crankshaft confusion

[Matt B]

ok. trying to stop the confusion. have done a search for this and although found many answers...not one clear cut definite answer. When did the gs1100e get a one piece crank? how do i know what crank is in my motor? will they interchange?
Mine is an 81........not positive the motor is though. Where do i find a list that says when my motor was built? We need a list like the cb750 has for build dates and motor upgrade dates.

GS 1100 had roller crank bearings, it can't be a one piece crank. Some of them were welded.
1980 - 1982 GS 750 had split bearings like a car engine, so a one piece crank is possible.
Much cheaper to build that way.

Don'tremember any gs 1100 with a one piece crank. The next generation (GSXR's ) had them, I think.

Hey Matt,

I nominate you as the builder of this list. Tons of info in the archives. Let us know if you have any questions.

The GS1100E never had a one piece crank.. Late 82 they started to weld the journels
