what carbs are these?? mikunis?? if so, jetting would prolly be similar to stock carbs. you need to be more up towards 300 with the main jet. pilot sounds right.. i bet its way lean. dont blow it up!!

Hmm... I'm not really familiar with those carbs but it does sound like your mains are way too small.. Your starving that bitch!

Im almost positive maybe for sure you need much bigger mains.

ok got 300 mains and it was better but still there.it did rev higher thow so i took some old jets and drilled

them out with a 1/16 inch drill bit and it is even better but still not right.dont know what size jet that would be

but still need to go bigger any help would be great thanks
