Re: What is the best place to get a 4 stroke kit?
I really have no input on where to buy one from, but if I were to build a 4 stroke bike for someone else, I would definitely be concerned with reliability. One of the 79cc predator engines would make a great candidate for that purpose. They seem fairly reliable to me. I do keep looking at huasheng engines, but I've seen some disasters from those things that kind of scare me away.
Having no experience first hand with using a 4 stroke bicycle kit, I really don't have a leg to stand on when I say this. I have, however, been investigating the same thing for the same reason, and all roads seem to point to the HF 79.
