Ok guys and gals. I have made the commitment and ordered this lifan 100cc engine. I ordered it today and is estimated delivery is mid March. The only things im really worried about is if I have to raise the motor for clearance then i will have to manufacture a shifter linkage, which wont be too dificult. Also the fit is going to be tight so im prolly going to go to a really small bicycle front sprocket or i may have to.do away with the bicycle drive all together and just have the pedals on for looks.(I can hear it now so let me clarify: I know removing the bicycle drive woukd then not be a "legal" mb. But neither is 100cc engine and in most states the law is 49cc or less so If the cops really wanted to enforce it all these "66cc or 80cc" motors would not be legal either. The point is the cops in my town don't really care as long as your not obstructing traffic or speeding through town or being dumb and doing burn outs or wheelies through town. If my measurement are correct it should just barely fit. May have to do a few mods but it ahouldnt be too difficult. I was looking into big bore kits/chainsaw kits but in the end they were too much hastle and down time with no bike that swayed my decision. And these lifan motors are pretty well reviewed. Its like main motor company for motorcycles/mopeds overseas. So....that being said if anybody would like to buy my old motor here in the next couple months it will be for sale. Its a Fred (cr machine ) built pk80 race engine with less than 20 hours on it. I will be selling the engine only (with the fred head, and runtung performance carb) for $250 ive had it gps spees tested at 43 mph on flatland. If you lookin his site he gets $375 for them. Heres what the ebay artical said about the Chosen model: standard. Below are some pictures of the motor and the kit that comes with it. I have a 21mm oko copy carb so I'll probably be using it instead of the 19mm I believe the kit comes with. Also might swap out my aluminum mag rims for a set of small go ped tires or find some good 10ga. Spoked wheels with a billet hub adapter for the sprocket. I don't think that the cheap mag wheels will hold up to repeated torque like that. Onenof my buddies had a modified 4 stroke bike and he twisted his rear wheel to s**t. I will keep y'all up to date on all my progress and take plenty of pics of the build and when finished yes I will post a few speed runs and going through the gears. I saw online that this motors top speed is around 140km which is around 75-80 mph I believe. I will never need to go that fast so I'll prolly gear it down so i can take off in second from a dead stop. Any input or ideas are welcome. I nees all the help i can get anyone else try anything similar? And please I don't need comments like why not just get a full on motorbike? Or your going to kill yourself. No bashing please, I am an experienced rider and I raced motocross all through my youth and have had 2 full size bije in my life so i know whats safe and not. Like I said I dont plan on going 80 mph but it will be fun for One and for two if I have to get on a 2 lane highway for some reason, I know.the power is there if I need it. Otherwise it's just going to be a conversation starter and a brag build.
