Jetting For Wb E Series

[dle52]

If anyone could fill me in on what jets to use for my new White Brothers Pro Meg E Series silencer I would greatly appreciate it. I will be running the 400EX tween sea level and 6,000 feet. Also, I have a rev kit installed, will this have any effect on the jetting?

the rev box shouldn't affect the jetting. that altitude change will though. that is a pretty big difference. with the pro meg silencer, i assume your running the pro meg header too. are you running an air box lid? any other mods to the bike?

[dle52]

Not running an other mods except the rev kit and the K & N air filter. Air Box lid is still on it and I am not running the header pipe. Cannot find the correct one for the bike through White Bros. I run the bike at sea level and then do most my riding in Hungry Valley at approx 5000-6000 ft. Noticed you're from Southern IL, whereabouts? I'm from Central Illinois (Pana) but live in Cali in the Military.

i am about 20 minutes south of litchfield or 30 minutes north of edwardsville. its in the little town of staunton. at sea level, i would try the 155 keihin mainjet. at the higher elevation, you might want to go down a size or two.

So I take it that I'm safe from 155 to 152 and a 42 pilot? We'll see this evening when I put it on. Thanks for the help!!

BTW that is a 155 out of the dyno jet kit, not stock jets;)
