this engine took me 7000 miles across america and then blew up. Lifan is the largest engine manufacturer for those who are doubting the quality.

Thanks very much it arrived like days early so delivery was very fast, this was the best engine I could think of to use for my style of build so thanks a lot for having this option as an option that was available. I went with this engine because of the centrifugal clutch being automatic but still having four manual gears as a manual, plus I can add a radiator and stuff, a lot of four strokes have less than 4krpm so that means weak torque and this one has 7.5k which is stronger, it's pricey but it will be greater and more reliable than the common two and four strokes.

Unit appears to be well made but the engine mounts are a full inch in both directions too short. It might be possible to cut and weld the CT 90 frame but the bike is registered and titled and is too valuable to make it into a "cut and patch" project. The bolt holes in the mounts are also not large enough for the original sized CT 90 bolts to fit. If it fit the CT 90 frame I could use a smaller bolts and make some bushings for frame holes. The description on Amazon made it appear the unit was a reasonably simple bolt up install.Oh yeah the stock or the 3 other carbs I have that work on the CT 90 frame will not clear the down tube. I made an alum bushed 3d printed ABS bushing to move the carb forward to clear he frame which I thought was the only mod necessary until I tried to bolt the engine to the Frame....NOT happy.
