[QUOTE="Blackcat, post: 1194974, member: 75988"] But when the short tooth and the notch line up as the manual says the one exhaust valve won't open all the way. That's why I'm so confused on this whole deal. But anyways about the picture. In the picture that little opening is my drivers side exhaust valve. When the exhaust valve opens that little hole closes. I'm thinking that little hole is there to let oil in so that gear at the top left corner of the pic gets oiled. Also the manual is a peice of crap. In one step I'll be looking at a 125 then in the next it will be talking about a 250. I think it is best used as referance only. But thanks for all your help. I'm thinking I'm going to leave it alone and try tinkering with the jetting. I know that's off a little cause all the smoke and spooge the bike spits out. See how it performs after I get that dialed in. [/QUOTE]
