Use the penetrant of choice from the suggestions. Leave plugs out and let sit for minimum of 2 weeks. Remove drive chain. Using 1st gear, Use HD impact driver on countershaft nut. you will have to rotate the engine backwards or the nut will loosen up. Someone chime in if turning backwards is a dumb idea.Current Rides: 82 GS1100E, 00 Triumph 955 Speed Triple:twistedevil:, 03 Kawasaki ZRX1200, 01 Honda GL1800, '15 Kawasaki 1000 Versys

I wonder if getting some schedule 40 electrical pvc pipe slightly smaller than the bore diameter & some steel angle iron or box tubing wide enough to strap heavy duty ratchet straps on each side of 1-4 cylinders & another angle iron/box piece below frame with wood shims between frame rails & oil pan. Cut the pvc pipe into 1/2" rounds over 2-3 cylinders to start (assuming 2-3 or more stuck than 1-4), crank ratchet straps to more than snug & work the bolt on end of crankshaft in the proper direction to push the pistons down from TDC. Or 2 all-threads with bolts on each end, drilled thru angle iron or box. Maybe a second set of hands to do ratchets while one works the crankshaft bolt.
Have no idea if this would work, just a thoughtLast edited by Carter Turk; 02-02-2024, 04:34 PM.GS\'s since 1982: 55OMZ, 550ES, 750ET, (2) 1100ET\'s, 1100S, 1150ES. Current ride is an 83 Katana. Wifes bike is an 84 GS 1150ES
