Maybe one of your members might be able to help me. I bought a used 125CC Honda Tracfour for my grandson and I need to know the timing spec's for engine valve train and ignition system. Any information can be forwarded to my email site. Unit was running but at higher end of rpm's it was very rough. Cleaned the tank and carb of all forgin materials but this did not help. Unit is now only firing once in a while but will not run. I think it has jumped time. I have experince with Honda motors but it has been years sence I have worked on a 125 motor. Upon inspection of the cam timing marks I find that the cam is about 30 deg's from what I remember it should be at, but I am not positive on mark alginment. Can anyone help.

Thanks for the help
