Question about 2000 Yamaha YZF-R1
HOPE YOU CAN HELP, PRODUCT CATAGORY DOES NOT INCLUDE ATV's
I’m trying to get a friend’s Yamaha Timber Wolf ATV(year unknown) running. I was able to get it started but it won’t idle and runs rough off idle. I noticed a plastic hose that was partially filled with gas attached to the bottom of the Mikuni (model YM) carb bowl that was routed and dead-ended above the cylinder head. I believe the dead-ended, or open end of the hose should be connected to something as the end is somewhat flared (like at one time it was connected to a fitting nipple), plus, no manufacture would ever route an open ended hose containing gas above a hot cylinder head!!! All this said, I can’t find anything that this hose could be connected too, and the Mikuni web-site pdf manual for YM carbs shows a plug on the bottom of the float bowl instead of the nipple fitting/hose that is on the ATV in question……. Any help would be appreciated!!!
That was an atmospheric vent you found that should not have gas in it. If it does, the carb has over flowed. It probably needs to be cleaned with special attention paid to the needle valve and float assemblies.It is routed up high to prevent water and debris from entering it and clogging it up. It should have holes for it to pass through on the snorkel coming out of the air box behind the gas tank under the seat.

That hose is just a drain for when you loosen up the screw on the bottom side of the float bowl, be sure that the carb is cleaned very well, make sure you have good compression and spark. ( blue spark ). only need those three things for it to run.
