If all else fails, sounds good. Probably cost less too!!!

Sure would be nice if just for once you could find a sight that tells you the size of the spline instead of everything else or tells you nothing.I guess that is the next question. Is the spline the same for the  transmission on the gs1000  and the Savage? This is like starting over. I know all this for Harleys and most British bikes, but not for Jap bikes. Thanks for looking.I haven't ate for 24 hours so I got to take a break.

i just got a wild hair and took my front pulley off. there is a spacer with the exact dimensions as mentioned earlier behind the pulley. possible no spacer needed. by the way it is not splined.

Here is my two bits.

Most all suzukis run a spacer/collar on the counter shaft.  Not sure why.  The oil seal runs on this collar.  It was common that the GS's and TS's would leak oil there when the counter shaft sprocket nut loosens up.  

What you need to do to determine if you even need a spacer is this.
1. Pull your front sprocket and measure from the face of the pulley closesest to your engine to the machined face of the pulley where the shaft goes through.  

2. Now pull your rear pulley and measure from the same face (tire side) to the mounting face.

3.  Subtract approximately 1/32-1/16" from measurement #2. (This is because the rear pully flange is about 1/32-1/16" wider than the front's.

4. Subract #1 fromt #3.  If the number is positive this is the thickness of the spacer you need in the front.  If you get a negative number then you would have to space out the back sprocket.

Personally from looking at them (with out having measuring them) I would guess you won't need any spacer.

What I did up above was look at the offset of each pulley with out calculating where each center line is.  There would be other measurements you could use but I thought this would be the easiest.

Lastly any spacer that is needed would not need to be splined.  There is no need for it.  Just pinch it down with the sprocket and nut.

Let me know if you have questions.  I can still rip mine apart if all else fails!

yep 10mm x 40mm although i am using a centimeter tape measure, and not a micrometer, so it's not a perfect measure ment, but i am within a mm.

using smokin's method the front is 19mm and the rear is 15-16mm ( i didn't take off the pulley and used the tape) so it appears that a 4-5mm spacer needs to be put behind the rear sprocket. again this is not perfect, but is close.

for those keeping track:

530 chain close to 110 links $40-50 (ebay)
sprocket front: gs550 (teeth of choice) $20
Sprocket rear: gs550 mag wheel (teeth of choice) $30
4-5mm spacer behind the rear sprocket. $5 (at the most)

total cost for chain conversion: $90-100

other than that looks to be close to bolt on.

check ebay for the chain you can buy an oring for 40-70 bucks easy, or an x ring chain for a few bucks more.

It's looking to me that when this part is fully seated that there will be 10mm sticking out, just like we need. Might have to shim back sprocket, I'll find out once I get sprockets tomorrow and get around to freeing up a jack. If the sprockets show up that is.Smokin_blue method will work and so will laser.tool I made.Thanks for the pics Greg     Hutch

Hey Hutch,

Here's the measure.  It is 9 mm from the seal retainer on the drive shaft....or add 1 mm from the seal.

Also, I have no idea what those notches are for.  All that I can see up in there is a bearing.  The spacer spins on the shaft.
