Hey guys, I am going to be toneing down my bike and wanted to get some opinions on a cam choice. I am sick of the valve train noise. So I am looking for a cam that is quite. Right now my bike a Tman stage 4 kit with 10.5 comp. and the 662-2 cams. I was thinking of putting in new pistons and rings to freashen it up so I was going to order 10:1 pistons. I am changing the exhaust to the stock pipes with a fullsac true duals kit with 2" muffler cores. I will be keeping my Tb (HBI 55mm) Let me know your thoughts. Thanks
hmmm... I have T Man 662-1 cams in my 120r motor and have no valve train noise. T Man 662-2 cams are quite similar to my cams. I doubt the cams are the source of your noise. Perhaps piston slap?
