Need help finding bolt sizes

[njcafe84]

I'm trying to change my bolts over to hex head(Allen) bolts and I need to find out the sizes for two locations

Handle bar clamp bolts(the 4 bolts that clamp the bars to the triple tree)

Points cover screws(2 Philips head screws there now)

Anyone know the sizes or know of a parts diagram that will show it?

go here find your year, model... find your part..... yamaha part number read like this for a bolt 90106-08032-00 the center number 08 =8mm 032 =32mm long

I don't mean to be a smart @ss, but what has always worked for me is removing the original bolt and taking it with me to the store. If you are ordering online, remove them and measure.

I need the thread pitch also. Not just the length of the bolt otherwise I would have just measured it

go find a thread pitch guage and have at it, this ain't rocket science those bolts are going to be standard metric pitch for there size

Also as a good rule of thumb, if you have a hole with no bolt, when i went up to yamaha uk for a new model and update course for work, one of the mechanics there said that "if you put a bolt in and from the edge of the case to the base of the allen head should be double the thickness of the bolt itself" So say a bolt is 8mm thick, it should be sticking out 16mm to be screwed in, that way no hitting a dead end and cracking a part/case or stripping a thread.
