Gees a thread with my name, hard to miss.
I don't want to make a lot of claims about the weight because they are just another tool in clutch tuning. I did much the same as you except the opposite went from 62 BB's to 64's. Also tried a bunch of helix, spring combinations and several Polaris weights. What I "thought" I needed wasn't available in a weight. I needed heavier weights on low end, but they were too heavy mid & up. Light weights worked great in hardpack but trenched in soft snow. Lighter weights also seem to realease slow so that there is an "engine braking effect". If you let off the throttle abruptly, it's like you slammed on the brakes.
So I started customizing weights by changing the location of the mass until I found the sweet spot.
The result exceeded my expectations-a lot.
So just for fun I am building a few sets for others to try. The concept seems to work at different altitudes and with different mods-stock, single pipe, single pipe/ported. The clutching seems more forgiving of altitude changes and snow conditions. My fuel economy and oil consumption improved dramatically overnight. This is starting to sound like a lot of BS but that's my honest opinion and results.
At present I have the equivalent of 58, 60, 62, 64 & 66 gram weights-will probably add some 68 & 70's pending results at lower altitudes. The profile of the weight is unchanged, just the "mass" moves. I decided to call them
Big*Torque weights because they get the CFI engine torque to the track. I'll PM you some addl. info.
