A stock 3-speed with a healthy motor should top 40mph. Something's amiss if the bike won't break into the 40s. That assumes that you've got the carb dialed-in, your exhaust isn't choked-off and that you at least lapped the valves & checked for proper sealing.

You get a lot for 300 bucks.Īll else being equal, I'd expect to see 45mph from a basic 88cc kit. The power is very nice and I'm having a lot of fun with it.īottom line. Over the last month I've managed to build my Lifan to a 145cc along with some porting,Crower race cam, 26mm carb and a valve job. Parts are also pretty easy to get for these Lifans. You'll have to change out the 6v bulbs to the 12v bulbs which are available.

sells wiring kits that will help in the process of hooking up all the electrical but I've found that buying an aftermarket Chinese wiring harness will make your conversion much easier. You're on your own when it comes to your controls and wiring the 12v engine with it's CDI into the 6v system found on the early CTs. The engine fits right into the CT70 frame, it's two bolts. I do however think that his HP rating is a bit optimistic, nine or ten HP is probably more like it. The reason for the 'it should fit' comment is because on ebay you're dealing with a lot of variables with different bikes and from what I get from it he's just covering his bases. To me, the description in the ebay auction is pretty straight forward, he tells you exactly what you get. I went into it thinking I'll just run it over the summer and junk it when I wore out, the motor never quit running stong. I've put on over 1200 miles of nothing short of abuse on this little engine,pure fourth gear street abuse, the stock engine will take your CT over 60mph with proper gearing. Hey Dean, I've had my Lifan 120 for quite a while, I also bought it from the same guy 'Legendmoto', they're actually considered 120cc's (52.4 X 55.5).
