After about half an hour of riding today I came to a stop at a light. My idle was down around 1k and it was running really rough. When I left the light I was almost wide open on the throttle and barely moving. I went directly home, parked and noticed the smell of gas. When I looked under the bike I saw gas leaking out of the carbs through the air filter. now I'm wondering why this would happen and how to fix it.
Carb floats could be stuck open. It might be time to clean or rebuild those carbs. I have heard people have temporarily fixed them by draining the float bowls to clear out sediment or giving them a light tap to get the value to seat properly.
Pulled carbs and cleaned what little specks of dirt that were in them. Removed float bowls and checked floats. Can't seem to find any reason they would be sticking. put them back together, re installed on bike, started the motor and promptly did gas start leaking out again from the filter. Any other thoughts? I'm stumped and getting quite frustrated.... :dunno_black:
this might have something relative

When you took the bowls off, did you check the condition of the needles and seats? How about the O-ring on the seat? They might be worn. Also, if the upper "vent" nipple on the carbs is clogged it could cause both carbs to leak. First thing first, remove the air filter and turn the gas on. Is it leaking from both carbs or just one? Also, remove the float and shake it. Can you see or hear fluid in there? If you can, you have a cracked float and it needs to be replaced. If you take the bowls off and push both floats up while blowing into the gas line, you shouldn't be able to move any air. If you can, then something is wrong w/ the needle/seat/o-ring area. If you can't blow air, then something is causing the floats to not close properly.
Checked the link given deros.. the breather hose that was plugged in that example no longer exists on my carbs. I removed that hose at rejet.
As far as the floats go. They are solid, dry and in mint condition. Will remove air filter and check needles, o-ring and seat and keep you posted.. what should I be looking for when I take it all apart

Removed air filter.. gas only leaking from right side carb. Took the top off the carb, removed the diaphragm, needle and slide and checked condition of all of it. Everything looked ok. Put it all back together and made sure it was all seated. Still have the leak fom just the one carb. Stumped at this point and have a 500 mile trip planned in 3 weeks. Any ideas left out there, besides the last resort of takin it to the dealer?
Check float height if ok check the seat that the float needle fits into pull the seat and there`s an O ring in there if this weeps its the same as the bowl sticking open.
