My biggest gain was the custom cam I had ground. The grind has a 34 deg. overlap so lots of duration. The available performance cams don't come close. I also had to up the carb to a 32mm mikuni slide carb. The down side is I will use a tank of 103 octane fuel in about 2 hours of trail ridding, also when cruising my RPM's are quite high. I need to regear the final drive to bring the rpm's down and give me more top end on the long runs but I have to be careful not to sacrifice too much bottom end.
