Is it my crank seals?

[PaulDalton]

I was riding my 99 blaster today (fmf full exhaust, oil injection block off) and it's been idling really high and won't really come
Down. Tried the the idle screw. And then it started blowing a little more smoke then usual. Then it stalled and wouldn't start. Waited 30 minutes and it started but was Revving high and would die shortly. Got it home and the plug was fouled. So I drained the oil (not sure why) and it had a bunch of little specs of rubber in it. So I'm thinking the starter side crank seal is the high idle culprit and the clutch side crank seal is the smoking culprit. Any and all opinions are very much appreciated. The smoke is white btw not blue

You are just going to have to do a leak down test and see, what's going on, if it is leaking out the case vent then there is a decent chance that your right side crank seal is leaking , it could also be leaking into the trans case from the crankcase side.
Leaking through the flywheel/stator side seal is a little easier as air will be leaking out from the stator cover somewhere, either way you will need to pull either the left or the right side cover if a crank seal needs replaced.
