no one seems to have any further contact info for him. Ideas as to how he might have done it?

Me and onederer both must be idiots because we came to the same initial conclusion IE something must be done to space the sprocket outward. It turns out thats not the case. For the rear wheel you need axle spacers of 42mm long x 17mm ID x 38mm OD. This will put a gs450 wheel just about dead center AND align the front and rear sprockets. What needs to be done both front and back is some jerry rigging with the brakes. Rear brakes - I used the gs450 assembly which uses a torque bar to keep it from spinning with the wheel as you brake. I just fashioned my own bar from piping and mounted it using the lower rear shock bolt. You'll need 14mm and 10mm drill bits for this and the top of the copper torque bar has to be bent in something of a Z shape to clear the swingarm. You'll also need a longer shock bolt . 1/2" x 3" Grade 8 with suitable nut and washers. Couldnt find a 14mm anywhere. 9/16 is too big and 1/2 is too small. I was lucky enough to have a bunch of extra bushings from my set of progressives. One of them fit right over the 1/2 bolt and snuggly fit in place in the 14mm shock mount hole. If you arent already replacing your stock shocks with progressives you'll have to have some sort of bushing made/purchased to take up the extra space with the stock shock mount hole.  Front wheel - My gs450 front wheel came with its own axle spacers and between mixing up the gs and savage spacers im not sure exactly what i ended up with. I chose to have from spacers made aswell but i thought the front axle was also 17mm OD. Its not. The correct dimsenions for front axle spacers is 33mm long x 15mm ID x 40 (roughly)mm OD. This will put your front wheel center. As stated previously you'll have to have the brake rotor machined down to a 10.25" OD and space the brake caliper inward 1/4". To space the caliper I just got some 10mm ID washers from home depot. 3 of them end up at exactly 1/4". You'll also need longer bolts for the caliper. 2 1/2" i believe. Measure the stock bolts and ad an extra 1/4". I will provide pictures of what I've done but Im not promising they'll be up soon. After all is said and done it's not as difficult as I made it seem...or as difficult as i made it even. For anyone else that decides to try this rest assured it does work. It works well. Just dont get frustrated. And be very patient getting the bead to seat on the wheels. Use LOTS of soapy water and a high pressure air pump and it shouldnt be too strenuous.

Dang BP.  You go all out when you mod!

Harley mags do look good but...Ineclipse intends to swap out kawi 454 wheels. He'd be the first but I've seen the rear wheel and its about the same size as the savage. Pretty well offset pulley...like the savage. Im willing to bet his conversion is going to be no more difficult than mine and maybe significanty easier. Its already been determined that the belts will swap.

What years were the front and rear wheels and disc?   Aside from the spacers did you need anything else besides those 3 main things?   Different hubs,  etc....?

Well I guess uigiroux has no issues with the searching the site like others  

I was looking up some info on the GZ250 because the hub looked like it's drilled for the '80's GS style front disk.  
And that led me to the TU250 cause it shares the same hub.
The TU250 has a 18" rim while the GZ250 has a 16" rim.
The only disc catalog that I can find with dimensions is from Gold Fren but it doesn't list either.
I think it was bike specs that listed the front disc as being 275mm vs ours witch is 260mm.
I've taken the GS450 disc and cut it down to 260mm for the savage using GS wheels.

If anybody has any dimension data on the disc's I'd appreciate it.
