Before this last "episode" I attempted the procedure listed above for turning it over 2 or 3 times then going till the decompression lever clicked, then let the kick lever up to top and then gave it the almighty startup kick. It backfired every single time I did that, so I quit it. Up till this it didn't backfire at all since the last bad one and it was starting reliable 1 or 2 kicks, just had that constant stumble/miss. Also the last time it did this I had just filled up with super unleade 91octane, then by draining and switching to 87 from another station, it started up again. I was running on that gas all the while till I filled up again with 91super, but at the same station that I got the 87 from.It wouldn't start after that. It couldn't possibly be that it HATES 91 octane (no ethanol), and will only run on 87(with ethanol)???? I do know the bike is running rich, black sooty plug, but I put in an iradium plug the morning before.
Is there any chance the regulator could cause the miss, due to it not missing for the first minute, then the miss starts. Also when I rode to work at 40F, it ran better(less missing/stumbling) than when the temp was warmer later in the day. Something was staying cooler and allowing it to run better.
The rich running condition wouldn't cause that much missing could it? Smaller pilot? lower the needle in the primary carb? Out of sinc carbs? It ran great under acceleration!
