Selling a Polaris Pro RK-Tek 858 kit.
The top end has near a total of 800 miles on it since new. These big bore kits create impressive engine power and significant engine throttle response on pump gas.
I installed a new set of pistons in the motor after 300-400 miles when switching out a new set of 13.5:1 domes from 14:1 domes. This was done solely to assure me I could safely run pump fuel without detonation. There was no damage or excessive wear on the old set so they can be used as spares if needed.
This 858 kit comes with the following:
Pro 858 cylinder, spacer plate, cylinder bolts, and power valve spacers
13.5:1 & 14:1 Cylinder Domes and Head
Boon Docker fuel controller
**Price is $1700 for motor package**
Please PM with questions or inquire as I don't follow the forum daily!!!
