Finally took my 06 ttr to a mechanic, i am going thru just brake light filiments, not running lights. He thinks it could be vibrations of riding at highway speeds. i am sick of changing bulbs every couple of weeks.

Hello folks, I came across a yamaha workshop manual recently and noted the main jet size is listed as 137, mine has a 147 and an FMF powercore pipe, does this sound correct as I am diagnosing a dying issue after a short "coshing", starts again easily with a little choke (weak), the pilot scre...

I have a 2004 TTR 250. Right in front of the head cover there is a hole. When warm there is oil that kinda percolates out and drips on the exhaust and smokes. It looks like there should be a bolt in there, but every part finder I see has the hole but no bolt identified. Can someone please tell me what this...

Having just rebuilt my TTr top end it all runs but only in neutral , as soon as I put it in gear the engine cuts - it won't restart or even turnover except in neutral - so how should I eliminate the problems to find the source??

A couple of weeks ago I left the bike idling on full choke for a couple of minutes and left it running. I came back to see the battery box smoking. The result was an approximately two inch hole melted on the edge of the cover. I thought that this was down to me leaving the bike on idle too long but now I'm not so s...
