I'm working on my 103 (malossi case, 21, phgb, 70 kit, multivar Var w/ stock clutch) and have already taken 3 balls out of the clutch but want to put on some stronger clutch springs, the bottom end is still terrible (standard var weights still too). I've seen several people make mention of 2 spring and 4 spring setups. Are you doubling up two stock springs on each side of the clutch? is there compatibility between vespa piaggio malossi clutch springs, or derbi clutch springs an the stock Pug clutch? Anyone made their own higher tension springs?
Thanks!
