Someone mentioned the parts needed to remove air injection. I can't figure out the right search words but I remember them saying to use R1100GS oil drainplugs for the heads and airhead flywheel inspection plugs for the airbox. Is this right?
Here's what you typically need. I think this was one of snowbums posts on the airhead email list. JT Go to your local dealer and get the following BMW part numbers: 2 head plugs (actually oil drain plugs for R11 series) BMW# 07 11 9 919 117 2 crush washers (for the above plugs) BMW# 07 11 9 963 252 2 vacuum screws for the carb BMW# 11 11 1 744 327 2 timing plugs (for the airbox) BMW# 13 11 1 259 869 Removes the guesswork and experimentation.! You need two 16 mm oil drain plugs (BMW -not sure which models) use lots of antiseize paste, two timing light rubber plugs for the airbox. two screws for the carb vacuum lines or use one inch of vacuum hose and put a short screw in it to plug it up. There are also some rubber tips around that may work. You may need to richen your mixture 1/8 turn out or so if you get more trailing throttle burbling. (Tech term)
