 Greeves after selling me the Yamaha.

"Those road racing blokes were like a roving rat pack, they all had big bore dirt bikes and flogged the shitter out of them."
I also have a photo of Bartlett practising on a DT1 for one of the Sunraysias. (Sorry - cannot load it up; am back home from
the office) They probably used him as a celebrity, to give the promotional article more weight. Everyone loved the Sunraysia.
And I think DT1s and RT1s loved Australia. It was the bike they had to build - for all the convict bogans Downunder, who
were crying out for more action.
