Drz 400sm?

[Dempsey88]

i was thinking about getting a slip on exhaust for my drz sm and was wondering if you evan had to bother with jetting.

Dont even bother with the slip on just makes more noise. Spend the money on the jetkit and do the 3x3 first

If you just do the slip on you probably won't need to re jet, 3x3 will require it.

its gonna backfire like crazy on decel if you dont rejet,bikes come real lean already from the factory

if its a full system it it must really run poor!i have tons of people come in and say thier bike runs good and like the decel popping but in accualilty it is super lean, hot, hard starting and runs poor.
