GS1000 streetfighter idea w/ picture

Just dawned on me that I need to measure and check front/rear wheel alignment before mucking with the sprocket carrier and wheel spacers since they're all part of an interconnected system in terms of dimensions. Once I get the front and rear wheel aligned and in the same plane, the spacer dimensions and amount the sprocket carrier needs to be milled should fall into place. The chain's gotta line up and the bike can't pull to one direction or the other.

Some good info on motorcycle wheel alignment here: http://www.google.com/search?hl=en&q...=Google+Search

Very curious to see if your 5.5" rim makes lining up the chain any easier for you since we now know the sprocket carriers between the 600/750/1000 are the same dimensions.

phew - I didn't think I was going to have to muck with modding the carrier and you had me worried. :shock:

Hopefully I'll get out to the garage on Friday night after the kids are in bed. (Canucks play on Thursday so of course that night's a write-off!!).

6", you may have an easier time with the 5.5". I may switch to the 5.5" if trying to make the 6" winds up being too much of a PITA.

Are you running a 6" wheel or a 5.5??

Good luck with it, I'll be watching..

You're a lifesaver - thanks for taking the time to measure them up. All the dimensions you posted are the same between the Gixxer 600 and 1000. Sooo, next comes the adventures in sprocket carrier milling.

Crap - got the pictures reversed, but the measurements are correct.

And I guess I didn't measure the 6mm to the mounting flange properly - it should be 7mm same as yours...

And here's the measurement of the posts themselves - 27mm.

Hope this helps..!

Here's the measurement from the bottom of the posts to the sprocket mounting flange - 34mm

This shows the format - probably the same, but just in case..

Great, thanks for measuring. The Gixxer 1000 version is 7 mm. How tall are the blocks on the back?

Ok, this shows the measurement from the edge of the wheel to the sprocket mounting flange - 6mm

being too lazy to walk out to the garage and look at mine to confirm, from the pic I'm guessing it might work as long as you can work out the bearing spacers etc. I also seem to recall reading that a carrier from a different wheel (stock?) fit and was a lower profile - maybe Katman's ICBM thread... worth a look.

I knew the good chain clearance was too good to be true. I jacked up the rear wheel off the ground a few inches with the white stand shown in my signature pic to simulate shock travel with the chain mounted on the front and rear sprockets. Then I checked for chain clearance by rotating the rear wheel - clunk clunk clunk as the links hit the frame. <bangs head>

With the rear sprocket moved inward, we should be good.

Did a search and the magic 8 ball is pointing toward machining the sprocket carrier.

Tentative plan - cut 6 mm off the blocks on the rear of the sprocket carrier, then machine some spacers. The bearing spacer would be shortened by 6 mm. The second spacer would be a copy of the stock one between the swingarm and wheel, but 6 mm longer. I gotta remeasure a few times and make sure 6 mm is the right number.

If anyone knows of a sprocket carrier from another bike that's shorter than the GSXR 1000 sprocket carrier, and will fit in the GSXR 1000 cush drive, I'm all ears. :-D I tried the sprocket carrier from a 2003 Katana 600 that was laying around the garage, but surprisingly it was taller than the GSXR 1000 carrier.

Johnnay- If it's not too much trouble, could you measure the width of your GSXR 600 sprocket carrier?

The other thing I need to check for is wheel run - making sure the front and rear tire are lined up.

Very tentative idea, but here it is:

Cut about 1/4" (~6 mm) of height off each of the 5 "blocks" on the rear of the sprocket carrier. With the 520 chain, there's plenty of room to play with.
