Adjustable Ignition Advancer
To make your own ignition advancer is easy and it's FREE.
Step 1: Remove the lower fairing and front/right engine cover.
Step 2: Remove the rotor by removing the bolt in the center with a 6mm hexagon wrench.
Step 3: Remove the 3 screws holding the ignition plate and loosen the plate.
Step 4: Enlarge the bolt holes in clockwise direction.
Step 5: Reinstall the plate and rotor (rotor bolt torque 25-34Nm 18-25.5lbft).
Step 6: Twist the plate in counterclockwise direction and tighten the 3 screws.
Step 7: Reinstall the engine cover and fairing.
Step 8: Go for a testride.

So, how much should you enlarge the holes and twist the plate? Well the advance should be 3-5° and 1° is almost exactly 1mm on the edge of the plate. So enlarge the holes about 5mm. The best way to find the optimum setting is to dynotest the bike and try different settings. The advance units you can buy have usually a fixed setting of 5°. Be weary carefully not to over do it and listen for engine "pre detonation" which usually occurs at low RPM, high gear and high load. On an otherwise low tuned engine you could expect about 1-2 Hp in the midrange.
Adjustable Cam Sprockets
Well the deal is the same here, just enlarge the holes. The material is quite soft so its easily done by hand. You should enlarge the holes about 5mm in each direction. Way to do it in each direction? That's because when you have assembled the hole thing you almost certainly discover you have enlarged them in the wrong direction so do both directions. DON'T forget to loctite the bolts holding the sprockets when reassemble, you don't wana lose these. Why then you ask? Well if you skim the head the camshafts moves closer to the crankshaft and the cam chain gets a little "longer" so to say. The extra slack is reduced by the cam chain tensioner but that causes the cams to "twist" in relation to the crank so the timing gets screwed up. To restore it you must twist the sprockets on the cams. You can also use adjustable or slotted sprockets to "move around" the HP and Torque peeks of the engine that is however a much more advanced exercise which requires a little experience.
