Congratulations on your purchase of the most advanced and adjustable off-road clutch system available. As your about to learn, itís function and adjustment is quite simple.
Begin by installing the flywheel (a) on the crankshaft with the factory supplied collet. Next, using a 10mm deep socket, install the long clutch nut (b) . Holding the flywheel with channel-locks is helpful in getting this clutch nut very tight.
Install the shoes (c), followed by the pressure plate (d). The spring (e) is next, begin with the 1.3mm Gold spring. Apply some blue thread-locking compound to the first threads, and install the adjusting nut (f). Wipe away any excess compound.
The initial adjustment should have the adjusting nut flush with the clutch nut, (see fi gure 2).
Adjusting Shoes and Springs:
The Carbon shoe has the moderate wear and is a common first choice, it has a linear throttle feel to it, with a moderate amount of grip.
Rulon on the other hand has higher wear, this is especially dependant on the amount of slip used. It does however have the most grip. Be aware, because of this, the clutch can feel like its getting heavy (engaging early), This is because of the increase in grip because of heat. Base your adjustment on a hot clutch, 1 minute. This is an excellent choice on a high traction tracks assuming you put the time in.
Teflon has the least grip with excellent wear, it is best suited on low traction conditions or for engines lacking bottom end. It allows the engine to spool up before the clutch locks.
As mentioned begin with the soft 1.3mm gold spring. Depending on the inner-diameter of your clutchbell, the shoes should begin to engage just above idle. As you tighten the adjusting nut, 1/3rd to 1/2 turn at time, the engagement point will occur later, resulting in improved acceleration. This is because engagement is getting closer to the beginning of the powerband.
If you donít have the experience with the feel of your vehicleís acceleration, another method is by observing the exhaust smoke. The very moment you hit the throttle, smoke should be coming out. If there is hesitation, or you see no smoke for 5-10 feet, tighten the adjusting nut, the clutch is heavy (engaging too soon). If you have to tighten the adjusting nut 3mm down from flush, use the next hardest spring (dark green).
