hit ebay get a Lifan 125cc complete set up. carb cables shifter kick starter cdi coil and pretty much everything you need. the only prob i ran into was the carb was hitting the tank. My fix was to cut the bottom flange off the and remove 1/4 inch and then took it to my welder and had it re tig welded. hit it with new paint. and looked new. if you would like to see a pic let me know and I will post on to my album. I would go with a lifan no doubt best deal for the money ...

Heres a big one, Mad 70s in action ,I bumped it up so it will be easy to find, if you find a motor one of us probly has it on one of ours, 125cc is great for overall power and durable, 140cc makes more and still is not to pricey, 150cc and up will give you alot more power but a pain sometimes, I us alot of Pirahna stuff [wholesale-cycle] myself,Dr atv is a good source also :cool:

contact my friend steve for a great deal on a 110cc engine. the 125 has about .5 to 1hp more than the 110 but usually the gearing in the 110cc make them faster about 80% of the time.

I just ordered a 125cc lifan, $273 free shipping to lower 48. carb, kickstart, shifter. i did a ton of research, I think its a good choice, you can put a $50 pitbike muffler on it (ebay) so for $325 total, your set. (at least thats my plan!)
