I haven't posted anything yet, mainly because I am in awe by the wealth of information you, I mean WE share here. Thank you most recently for fixing my bike computer. Also porting and noise reduction. I built a 66cc Grubee on a new Greenline 105 in burgundy and a 38t sprocket (I think). http://motorbicycling.com/images/smilies/rmfla.gif Thank you for all your help.
