Acerbis tank and stock Kawasaki fuel valve petcock??
 

Is anyone using the stock Kawasaki vacuum fuel valve petcock in conjunction with an Acerbis 3.7 tank??

I have forgotten to shut off the Acerbis manual fuel valve twice in the last month and filled the bottom end with gas. Not good!!! I had to drain the oil and change filter. This is the only bike I own that I must shut off the fuel valve all the rest of the bikes have vacuum operated valves. This is something that I am just not used to and I really don't want to have to shut the fuel off every time. Plus it's a pain in the ass getting to the Acerbis fuel valve to shut it off.

I have been thinking about rigging up my old stock Kawasaki fuel valve somewhere inline between the Acerbis fuel valve and the carb. Any suggestions??

Thanks!!

I seem to recall someone trying the stock petcock on the Acerbis tank. It may have been redpillar.

Sounds like you have a problem with the carb needle & seat and/or float level. It shouldn't flow like that. Time to pull the carb for a cleaning & inspection.

A float level issue has crossed my mind. I didn't really pay much attention to the float level when I re-rejetted the carb when I got back from riding in Colorado several months ago. If it is set too high it would cause the gas to get by the needle and seat.

I still would like a vaccum valve tho. :)

Both the 2009 and 2011 KLX250s I own (owned) had manual fuel petcocks, not vacuum operated. If you're flooding the cylinder with fuel then, as mentioned, you likely have a sticking float needle. Float height, I'd think, would have to be drastically off to be the culprit, but I guess could be possible.

Sorry about that guys, I forgot to mention mine is a 2006 model and it came stock with the vacuum operated fuel valve.. I do have the BB 351cc kit but, that should not make any difference.

My 2006 KLX did not come stock with the vacuum actuated petcock. My 2006 KLR650 does.
