Big bore fun for your Kaw AR50 little motorcycle.

disappointing to say the least. myself and 3 others all ran this kit and soft seized on the first run or a few minutes into tuning. the bore is a few thousandths out of round. if you're set on buying this kit you'll NEED to have a boring bar ran through it and will need to machine a stock head to match. Don't even bother, find an autisa or get your stock cyl bored over.
