Don’t buy
Motor won’t shift into gear. Contacted company there not trying to resolve the issue. That’s way to much money to spend on something that don’t work right

Need there wire harness to fire engine
It would be nice to know that I needed to buy their wire harness to get the engine fire tried using my old CDI box and coil pack still did not work. Now I bought their wire harness so I can use their CDI box and coil pack.
