Solved.... Thanks for the help... Full Throttle Idle without touching throttle 87K100
I just finished putting an 87k100 back together after sitting for two years after a couple of deployments and a drop from a semi trailer. Everything seems fine except when I start it, it immediately goes full throttle. I disconnected the choke thinking that could be the problem, obviously not or I wouldn't be writing. The throttle cable is properly adjusted so that it should be at idle when released (butterflies appear to close fully).
I did not do a disassembly of the engine when it was in pieces as it had just had its 10k service at the local BMW place and was deemed perfect condition, and the engine ran great after the fall from the truck. The wiring harness was removed and all connections cleaned (and hopefully put back correctly, labled everything that I saw that was connected/never connected, there were a couple of connectors that don't seem to have ever been connected with anything...). Most of the work was just replacing hoses, lube, paint/powdercoat, brakes and fluids.
Please help. I'm stuck at this point and it is the only thing holding me back from taking this pristine piece of equipment on the road again.
