Have it sent right
I used for a quad bike. It worked well. Fast shipping. Here the dislike, they did not plug the carb hole or the muffler hole on intake, was full of styrofoam. Not good on their part for the sales of more and not good for customer.

Wear a helmet ...she dont play no games
So far this engine has been great ... Lots of power and it sounds an runs awesome ... Super easy to set up since smart engineers from the factory have already prepped the motor an completely buttoned up the harness so its dummy proof an all you have to do is plug in 4 little color coded wires an you got action .... This thing looks great ... love all the chrome an silver ... They always say beauty is in the eye of the beholder ... Well that guy never drove 1 of these ... This thing is scary fast the torque is unbelievable
