Righteo, clutch springs were too light for my exhaust, put the mid strength ones in, it pulls off ok, revs seem fine, slightly low maybe.. BUT... after 5 minuites of just going round the street, it gets worse, the clutch biting point lowers. not sure if.. 1) they're too strong and are causing it to not full engage which is overheating the clutch, likely possibility as it gets worse as it gets warm. 2) they're too light and i should use the strongest ones as the clutch is biting too early when it gets to operating temparature. anything im missing? once the clutch is on, the rollers kicks in and it take off.
again, transmission and fueling can often be confused.. check the idle mix (too rich/lean when warm will cause it to be poor off the line/when reapplying the throttle)
