I have a 250r with a Pro-x 310 kit. I have a FmF fatty pipe and silencer and K&N filter. I do, have a 38mm carb coming. Should I put a reed spacer in and what type of reeds or reed system should I put in? I mainly need the low-end to mid range power. Mostly ride trails and occassional mx. Also, I am running 32:1 ration on fuel. is that too rich? Any help would be appreciated. thanks

 

Get an esr trx-6 pipe, it is increadible. With your 310 it will pull like crazy, makes it feel almost four-stroke. As for the reed spacer, I hear it does little or nothing.

Also if you are looking for low-end power you shouldn't get a 38 carb, bigger carbs give you more top end at the expense of low end power. You should get a 36. A smaller front sprocket will help too.
