On my Raptor I have a k&n pro flow with hmf slip on tried 160/165 jets and ran bad. put the 155/160 back in and now it leaks out overflows and cuts out on the top end. The bike ran good with the 155/160 jets before we tried the bigger sizes. Any suggestions on the problem or what i need to do about it. also how many turns on the idle adjustments

 

I took mine back to the stock jets and it runs like a champ. I had the same problem and would stall with the bigger jets.
