Running rich

99 R1100R. Remus exhaust, no O2 sensor, beige Cat Code plug, CO pot. Motronic
reset after modifications.

The right cylinder's spark plug is consistantly sootier than the left 
(which
looks OK). I assume the bike is running rich on one cylinder (the right 
one,
sitting on the bike).

(A sidebar: this is the cylinder that broke a piston ring late last 
year. I
suspect there is a connection between that and the rich mixture. 
Unburnt fuel
blowing by the rings and diluting the oil?)

Where should I start? TPS 0=0? Fuel injector? Would an aftermarket chip 
be of
any use? The bike has had all the usual tune-ups performed--valves, TB 
sync.

Thanks

Pieter
