#1 Valves hitting piston after rebuild06-23-2013, 11:42 PM
Timing is 100% spot on, all I did was fit +1mm lift cams and a 156c big bore kit, I tried turning it over by hand and I can hear the valves hitting the piston, someone on another forum said he came across the same problem with the big bore kit. As he was the person that pre-warned me about the new wrist pin being bigger, which was bored out to accomdate it.
Anyone have any ideas on anything that can be done, such as maybe a spacer/wider gasket as timing isn't the issue.
Any help is appreciated.Lexmoto XTR-S 156FMI (156cc big bore) - 163FML Cams (+1mm lift) - Foam Filter - Sports Exhaust - 17T Sprocket - 110 Main Jet - PZ30 Carb - Aprillia RS Ignition Coil - Casoli CDI
