I did not vent the gas cap for now. I was thinking the existing vent on fuel tank would be enough. I might have to do it finally.

For fuel level adjustment, is it supposed to be 3mm over or under mating surface ??

My adjustment is under mating surface as I read in service manual. I know in tech article it say 1-2mm, I figured being 1 more would not be a problem... Maybe Im wrong.

Manifold is brand new with new gasket from begining of summer. Maybe I will have to check for leak.


Above the mating surface.
Checked on the manifold side of the carb. Its harder to check on the manifold side, but the mating surface on the aircleaner side is lower. If you use the aircleaner side you'll be way low.
With the carb on the bike, and the bike upright, not leaning on the stand.

Yamaha changed the settings so all carbs use the 04 and later setting of 4 to 5mm above. Anywhere from 3 to 5 should work fine. You don't want to get over 5.

At the very least remove the rubber plug in the cap, on what would be the high side of the cap, when the bike is on the side stand.

Good to know, I'll have to re-adjust it. At least I made it with the right side of mating surface at first !!
It might solve my problem. I wish I'll be good to go without venting the cap.
