Bogged out and died after topoff.
Built the bike back up finally 3 days ago and wanted to ride before the snow hit. I topped the tank off (to the bottom of fuel tank cap hole) and took off, made it 4/10ths of a mile and the bike cut out. Waited a minute or two and it fired right up. It happened once more at the 1/2 mile mark. popped the cap, closed it and rode the next 30 miles uninteruped. I got home and checked the hose routing 3x and it is correct according to the shop manual. I am hopping that by trying to get every managible drop into the tank I over filled it and was cutting off the vent tube. Any thoughts?

Figured I was being an idiot. Thanks

I often overfill (trying to stretch my tank i guess) and haven't had that problem although it has been reported previously on several occasions. I rarely get off the bike to fuel so that it is sitting straight up when filling and so mine is up to the top 99% of the time.
You said you checked the routing of the overflow hose, but did you test it for flow. If you have a container of gas, put a bowl on the ground and pour some gas down the overflow hole and check for flow. If it doesn't flow quickly w/o restriction, stand back and throw a match in the tank opening, then close the lid (unless you want to toast marshmallows, nah, forget that). Better to just part it out. Should flow quickly out the bottom. If not, and if you have a compressor, direct some air down the overflow hole w/o blowing gas all over yourself to make sure there is no restriction or air pocket. The only other thing I can imagine is that the hose end is directed forward or oriented in such a way that air is stopping flow while riding in which case you would need to route the hose differently or do your riding in reverse. When you're sure everything is copacetic, overfill the tank, shut the lid and test ride it because it shouldn't be stalling. |
Its a common problem under specific conditions to vapor lock if you overfill. Ony happened to me twice over the yrs. Of course once was the middle of the Bklyn bridge so I had to pull the clutch, remove the ignition key, open the gas cap, relock it, replace the key and start it up while coasting at 50 in traffic (downhill side). Just made it.
So don't fill it all the way, but it doesnt even have to interupt your forward progress. |
You say you"built the bike back up", you sure you have the hoses on the petcock correct?

Actually I wouldn't worry about it too much unless it turns into a recurring issue. Mine actually did the same thing the other night and it hasn't done it in over 10 yrs.
Just topped off the tank got on the freeway and a few miles later it cut out. Did thew standard stop and open the tank and it started right back up and no issues from that time. So you either overfilled a little bit or managed to pick up a drop of water in the vent line. Which goes back to my first statement of don't worry too much about it. If it continues to happen check the vent line to make sure it has no low spots. |
