Re: What kit is good for me?
i would agree an 8 speed rear hub, a shifter kit and a well modded 2 stroke would do the job. my advice would be to take it to a hot rod shop have them port and polish it for you it would not cost very much as it is a small job.
as far as exhaust goes use a good synthetic oil and it would be negligible.
Reliability... well any motor you run for hours on end is going to have problems the nice thing about the two strokes is they are inexpensive so buy 2 kits have them both modded that way if you have a failure you can be up and running in less than an hour.
Ride it like you stole
