Higher letter/number on a stock yamaha is higher tension. It would go A1, A2, A3, B1, B2, B3, C1......

The higher number just makes it have to rotate more (more tension) to get on the next set of ramps and go together.

B4 is a medium setting that lets it backshift some but keeps rpm lower at cruise. Higher setting will make the engine rev more at part throttle and have more response. Lower setting will let rpm go lower at part throttle. However with a larger torque engine like a twin it has more torque at low rpm, that why they sometimes like a lower setting of B1 B2 to use that low rpm power. If you put an ATV engine in that liked to rev more, then you might want C2 or something to keep rpm higher. That engine would bog at low rpm. I have my clone at C2 or something right now it does not like to go under 2500 when riding around because of high compression, it will knock if it goes too low. I also have a 94c so don't compare that to stock clutches.
