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.Read All Reviews

Expensive engine mod but if you are serious about powering up your YZ grab this and get to the front. Need to use VP u4.4 but you should already be using that if your racing at all . Be sure to set the new mapping to the ECU !Read All Reviews
