GS1000 engine in GS1100 frame, easily doable?

[jknappsax]

I have a spare GS 1000 engine with 14k on it, and I'm wondering how involved it is to transplant the engine into a GS 1100 frame. I have a GSXR 1100 front end, wheels, and brakes, along with a GS 1100 swingam, (and a spare GS 1000 harness) which I've been planning to install on my GS 1000. But I have a line on a GS 1100 frame, and I'm thinking of building a bike. How much fabrication of motor mount plates, etc. would this install take? Thanks in advance for any advice you might have.

I did the other way around 1100 in a 1000 frame

get the rear bolted up and mark the front frame tubes.. on a scale of 1~10 it is a 4

Sorry, I've got to ask. What are we marking on the front frame tubes for??? Only problem I had, puting GS1100 "E" eng. into a GS1000 "C" &"S", was to relocate the motormount under the gearshift.

I put a 1000 motor into an 1100 frame. '83 I think. Everything matched up except for the left front motor mount. I had to cut it and weld a piece in the middle to extend it a bit to reach the motor.

I had no problems with the front mounts, I had to mix & match the mounts form both the 1100 & 1000. Used some from both. Fronts worked fine, but none of them would match up with the mount under the shift lever. I chose to move the mounting point on the frame foreward appx. 1". May have been easier to fabricate a mounting plate that would fit. Neither should be a big problen.

I appreciate the advice and your experiences with this kind of swap.
