On my newly acquired 1998 k1200 RS (98kmiles) the bike starts and runs but if I rev it to 2000rpm and hold there, the engine revs will dip down to 1500 and back up to 2000 again on it's own. I hold the throttle still and the revs fluctuate, which translates into not being able to roll away with low revs, I have to race the engine and slip the clutch to get going.

I was told this is a failed TPS. Does this sound right?

The bike had been sitting for 6 years prior to me getting it running 3 days ago.

thanks
