2011 - Quick history and summary if possible.
Bike has always occasionally not started on first push of the start, you flick key off then back on once or twice and it would work (maybe do this once a weekend with dozens of starts)
2 Years ago i couldn't get it to start at all, put battery charger on it, still nothing . Kept playing with it, suddenly it started , but instantly stalled, started again , instant stall, started used throttle and was fine, but would instantly stall. Cracked gas cap and it went away and i continued on. - Back to only the occasional not starting instantly which never bothered me.
Now recently i went to start it to put it on trailer to go home and it wouldnt start at all, i figure "Oh i know what to do, ill crack the gas cap" Nope, ended up tightening up the battery terminals to get it to start, it had gotten loose somehow. But i had that stall issue and could only start it and use the gas and quickly shift to load it up.
Got it home and that problem was suddenly gone?
Using bike again this week, and now the problem is happening very consistently, so i checked my fuses, all looked good. Bike was running fine and it was idling fine. Was starting to think it was a relay or the starter going bad, but then the bike threw out a random check engine, flipped key on/off a few times and it went away for most of the day. Then it came back and is pretty consistently on now. P0520 .Bike would still start/run with the light on though. So i unplugged the oil pressure sensor and hit it with electrical contact cleaner and some compressed air. But to no avail.
Seems like i might have 2 issues going on at once now? I also tried a spare key , same occasional not starting if i turn the bike on/off for a while sitting there i can get it to not want to start.
Any idea's which direction i should go with this?
