austin03 - instead of dropping a tooth up front, I went +4 on the rear sprocket (45t). I personally did not want to have the chain wrapping around a smaller radius up front.
But to answer your question, nothing explodes when you remove the slave cylinder and sprocket cover. Follow these steps, and be prepared to clean A LOT of accumulated gunk from the sprocket area:
- Squeeze the clutch lever in and lash it down with a bungee or strap
- Remove the 2 Allen bolts from the slave cylinder and pull straight out
- Remove the pushrod (remember to clean it before reinstalling)
- Remove the speed sensor from the sprocket cover
- Remove the 3 bolts from the sprocket cover (1 up top and 2 below)
- At this point a 1.75" or so spacer may drop out; save it for reinstalling - THIS GOES UNDER THE FORWARD SLAVE CYLINDER BOSS and the Allen bolt fits through it
Clean, clean, clean the area. All sorts of filth accumulates here. Kerosene is a good cleaner.
When reassembling, the cover and speed sensor are a no-brainer. When putting the slave cylinder back on, lube the push rod with a suitable grease and insert. Then run both bolts through the cylinder mounting holes and place the spacer over the foward bolt. Then you'll need to wiggle the slave cylinder into position. When tightening the bolts, snug each one a little at a time (don't honk one down then the other). Torque to comfort (I like "Guten Tite") and release device holding down the clutch lever. Cycle it a couple of times and give a test run to make sure. If you feel any binding or the clutch is not disengaging, you might have to repeat slave cylinder installation.
