at all. Another cable enters the distribution box from the start lever. When

actuated, this cable pulls a tab across that contacts a flange on the wheel,

opening the throttles a prescribed amount for starting.

So the cable at each throttle body is just that, the throttle cable for that particular

side. It is essentially as if the throttle cable has a "Y" upstream as the older Rs

did.

To do the TPS procedure loosen the free play adjusters on each throttle body.

Then do everything else the same as far as TPS adjustment with the left TB

plate closed up. When the TPS is "zero=zero", adjust the left throttle stopscrew

for the .370 prescribed. Then start the engine as described and adjust the right

TB stop screw for equal mercury. Then adjust the left TB cable for about .5mm

free play and synch the right TB to the left using the right TB cable free play

adjuster. Finalize your idle speed and synch with the previously closed bypass

screws. You're done!

Advanced Ignition Timing - Rob Lentini

Most manufacturers set the ignition timing for the typical vehicle with poor fuel

quality in mind. Modest performance gains may be achieved by REASONABLE

increases in initial advance. Just like my K75S, the R1100 is no exception.

Assuming you are NOT experiencing ANY pinging or detonation, you can easily

advance the ignition timing by about 3 degrees. Here's how to do it:

- Remove the small rubber timing hole cover on the clutch bellhousing (just

inside the right throttle body).

- Remove the black cover on the front of the engine. This covers the alternator

drive pulleys/belt.

- Notice on the lower (crankshaft) pulley that the three timing plate securing

screws are exposed, and that the timing plate (which the Hall transmitters are

mounted on) can slide CW and CCW in three slotted holes.

- Put the tranny in 5th gear and, while observing the flywheel with a good

flashlight, move the rear wheel to rotate the engine. You will be looking for "OT"

(top dead center), "Z" (full advance) and "S" (the 6 degree initial advance mark).

- Warm the engine and observe, with a timing light, where initial advance is

taking place. With the engine at 1000 RPM or less, the advance will be very

close to "S". Turn off the motor, loosen the three screws holding the Hall

transmitter plate, and tap the plate in a CCW direction from the front to the end

of slot travel. Tighten down the three screws and recheck the timing. Be SURE
