Best year frame to put a GS 1000 engine in?

[jknappsax]

I have a spare 14k GS 1000 motor, and am thinking of building another bike, with GSXR 1100 wheels, forks, etc. Is there a particular year frame that is especially stiff, or whatever thoughts you might have on the subject. Thanks.

Pretty much all the same for a bolt in.

I look at some of the square section frames, like the 1150, and think that they must be stiffer than a 1978-1979 GS 1000 frame. I've seen good threads here and OSS on frame bracing, but I figured, start out with the most rigid frame I can get, as that's got to be a step in the right direction. I have a line on a 1979 GS 750 frame, which I know doesn't have the cross-brace between the downtubes like the GS 1000 frame, and another on a 1979 GS 1000 frame, but I figured I elicit opinions on what might be best to start with. Thanks for any input.

After checking the fiche at Alpha-Sports, it looks like all the frames up to 1985 are pretty similar, so I guess sticking with a 1979 GS 1000 frame is probably the way to go.

I agree with you.

The motor will bolt right in and you can brace it up while you do the mods
