I'm considering upgrading to 103 with 255 cam, leaving the heads alone. I always prefer to do my own wrenching and have never had problems building engines or transmission. Am I kidding myself on this project since I have never dove into a new 96 engine? I have the SE tuner system and I assume can find a map that matches this combo close enough to allow a break in period before taking it to a dyno. Right now the bike has SE air and Rush slip on's. Rest is all stock. What should I expect from that cam, smooth idle like stock or is it going to lope on idle. Should a higher idle be used with this cam and also is there really a need for compression release with this cam? Thanks in advance for the help.
