  • Things to look out for

    I have wanted one of these kits for quite some time and finally got up enough nerve to pull the trigger. I was excited when it showed up on my porch just a few days later. Upon opening the box, it was quite evident that some of the parts and hardware were clearly sub standard. I made a list and went to the hardware store to get replacement nuts, bolts and washers. I pulled the side cover off only to see the edge of the larger pulley rubbing on the clutch bell. The pulley is not square to the hole in the pulley and it therefore wobbles. VAlso the hole that was machined for the jackshaft bearings was too large for the bearing allowing the shaft and sprocket to wander and jerk around. Since the rear pulley is not in alignment with the output shaft, the front edge of the jackshaft bearing carrier had to be spaced away from the aluminum Plate by .030". It'll get it figured out probably but it has been a disappointing journey so far. Lots of disappointment in such a small Package. Buy at you own risk! (Don't we always)?

  • 4 cycle vs 2 cycle.....

    1 have used 4 of the 80cc 2 cycle motors on bikes and this is my first 4 cycle to use....it is far better motor....easy start, more pulling power, and no mixing oil/gas....personally i think it is worth the difference in price....

  • Fun

    I built one of these before and this was definitely a better kit. It is not very difficult at all and you really need very very few modifications just a great product.
