    Chain Conversion (Again)

    Yes, I did do the search, but couldn't find all the info. I'm doing the 530 conversion thing to my '82 GS1100EZ and am changing the sprockets to 17 from 15 on the front, and 48 from 42 on the rear. That will change the gear ratio from 2.8 to 2.82. Big whoop.

    What I need to know is, are the sprockets the same on the '83 (ED) and the '82 (EZ)? I assume they are. The numbers I have are JTF513-17 for the front, JTR816-48 for the rear, and spacer JTF518B. Also, I need to know chain length. I have seen a few people have done this conversion, but not a lot have said how long the chain has been. If worse comes to worse I'll buy a 120L chain to be safe, but if I can save a few buck with a 110L chain, I'll go with that.

    Thanks.

    Re: Chain Conversion (Again)

    How many links were there in your stock 630 chain?

      Just did this conversion on my 83 GS1100E (yesterday) and I used the 120 link DID xring chain, ended up cutting approx 5 links off to fit my bike. so figure 115-116 links

        Just crawled around on the floor and counted them. 96 links.

          I just did the conversion on my calculator. For those sprockets, you will need 114 links of #530 chain.

          I am assuming your rear axle was not all the way forward with 96 links of #630 chain. If it was, add one link of #530 and use 115 links.

            chain

            Dude just buy the 120 chain cause if you mess up they wont take the chain back, and a few extra links wont kill your wallet

              how do you break the chain links anyway? hammer and a chainsaw? (WAKKA WAKKA!)

                Just grind it off at the outer link, or use a chain breaker tool.

                    For Canadians doing the conversion. If you order through Motovan, they are retarded and have their own numbering system with no cross-reference. A JTR816-48 is Motovan #324-9743, and a JTF513-17 is a 324-9262. 115 links are required for a '82 GS1100EZ. For a spacer I took the stock sprocket apart and used the outer piece after I ground it down. I found the diameter was too big as the chain was riding on it. 8)

                      Yep - that's the way to do it. Don't take a hammer to it. 8O I agree about getting the longer chain.

                        I just noticed that the previous owner put a 42 tooth rear sprocket on when he did the 530 conversion. Could this be why it takes forever to break 100? I'm gonna see what he put on the front tonight. He said he kept the original gearing, I thought he meant the same gear ratio, but it seems he meant the exact same number of gear teeth. If it has a 15/42 in a 530, how would the bike react? I'm guessing that he put a 17 on the front, because a 15 tooth 530 sprocket would be garbage real quick.

                          If the former owner used the stock sprocket sizes, (ie number of teeth), the gear ratio would remain the same. The chain size makes no difference. The gear ratio is still 2.8. I went with the bigger sprocket on the front because, like you said, a 15 tooth would be garbage in no time. To compensate for the larger sprocket on the front, I had to go with a larger sprocket on the rear to keep the gear ratio the same. 8)

                            Now, I've gotta ask - why would a 15 tooth 530 sprocket wear any faster than a 15 tooth 630 sprocket? The number of teeth are the same, the load sharing is the same and the chain is bent around the same radius, relative to it's pitch. So what makes you think it will be worse?

                              They say it's becasue the actual sprocket is smaller in size, in other words, the same torque applied to less meat. I don't know if I agree or not, but I'll let you know this summer because it looks like my ft cog is 15T. So the PO was correct, he kept the stock gearing.
