Topic: fuel in the airbox boot

[uwjberg]

ok - so i got my bike running this morning, set the idle, and everything was running great. after 15 minutes or so of idle and tuning, the overflow tubes belched out a bit of gas, then stopped. it did this a couple of times.

i turned the bike off, and started working on something else. several minutes later, i saw gas leaking out of the boot between the carb and the airbox. when i removed the airbox, there was a small puddle in the carb on the airbox side.

what could be causing this? is it the float level? anything else i should check?

Sounds like you've got dirt in you float needle valves or they are old and not sealing properly anymore .

 yep, it's your floats. if the carbs have been dry for a while a float can hang up, give it a tap and it should stop. and always turn your petcock off. otherwise you will have to pull the carbs

Fuel flows into the airbox and boots out of the top of the bowl because the drain line hole is smaller than the inlet around the needle.  Lots of fuel in, only some can get out.  You may have clogged or restricted drain lines and tubes also.
