Has anybody?

Is there any info on the site or the available archives that details the modifications required to fit a GS1000 lump in an 1100 Slabby frame? Thanks

I remember seeing one done a good few years ago, will see if i have any pics.

l've seen it done, not sure if it was an 11 or 750 frame though...…(wtf were you drinking over the silly season?)

the frame rails top and bottom need cutting and extending as the air cooled lump is huge compared to the oil cooled one and simply won't go in the hole. Then you need to line the front downtubes so the exhausts don't foul and make the engine mounts. I don't remember if there is a width issue somewhere too. I know it's been done but it was a lot of work, I always wanted to do it as a replacement for the XR41 but lacked the blue glue skills...

Like putting an FJ in a GSX then but ally. I do have access to 2 chopped up Slabby frames so sourcing short lengths of the necessary extrusion won't be an issue. I've got other stuff to do first, like rebuild the engine and the shafty to fiddle with.

I've been more sober over the last couple of months than at any other point in the last 35 years... X

Here is a pretty informative thread: https://www.thegsresources.com/_forum/showthread.php?229202-GS-1000-engine-in-GSXR-1100-first-gen-frame

Never heard of anyone trying but seeing the 4" gap front to back when doing the reverse, its deffo gonna need stretching - then the GSX motor is also taller than even the 1100 oiler, that dimension is going to be a squeeze as well i'd imagine.......can't actually see the appeal as it weighs lots more!

Dan Hegarty gave me the motor just before he went off to Macau, he took an OSS  Slabby round the classic TT the year before. XR41 ish tribute bike.

Perfect Arttu, I reckon I could  do the frame neater than that

I'm struggling to see a 'first generation' frame there! More akin to a pre-prototype frame, factory built to go racing with a GS motor full of magnesium, one off, ltwt. castings - as a GS thou motor just will not fit into a std production Gen 1 GSXR frame as we all know! The XR41 frame looks more like a Harris with square tube...............could even be steel for all I know LOL!

He started the frame surgery after about 8 pages. Not very neat though. I will do the same dimension changes to top rails, bottom rails and  front rails but so as you'll not be able to tell. It'll be cool  I have a cut up frame to nick correct extrusion bits from. Head stock will be about 6mm higher than stock, will not overly effect rake with standard forks. The new CNC router at work will make the slugs...
