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?

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 !
