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...

Ended up leaner on pilot, leaner on needle, mains were maybe a little leaner, the 265 made the jetting on mine more consistant i dont have to rejet as much.
