Raptor 250 Carb ??

[jaksdad]

Come on then, who has found a better, larger replacement Carburettor for the Yamaha Raptor 250, all we want is a simple no wires, no gadgets Carb, this will improve performance immensely obviously we have got the GYTR full exhaust system fitted, which we have had to source in the States, just trying to get that litle bit more without going inside the motor.
Any help would be appreciated, wanting to keep the original airbox and fittings where possible ?????
Look forward to your reples

I don't know if this helps or not. The Ratpor 250 has a 29mm Mikuni BSR carb. The Raptor 350 has an identical mikuni BSR carb except its 36mm. The Rhino 450 has the same carb in a 33mm.

Thanks for that but still looking for a more simple Carb to use, I am led to believe that the early Yamaha Trickers did use a 33mm carb, but trying to find info over here is pretty hard. Been trying to find websites that gave tuning info on the 'Tricker' but not much use, can't find none !
Any further ideas would be appreciated.
