Hello Chaps. I'm in need of a little assistance.

I need to know what model of bike ran the Mikuni TM34 carb as standard. I've a feeling it was a Yamaha YZ125, probably pre 1990 but I'm not sure. Or maybe a suzuki RM of years gone by.

Can anyone help?

does this help?

I've already found several things like that, but I can't find anything stating model , year and carb spec. That's what I need.

Seems like a pain in the bum, which it is, but that's what I need to know.

Basically which year and model machine uses TM34 carb.

1996 Aprilia RS250 has Mikuni TM34 flat slide carbs: http://www.motorcycle.com/mo/mcaprilia/rs250.html

Some other info:

Hope you find what you're after.

Cheers.

I think some 99-02 Gas Gas 250's use either TM / TMX or PWK - later Gas Gas is deffo big PWK.
Early RM125's used a PWK 32 / 34 which are great - the PWK range was designed for idiots to use and set up - they work on anything.
Later RM's used something a bit obscure but I don't actually know what it was I'm afraid.
The YZ (pre 90) would most probably be a Mikuni due to what Yam were doing at that time so I'd go for the RM but you gotta find 2 of them and then nick the choke circuit out of something like the offside PWK28 from a KR1 etc...
I happen to have already completed that quest and it took 18 months of watching e-bay and scavenging bits.
Good luck !

My 1950 BSA doesnt use one and nor does any Norton I've ever come across, so theres another 2 bikes you can add to Binka's list of bikes that dont use TM carbs, hope that helps you Matt.

I think you'll find Ducati's don't use them either!

Hey, by the time we've listed all the bikes that don't use them, you should have your list Matt!

Oh, the Ariel Leader square four (or Squarial as it was affectionately known!) didn't use them either, so cross that one off the list... er, or is it add that one to the list?!

Oh bugger!

I've just checked and my Honda Dream doesn't have a TM, neither do any of ny NSRs.

What to do?

I think we've eliminated quite a few now, and we can knock my Mazda pickup off the list as well, and the Toyota pickup 'cos that's a diesel.

Maybe I should just nick the carbs off Paul's Aprilia, that'll make him spew

okey dokey

YZ125

01-06 36mm
96-01 38mm

The only year I know that used the 34mm carb was 82ish to 86 a VM34SS model, but iam sure they changed to a TM or called it a TM, read some were it was TMX around 87 and TMS 92 onwards.

maybe it helps maybe not.

But you aint coming round to knick my carbs!!
