Alright, after many hours of searching and reading about engines, I still have no idea which kit to start with. I am looking to ride only about 8 mile per day over moderate hills. I am 175lbs. and will be adding this to an older 26" ten speed. As a farmer and a hot rodder, I am willing to do some deburring and port matching etc. What about the 2 piece cranks vs. 1 piece, how do you know what you are getting. For what I am looking for should I just buy some cheapy e-bay kit or spend the extra $50- on something better? Add to that the free shipping vs. $20 and up. Suddenly the affordable transportation can get quite pricey. The upgrades can all come later I just want to get on the road. Thoughts?
