Just released from Revolution Performance for 2015-2018 106mm Indian Scout motorcycles

From their site:

1300cc (79″) Big Bore Service Kit comes with:

    • Overbore cylinder service and powder coating to orginal finish
    • Larger bore cylinders. We turn your 99mm cylinders to 106mm
    • Forged 10.9:1 compression ratio flat-top pistons
    • Cometic head and base gasket kit

Revolution Performance and Millennium Technologies have an amazing relationship with Polaris as a supplier for production and racing cylinders. As a technical partner on the Project Pikes Peak racer and Jared Mees’s Double AFT Championship winning Scout FTR750, we have a ton of experience making Scouts go fast.

We bore the stock cylinders from 99mm to 106mm and use our proprietary Nickel Silicon Carbide plating process. This yields a new displacement of 1294cc (79”) and power and torque gains of almost 30%. These amazing power numbers are with the big bore kit only. No other internal mods.
