Our Comer K80 engines are the best!

Check the IKF and WKA results in the Junior 1 and Cadet classes and you will see, MCR is on top!

Attention to detail matters!

To build a great Comer K80 engine you need great attention to detail. Every little thing counts, as these engines have very low horsepower. Reducing parasitic drag is very important in these motors we pay very close attention in this area. We straighten the connecting rods to ensure that they are 100% perfectly straight and we work very hard on the bottom end to ensure that everything is aligned perfectly. This tedious work takes a great deal of time and no two engines are alike.

Other engine builders do not spend this time on their K80 motors! No doubt!


We pride ourselves in our craftsmanship, and motors such as the K80 and Yamaha KT100 really respond to this attention to detail.

We can deliver a brand new motor or rebuild your current motor, just give us a call and let us know what you want!
