2011 Klx 250s and fmf exhaust question, help please!
None on mine, and I had to remove the metal bar dampers when I installed my bark busters.
definite difference w/ jut the slip on. the jet kit i will be ordering shortly.. that will take care of the backfiring im experiencing on deceleration. and i will all the air box mods as well while the bike is apart.
Thanks
