Yesterday I took my 2002 R1150RTP in for her 84,000 mile service.
When I picked up the bike, the mechanic filling in for my regular mechanic provided me with a list of items soon needing attention, including the notation "throttlebodies VERY worn".
I've never heard of throttlebodies "wearing out", and a search of the Oilhead forum for "throttlebodies" and "throttle bodies" produces no relevant results. Do throttlebodies wear out over time/miles?
If the phenomena is real, and your bike had worn throttlebodies, would you insist on new parts, or would you accept used throttlebodies as replacements? New throttlebodies go for $1000 for the pair, while beemerboneyard.com has one pair available for $195 and another pair for $245.
