one exhaust runs cooler

Not sure if this is related to my drivability problems though I'm sure it is. Working on the bike and ran it down the road and back, won't go over 35-40 mph, doesn't hesitate runs smooth. Got back and put my hand behind the right side exhaust and is hot(like you would expect) put my hand behind the left side and it's cool, not hardly even warm. Ahhhhh..........

Fuel, spark, compression, and timing.

Probably a dirty carb.

Wondering if you found your problem. My 99 this year started the same way.

Have you done anything for the carbs, like cleaning them or running a carb cleaning fuel additive to the gas? That would be my first step, maybe even drain the fuel from the carbs and re-fill them with straight seafoam for a day or two, then drain and see if it'll run right.

Probably stuck float or dirty carb. Seems to always be on the left side, same side the bike leans on the kickstand. Thats why I put it up on the center stand when I don’t ride for long periods.
