Wont be racing til saturday i just got my jets for the pwk today and theres no port work its a bonestock vitos240bbk with a 72.5mm piston and all the bolt ons.
Your going to have a hard time without port work. If he is a bad rider than you might pull it out. Dont go any farther than 300ft or he has the advantage, launch in the highest gear you can, which without port work is probably 2nd. Hope the blasty comes out on top.
There is another possibility.... He will woop that 400EX ass!
Before you guys line up, shut his fuel off! just as a precautionary measure!
Holly sh*t your running that thing so rich. You would of done much better with a 158 or 155 main raceing that 4 poke.
yea theres some fat to be trimmed but i had a 158 in it and it ran lean.
