gs 1100 crank in a gs 1000

[48woody]

Hello; thought I read somewhere that a GS 1100 crank worked in the GS 1000 (1979). If so. what years and models. again thought the 4 valve cranks and rods were different than the 2 valve motors. thanks for any ideas

Thanks. Trying to keep options open on a rebuild of a 79 GS1000 motor this winter

Not sure, but would the GS1100 "G" (2 valve) crank be the one you read may fit the GS1000?? I've not worked on one, but figured the 1100 G was an overbored 1000 G. Just a thought.

May fit, but the stroke is longer on the 1100G vs the 1000G. I was informed of this because my 1000G with 1100G pistons is only 1054, not 1074 because of the slightly shorter stroke.

G crank won't fit either, bearings are larger on the G.
