Suzuki TS250 hot up kit question

[Bamford#69]

Hi,
I bought a 69 TS 250 , orange diamond pattern seat, steel forks 19in front wheel and bought a Suzuki hot up kit ,  up pipe right side  no muffler didn't have to, very noisy, , B O S
cheers

So what it looks like to me is that the early TS models like Arizona Mikes bike used a GYT style pipe but the later TS's used the left side down pipe like mine and Docs. So my next question to my learned colleagues is....Why won't the TS kit pipe fit my TM 250L? Both TS and TM exhaust ports exit the cylinder on the same side and the TM and TS frames are very similar except for street brackets and bolt ons.

I'm still hoping someone can identify what I was told is an RH pipe. Should an RH pipe fit a TM ? When punters fit RH cylinders to their TM's what pipe do they use?
I'm selling both pipes fairly soon and want to identify them so I can list them correctly. .

And the rear brake lever which is also completely different on TM vs TS.

id say that rh pipe is a rh75 pipe,look at the detail in the 75 pic blown up and the rm250/370 slip joint out of the cyl.johney o should be able to tell for sure or dave#6

Geez Firko those pipes look like taipans are breeding in your backyard! J

I think Tossa is right, and the "hop-up kit" with the downpipe came in with the TS250R. I worked in a Suzuki shop in the late 1970s and we had one gathering dust on top of the parts shelves. Must see if it is still there... I am not certain about the earlier TS250-IIs though.

Mark, I'm no Suzuki guru, but look carefully at the exhaust exit/manifold on the later TM barrells (M & I think L models) compared to the early ones (J/K). If I recall correctly, they are quite diff to the early TMs & TS's & come out at a completely diff angle. I'd hazard the guess that thats the major cause of the misfit.

The other pipe does look to me like a 75 RH pipe, & if it came from who I think it did, he would surely be correct. Since the later TM exh manifolds appear somewhat similar to RH's, it may go close to fitting the late model TMs, but there's no guarantee the exhausts exit from the cylinders at the same angle (probably unlikely) - not to mention diff frame, shorter RH engine etc

[Doc]

I have it on good authority (don't you just love that cliche ) the early genuine RT (Race Tuning) kit pipe offered was the down pipe and also an up pipe option added at a later date. Just when that later date was is a totally grey area. JC is correct about exhaust angle change for the later '74/'75 TM250 compared to the early TM and all TS's. I'd also hazard to guess the 2nd pipe is '75 RH

[Lozza]

That's correct the angle of the exhaust duct is different on the TS and TM, oldfart had some pics somewhere

Thanks gentlemen....this is another example of this forum being the best vintage dirt bike brains trust on the internet.
