Requires a bit of modifying to get this to work. I used 1" square tube to lift the engine to make room. I had to order a 5/8" to 3/4" crankshaft adapter and cut it to fit. I had to cut down some of the ribs on the back plate so it would sit flush to the motor. I also needed a new bolt for the crankshaft pully because the old one is too short and the new one is for a 3/4" crankshaft (too fat).I did a lot of head scratching to get this to work, nothing seemed to quite fit, but I think I could knock this out in half the time now that I know what is need to make this work.Overall, this thing turn my Coleman BT200X into a beast. Everything about it is better. Low end power is probably double and has no problem hauling my fat ass up my steep hill. The stock clutch burned out trying to do that lol. I don't have much flat here, but I expect the speed is 30-31mph. On a slight uphill slope my GPS tells me 28mph and on the way back down it is 33mph, so flat top speed should be about 30.5mph. Totally worth the price and effort.
