New pipe question

[Draven]

Plan to get exhaust, dasa or rossier, in a few weeks for my 08' wondering if i have to rejet or change anything dealing with the carbs/motor ? or can i install and ride?

you will need to rejet carb

you should rejet the carb. If you dont, it will be UBER lean and crack your headpipe (eventually). Im not an expert at the 06+ jetting so i cant help much. But i think most people run a 165 main, but dont hold me to that

better safe then sorry anyways i guess, i forgot to mention i have the HRC kit witch they give you a new head pipe and rejet and adjust valves if this information helps either way ill just invest in a dyno jet kit

thanks.

If u already have the FULL HRC kit installed, using all of the HRC jets, air box lid off and all already then you most likely won't need any further jetting changes when you get the exhaust.

At most you might need a larger pilot jet.
