How much are you guys leaning out the factory jets? I generally do .97 x stock for my elevation (7K), but if y'all at lower elevations are already knocking it down I figure I need to go leaner. My dealer doesn't have them and I don't want to buy a bunch at $5/pop + shipping that wont get used. Please advise what you have done.

Stock pipe
Boyseen power reeds
Restrictors removed
Uni air filter
Bolt in stock pipe removed...

Currently it is super rich...

 

I'd go back to stock. (92.5)

 

It is currently setup with the stock 92.5 and 20.

 

You can try a 90 main. Some think it helps.
I take it you are using the oil injection. They can smoke. Jetting won't help that.
Other than smoke, how does it run?

 

Plug chops reveal a black plug. Yes, using the oil pump.
The major issue is that if you can't get it to fire quickly, it fouls the plug/ floods. When the plug is clean it fires on first pull and has great compression.
I'm fine with running premix if you think it would help this situation. Is the proper removal of the pump as easy of unscrewing and removing the pump and blocking off the vacuum port on the carb, or does an internal gear need to be removed as well?

 

I think it will help. Altho it won't help a flooding problem as you suggest you have.
You can remove the gear thing on the clutch cover then when in to do clutch maint (you do clutch maint, right?!) you leave off the lil black plastic piece off the end of the crankshaft.
I like a good synthetic oil at 32:1
