This is only my second post on here. I am a little shy when it comes to posting. I have a basic understanding as to what the different primary springs do, and what different flyweights do. However, the secondary springs, I need some schooling on. I hope that someone can shed some light on what differences to expect from a stock 140-240, vs a 155-222 etc.. More specifically which number changes what. Thanks.
The first number is the begining spring "Rate" and the second number is the ending spring "Rate". This spring causes the secondary clutch to resist opening (upshift) and encourage closing (downshift). It also is what puts side pressure on the belt to prevent slipping. It works in conjunction with the drive clutch. The spring is only a portion of driven clutch tuning. The other big item is the helix (angle).
