got back from a trackday and when taking apart the exhaust i poured about a cup of fuel out of the right exhaust chamber. the left exhaust chamber was dry. what does this mean? i know for a fact that the fuel tap was in the off position and the bike ran fine at the track with plenty of power. whats going on? thanks

Even though the tap was off, it doesn't mean that the float needle hadn't stuck previously and allowed the carb to overflow and drain into the chamber. It can take a while for fuel in an expansion chamber to evaporate, so could've been in there for a while.

You'd need to either be running huge carbs and jets and have a misfire or poor starting on one cylinder, or have a stuck float valve to fill the chamber up really. Think about it logically... there's only one place the fuel can come from... the carb! If the tap doesn't leak, then it must be a float level/valve issue or it's not burning all the fuel you are feeding into the crankcases.

a stuck float could do that. a few months back i a had trouble starting my 18. apparently i forgot to turn off the tap and with a stuck float it filled the the expansion chamber with fuel. when it did finally fired up, i reved it up and sprayed fuel all over the garage! was lucky didnt ignite!
