Yeah it has a leak wher the engine connects to tho mounting plate, but it’s an easy fix, I bought the 26” low rider bent forks and this thing tops out at 37mph, it rides like a Cadillac I love it…

Missing bearings that were supposed to come with kit. Missing the spacers for mounting bracket. Had to create my own. Without the spacers, mounting bolts could not be properly torqued. Would cause clutch to be too tight and if left loose, oil sprays everywhere. Do a better job of quality checking your items before you sell/ship them. Chain is also garbage. I had 3 different links fall apart on 1st day of use.

So my question is..most 2 stroke engines spin to the right side if fan cover is facing you,so if you install it,wont it make the bike wheel spin in reverse? Or is that why they include that gearbox with the kit?

They put in a throttle cable meant for a center frame engine mount. It was too short to reach the rear wheel engine mount. Had to order a longer cable to make it work.
