I have the 06 800 adrenaline. What spring are people typically putting in the primary to make engagement higher and also changing the shifting a bit. Can this be done with just a spring change, or do I need put adjustable pins and gear down. I am not sure if I need to go the whole clutch kit or not. I am simply looking for a little more humph! I guess, I'm not a lake racer! I have done a search, but seem to only find people talking about the kits. I know there needs to be another way. Just not sure what.
