I have a 2001 yamaha blaster with a fmf pipe on it. What size jets do i need to use in the carbs to keep it from bogging down when i get on the throttle? i took the air filter out and it seemed to run a little better, but still didnt have a lot of power. please give me some suggestions.

 

full exhaust ? prob a 310 main and you only have one carb. It would be a good idea to leave the air filter on and take the lid off.

 

call fmf for exact jetting info
