Hey guys got a question, I recently rebuilt my 2005 CRF 250 and updated to the 08 piston for slightly higher compression. I also put on a full Leo Vince Exhaust system but haven't yet played with the jetting. I rode the bike a bit and it is really hard to start cold and seems to bog a bit. When you take off it revs out somewhat then builds a few r's then revs out better before it makes power. Seems like to me its running really lean. Anyways anyone else got a setup like this or anyone know some jetting suggestions?

Thanks in advance,
