I have a 94c on my 1980 Kawi Drifter and would like to raise the engagement rpm. It has an orange spring and 25.5 g pucks right now. It engages at about 3500, but the power kicks in at about 4800-5000 rpms. The highest I can engage it according to Dennis Kirk is about 4000 rpms with a white spring and 20 g pucks. Is it worth my $25-$30 to increase it that little? Is there anything else that I could do? Also, will it effect the overall clutching of the sled? Thanks.
