Replace GL1100 fork with fork from newer bike?

I'm starting to plan my effort to make a 1st rate touring bike that doesn't weigh 900 lbs. plus.

Plan is to take a GL1100, do suspension upgrades and aftermarket electronics and luggage.

1st step is suspension upgrade. Seems like the easiest option would (might) be to buy a complete front fork ass'y from a newer bike. More of these around than you might think due to racers and track day fanatics upgrading their suspensions.

could easily be cheaper than a simple upgrade of internals and I'd be able to upgrade the brakes at the same time.

So ... can anyone out there that knows a lot more than I do suggest how I might identify likely candidates for donor bikes? My fab skills are relatively modest so I'm not planning any frame cutting or welding.

bump. I'm still hoping for some advice.
what year 1100 are you going to up date ?
You could maybe go from a 37mm (84-87) to a 41mm tube by swapping the tripple clamps from a GL1500 (88-91) ... (upper and lower bearings are the same; I'm not sure about the spacing though)

I seem to remember toying with putting the inverted forks from the '02 VTX1800C on an early 1500 at one point - stem bearings may be the same... but I can't speak to the spacing (length of the head tube)
I like your thinking . Sorry I dont have any info to offer .
thx for replies. I haven't bought the GL1100 yet as I think I have considerable research to do.

I'm assuming an 1100 due to alternator issues on the 1200's. should be an interesting project. I'm guessing I can come in somewhere near 200 lbs below a GL1500.
A few guys at NGW have out Gixxer front ends on using bearings from Allballs and a little grinding. One, at least, has used triple trees from a gl1200 and out a front end on from a CBR.
