Genuine Roughhouse NCY Transmission Kit Install

[Haystack]

I ordered the kit from Scooterworks, was here in the blink of an eye. Install went pretty smoothly. Ended up switching out the supplied 9g rollers with a 8g mix (3 x 7g, 3x 9g). 9g was too heavy and 7g was too light. The supplied variator ramp did not have the correct splines for a Roughhouse so I wasn't able to use that (must be made for a GY6 crank shaft).

I made a video if anyone's interest in how to do it yourself.

For roller weigh reference, I'm running a 70cc BBK, and Prima Pipe, modified air box (dremeled entire snorkle tube wall out) with stock carb. Other setups may vary for ideal performance.

Anyways, the scoot hauls ass. Acceleration off the line and top speed are much improved.

Just thought I'd share my experience with anyone considering the upgrade.
