i have an 02 raptor 660 that doesn’t seem to want to idle or run right with out the choke on. the bike has the parking break blocked off with a closed air box stock pipe and 686 kit with an 11:1 piston. i need some advice on what jets to run if anyone has any advice it would be greatly appreciated. thanks !

I think you're in the wrong category. Anyway....

You should have 25 pilot jets and stock jets otherwise.

BUT, your problem may be the carbs need cleaning. Run a small copper wire thru all carb orifices followed by a spray cleaner.
