Here's the deal... I bought my '00 400EX used a few weeks ago. The previous owner said it was jetted with a 155 main jet. He gave me a stack of receipts with it too, as the shop did all the work on it.
There is mention on two receipts about them selling him some various carb jets, but nowhere is there talk of a needle, or a full jet kit (from Dynojet or K&N or anywhere else).
So I'm wondering... how would a 400EX run with just a 155 main jet and a full Big Gun exhaust (header and muffler)? Also, how would I tell if the needle in it now is a new one? I'm tempted to open it up to see.
