i think it ruined the piston and sleeve because when it gets hot it gets really hot and the engine shuts off even though its still got 1/4 of a tank of gas left. and this is what happened to my old stock ofna engine with the same airfilter so i think this airfilter is junk. i can get a new piston and sleeve off ebay for 38.00 though so i think im gonna get that and a new airfilter and then save up more for a pipe again.

Thanks
