Strange Happenings
« on: August 14, 2010, 05:19:07 AM »
Hi,

My 2007 p250 has been acting strange lately. It usually runs just great expect just after I fill it up with gas. Then it won't idle for a short while, especially when it's hot. After it cools down it runs just fine until it needs to be filled with gas again. Any ideas on what's happening?

Thanks in advance

Vapor lock.

Here's how to test: Open the fuel cap, and continue riding. If that takes care of it within a few minutes, it's vapor lock.

Solution: Clean the vent.

 Hubby had the same issue.  Took springs out of the gas cap.....and violet!  It was not getting enough air....hence vapor locking?

Hi,

If you take the four springs out of the gas cap, will that prevent the cap from sealing and allow gas vapors to leak out. If these spring were replaced with ones with less tension, would that work better?


Thanks

This would probably require Swiss watch mechanics specialist and would exceed scoot`s remaining value. :)

...OR you could clean the vent and let the engineered item work as engineered...  Just an idea.

That's why I said I may have to stop answering this one. Why bother if people aren't going to try and report back success or failure?

No one who's described the problem has mentioned whether or not my suggestion worked for them. It's a little frustrating.

Thank YOU for reporting back!  I bet I've answered this question a dozen times here this summer (not all on the P250 board, of course), and you're the first to say, "Yeah, that was it!"  :)
