Yamaha wr 426 hotcam
Posted October 30, 2014 - 09:08 AM
I'm wondering if it's worth fitting a stage 1 exhaust hot cam to my wr?
Apart from the auto decompression will there be any power gains ?
Also will I need to re shim the valves ?
Appreciate any help

I just did this over the summer. This was my feelings after the work was done. http://www.thumperta...-make-me-smile/
Always check and re-shim your valves if you change any parts on the top end. Quick and easy to do, whereas damaging the top is expensive and time consuming to fix.
