Okay.  I got one more silly question.

Are the splines on the countershaft the same as on the other chain drive Suzukis?

Yes yes and yes.  If you go back to the belt vs chain posting or chain vs belt what ever it was I posted quite a bit of detail there.  I am planning a chain swap this spring and here is what you want to look at/for.

First the GS 550 front sprockets will fit (as most of the gs/gt s will)  Now on the back I BELIEVE the GS550 rear's will also.  I have both a GS550 sitting in the garage and a savage.  I have measured wheels while on the bike but have not yet pulled my rear wheel.  \

Short of today's GSX-R's suzuki ran 2 front splines.  The savage is a 25mm major diameter with a 21.5 root with 13 splines.  This covers about 85% of all suzukis on the road from about 1977-1995.  As far as the size I think the 17 tooth front is right I would have to check I have the front pully and old gs sprocket laying on my garage floor right now.  

You can get any rear size you want for the GS series pretty much.  The 550's ran a 530 chain which is plenty big for this bike.  the GS750's on up were 630 chain which is a waste of weight.

As far as rear sprockets, again suzuki had approximately two to three rear hub designs.  This one appears to be common.

Go to JTsprockets.com and you can get all the technical info you want.  I have just not measured the rear pulley center hole and bolt circle off the bike but from working with it on the bike it looks good.

Dennis Kirk carries JT sprockets.

If for some reason you can't get what you need there go to sprocketspecialists.com and they have or will make anything you want...aluminum etc.

Lastly I am a firm believer in oring chains.  I used to use PJ chain lube on them but hate the sticky mess so now when I built my street fighter and put a gold side link chain on I went to chain wax.  I love the stuff.  Put it on a warm chain let it drie and wipe it off.  Looks great and nothing sticks to it and no goopy mess flying off.

hope this helps.

PS:  have not measured the offset of the two pulleys yet but that will tell us what kind of spacer you need in the front.

I plan my swap this spring and will know more then.  Also go back and find that listing I reverenced above for more details and discussion.

Good info here.

Chain wax is good too.  Since I don't have a belt guard, I don't really want all the goop flying off either.

Thanks.

Okay, buddy, maybe this will shed some light on the gearing.

I went to Ron Ayers and checked part numbers for the gears for different years.  For the sake of discussion, I'm gonna use the just the part numbers for the 5th Driven Gear...

Year - Model - Part number

1988 -  J   - None
1995 -  S  -  24351-24B12
1996 -  T  -  24351- 24B13
1998 - W  -  24351- 24B13
2000  - Y  -  24351- 24B13 (mine)
2004  - K4 - 24351- 24B13
2005  - K5 - 24351- 24B13

Of course, we know the 4 speed models don't matter, but I went back as far as their listing went.

This shows that some early 5 speed Savages had a different 5th Driven Gear in 1995.  This also shows that after 1996 the same gear was used my 2000 and in the first S40 in 2005 (model K5).

So, unless they changed it in 2006 just for you, then your's doesn't vibrate any more than mine

PS - I checked the primary and final drives too.  They are the same.  Hope this helps.

Thanks for the info Greg. Knowing my luck they did. Ijust know it screams at 80mph and it is not running weak on fuel or breathing. She is out of r's at 80mph.and revving like a screaming banshee.I can drive through town in 5th gear@25mph, get to the city limit and just crank it on with out down shifting.I went to Dennis Kirk and they don't have the right sprockets either. I found the 17/45 combo at the link tbalam put up on the first page of this thread, $50 for both sprockets.

I was perusing the german site and in their tech section found microfish of parts, 'MotofichesJS1NP41B.pdf'  I copied the gears from the transmission page here.

As you can see, there's several part numbers for each gear.  I think the letters on the right are year codes.

Year codes from a VIN decoder:

1995 =      S
1996 =      T
1997 =      V
1998 =      W
1999 =      X
2000 =      Y
2001 =      1
2002 =      2
2003 =      3
2004 =      4
2005 =      5
2006 =      6
2007 =      7
