Have replaced the K1100 engine in the '88 K100RSSE. Mechanically no problem.
Want to keep the K100 wire harness since it's set for ABS1 and almost all the sensors are plug and play. But the K1100 doesn't need the AFM and the TPS is now 4 pin vs 3 on the K100. Has anyone gone through this before...can't find anything in the history files.
