Some updates,
With all the fun on the dyno, coupled with numerous blasts on the street with 4 passengers (yes, people visit and ask for rides), the previous single disk clutch gave up the ghost. Now bare in mind that the Action 2MS is an excellent clutch for setups 600whp and lower, even in relatively heavy vehicles like our "full passengered" Bisimoto wagon.
Spec clutch came to the rescue with an amazing, and lightweight, twin disk clutch assembly, specifically manufactured for the D-series.
The construction is superb, the disks are made of a ceramic matrix, and of solid hub design. The attention to detail allows ease of installation (stickers like "flywheel side" and "clutch side" help the DIYer during install), and the steel flywheel is also appropriately lightened, which I simply love.
Eight pound flywheel...yes!!!
So, I removed the 2MS as she gave all she could:
Not so bad after tons of power runs on the Dynapack, and over 32 full throttle joyrides with friends and customers:
Weight comparisions. I would take a 2 pound rotating mass advantage, any day of the week!
Ready for installation:
In there!:
The kit came with specialized bolts for the flywheel and pressure plate. It is so cool to depress the pedal and hear the soft twin disk "chime" that is associated with multi-disk assemblies. The pedal pressure is not bad at all, and akin to heavy duty single diaphrams. After 500 miles of break in, the clutch assembly hooks like no tomorrow. Now, lack of traction is my friend...again.
I cannot wait to go to the track to test this vehicle out. Only if my busy schedule permits.
