How can I modify my Yamaha Crux - 2008 Yamaha Crux

SOURCE: modify

I assume you want to modify the engine for better performance, i.e. a quicker, faster bike. The only thing that will really make a difference is to install a race cam. Other modifications such as a foam air filter, re-jetting the carb, running a streight pipe exhaust, gas additives and hotter spark plug are just smoke and mirrors when compaired to a race cam.

Your little 110cc can probably match a stock 150cc if you have a race cam. Yes, you will need to re-jet the carb to match what the cam puts out but re-jetting is a simple and cheap process. The custom cam will cost $200 or so. Send your cam in, they rework the cam faces and send it back. If unfamiliar with cams and cam shaft timing I suggest you have a shop do the tear-down and re-assembly.

Contact Web Cam Racing (1-951-369-5144) in California and they can fix you up. I guesstimate $200. plus shipping both ways. www.webcamshafts.com
