Help!!! engine shooting stuff out exhaust, Picture Added

Post by Gotanubike »

When you saw your bike tipped over was there no leaked fuel on the ground??? Carbs have overflows for such scenarios at least I've had my bike on its side enough to know that lol. In any case, if the fuel managed to make its way through the intake and into the expansion chamber, it must have made its way down through the charging port into the crank area...you may have some pooled up gasoline mix down in there and it might be wise to tip the bike upside down and empty it...the only way to do that is remove the cylinder, anyways good to see you found most of it

there was a little bit on the ground, and honestly after trying my damnedest to see through the lead wall that is the sight glass ive come to the conclusion that the only sure fire method is to just split the case and make sure. after pulling the packing out of the silencer yesterday im thinking this was the bike telling me "its time"

Carb is easy on this bike, lots of folks are scared of it until they do it, then wonder what the fuss was about. Can't imagine that the bike laying on its side would have leaked that much fuel through the top end without draining through the overflows (it would have to get through the carb, past the reeds, out the exhaust port). But stranger things have happened. Burning out that mess will certainly help the bike run better.

If it were me I'd put the pipe and silencer back on and run it. It looks like the bike was laying on its side and the fuel oil mix ran into the pipe and pooled there. I'm surprised it started up for you with all that in the pipe, but it obviously did.
I bet the bike is fine. Just don't leave it laying on its side anymore!

Haha! My bike cycled an entire radiator full of coolant out the exhaust and didn't even stall...man I wish I had gotten that on film last summer haha
