....:confused: wow you have tried everything ehh? make sure nothing is blocked. so you got the air box off and everything is new and it sounds like you have messed with the carb enough to not have it set wrong. are you just simply using to big of a jet? maybe try taking the silencer off the exhaust just to see if that helps, if it does maybe buy an after market pipe if you dont mind it being louder.
maybe im missing something in my thinking process. make sure your choke is all the way off.
try jetting down, is 95 the stock size? maybe your using a different style jet than stock and the number system doesn't match (one type's 95 will be different from another's 95)
hmmm maybe someone else has something?
i mean its freshly rebuilt and everything...

good luck
