Hi all,
I am new to this forum so please be gentle lol.
I have a yamaha moto 4 yfm200.
It starts great, but misses and back fires when hold a stead rpm. If you gun it it will also bog down and stall.
I have stripped the carb out and cleaned everything, but still the same. I have also put a new plug in and changed the oil.
The carb on mine is a Mikuni VM22SH - INU00
I have read that the pilot screw has to come out 2 turns, but are there any other setting that i need to know about.
Regards
Stuart
