I'm using stage-1 kawahara camshaft. I changed my sprockets into 15-40. It's not working for me. I can hardly hit 130kph. My brother test drived it and it only reaches 122kph on the 4th gear. I'll be putting back my 14-45. It works the best for me. I can easily hit 130-135kph. Kawahara the best. No need for a valve pocket.
