I should be getting my cylinder back in next few days from Eric Gorr after getting it bored and his Mo' bettah porting specs. I'm curious as to why kind of jetting I should run in the bike? I'm at sea level with temps currently in the 70's. The bike is a 2001 CR250 with PWK carb. When I talked to him, he said I may want to go leaner than stock jetting because the porting is more efficient, but I would like to see what you guys who are running this setup have found...
