Hi all, Iíve been riding my new to me 250 for about a week now, some quick history: it sat for a year and a half before I bought it. 5200 miles on the clock. I drained the fuel that was in there and installed a new agm battery and new oem air filter. Has been running great but died immediately a few times on cold start up (A quick blip of the throttle after light off fixed that). Topped off the gas(91 octane) way too high Monday morning, didnít spill out but was maybe an inch from the top. Went to work and back, about 30 mins of total riding, no issues. Monday afternoon I removed and cleaned the throttle body and idle passage. Started up great, rode to work this morning, no issues, rode back a few hours later(Ambient temp around 90 in Florida) and the engine was bogging randomly when Iíd whack the throttle. Idles great, seemed fine if I slowly rolled it up to speed. My gas gauge is still a little past full. Pulled the gas cap off and it made a pfffffft noise.
Iíve read a few posts on driveability issues after an overfill related to the evap canister. My question is, if that is a potential culprit, will it go away as the fuel draws down or do I need to do something proactive like drain the evap can or something.
Thanks for reading!
