630 to 530 conversion HELP

I'm in the process of doing the chain an sprocket conversion from 630 to 530 on a 1978 gs1000e. I ordered the parts from z1 enterprises and they set me up with all I needed, I thought. Perhaps I have all I need, but I'm confused about the amount of space on the outside of the front sprocket.

The original front sprocket has some covers on both sides which take up the excess space on the shaft. But, the new sprocket's treaded holes don't line up with the covers. It sounded like, when I ordered, and I've read threads that I ordered all I needed. I have a few pictures below that shows what the old front sprocket looks like. Another of the new sprocket and two spacers that came with the sprocket, and the other picture is of the new sprocket on the shaft showing the amount of extra space. I'm sure I'm doing something wrong, or don't have a full understanding of how to install.

The old and new.

Thanks scudder
 
Usually when converting you put a 3mm spacer on the outside of the front sprocket to take up the additional space on the splines.. :)
 
Yup. I told them. They included 2 spacers, but they were a total of maybe 2mm. The nut won't tighted down with the smaller spacers. It's still a little loose. 6mm looks to be what I need. Thanks for the link and help.

I got one of these off Katman

Spacer built in.Just need the rest:-$
 
No it's one with a spacer built in.Could be an offset to but for me it's a spacer.
 
When I did my 530 chain I used the 6mm spacer.
I got everything from Z1

http://www.z1enterprises.com/Front-Sprocket-Spacer-Washer--6mm-1886.aspx
6mm Sprocket Spacer with 25mm center - can be used with 518 series front sprockets on Suzuki GS models. Can be also used on other bikes to off-set the front sprocket. Please insure enough of the front sprocket is on the output shaft spline, and there is clearance for the chain to clear engine cases and frame tubes.

This washer goes on the OUTSIDE of the sprocket! Not between the case and the sprocket. ~~~~~~~~~ The early GS series bikes came equipped with a countershaft sprocket that was sandwiched in rubber for dampening purposes. This spacer takes the place of that rubber sandwich. To the best of our knowledge, the following bikes came with the rubberized sprocket: GSX750LT, LX, T, ET, EX, EZ, SZ 1979-82, GS1000 ALL 79-82, GSX1000 ALL 82-84, GS1100 E-L, ES 80-83, GS1100 E, ES 84-86, GSX1100 SZ, SD Katana 81-85, GSX1100 EZ, ESD 80-85, GSX1100 EF, EG 85-88

Oddly enough, I am looking at the EXACT same dilemma in my garage right now with the Z1 conversion replacement for my 750T. Did you figure it out? I am thinking of heading to Lowes and looking in the washer drawer..
