Questions for the WR450F people. I recently got a 2014 WR450F. I've been a long time YZ450F rider. I installed the Yamaha comp CDI, FMF power bomb exhaust system and opened up the air box. Now what? 1. Grey wire mod, is it still necessary and / or worth it with the new CDI? 2. Cam timing, whats your thoughts? Re-time the current exhaust cam vs switch to aftermarket (Hot Cams). I miss the YZ feel from the engine. 3. Any other worth wild mods?
