Canister vent lines?
First of all I bought an R1100R only 1000 miles ago. I posted here with ride-ability somewhat like these two. Several things were wrong with my bike but one has risen to the top in my mind. The vent lines were reversed prior to my ownership. When the solenoid opened the canister to throttle bodies vent line, overly rich gas/air entered the TB's and the bike ran like cr@p. After a few cycles of this the catalyst was fouled, the bike would not run well even when the solenoid was closed (is the fuel tank overfill vent open to air so the mixture was leaned when the solenoid is closed?). Reversing the lines (the ex MaxBMW tech new enough to check this and several posters here suggested unplugging the wires to the solenoid to prevent it opening) fixed part of the problem. I deleted the canister, routed the vent lines to air and plugged the vent inlets in the TB's This reversing is so easy to check it should be a part of any run-ability suggestion. I don't advocate the canister-ectomy but mine was fouled. Others have told me theirs fell off! Be kind I'm new.
