I dont want to cut and paste a whole other post but we had a discusion in the gas engine forum about putting the old 62 on a diet. Mine is not sub 3lbs like a DA50 but its close. Oh yeah its a 62 and not a 50. All the info is in the other forum. (gas engines)

My 62 has had minor port work done buy a 2-stroke motorcross builder. Its been so long since I put I tach on it I'd be affraid to say exact numbers but I do remember a 200rpm increase spinning a 22x10 menz I now swing a 23x10. My 62 is 8yrs old and I will put it up against any 50 out there. .

I am really close to odering a 13-1 compression head for it from Daves motors. My only fear is making it idle rougher, every time Ive done this in the past engines always hit a little harder and shook a little more at idle. However I would'nt be suprised if that and a tuned pipe added 500+ RPM.

It deadsticks all the time though, I cant seem to get it to run without fuel. ONCE I have solved this mystery I shall post my results. Im sure others have encountered this problem with thier 62's.
