I got a new stock spring for secondary only, got new sliding sheave with new ramps. The backside with numbers I set at '2' and the other side set at 'B'. Before I did anything, it ran fine, but now it winds up and screams till about 10 or 15 mph, then kicks down. Before, it would kick down at 30 and I would use a lot less fuel. I want to set it at the most fuel efficient setting, while not having it scream in the low end. If the stock setting is the best of both worlds-power and fuel efficiency, that's what I would do. I just don't know the setting.
I'm not a yamaha expert but if you like I could take a look

All clutches do the same thing you just got differnt styles of doing it.
