  • Cylinder Works Standard Bore Cylinder Kit

    Cylinder Works Standard Bore Cylinder Kit

    Chris in WA

    Tons of Compression

    I didn't realize how much power my engine had lost until I installed this cylinder kit a few weeks ago. My DRZ is like a new bike. It sounds like a throaty 4 stroke again and is much more responsive. The kit was easy to install and reasonably priced. We'll see how it holds up long term but it looked and felt like a quality part while I was installing it.

    Just can't beat the price

    The Tusk oil change kits as well as the Tusk tools and other products have all been outstanding. This is part of the reason that RM ATV MC has gotten 90% of all of my business for power sports this past couple of months. Everything you need is in the kits, and all is top notch.
