    630 to 530 chain and sprocket conversion.

    HI

    Currently running 630 chain and sprockets. Chain has tight spots in it really bad so time for replacement. I want to convert over to a 530 chain and sprockets.

    Have looked at previous posts for info but just need to ask some questions. I believe i need 18T and 50T 530 sprockets to match the original 630 setup in regards to gearing. If so why do some conversion kits for gsx 1100's have 530 sprockets matching the 630 sprocket 15T and 42T.

    Am looking at Sunstar 530 sprockets, are they any good? Want to get a X ring 530 chain how many links should i get to play it safe? Finally do i need a spacer for the front sprocket, if so where do i get them from?

    Any help appreciated

    Thanks

    Contact Z1 Enterprizes, they have all the info (and parts if you choose to order from them) you need for the conversion.

      530 Conversion

      ^^Second that notion. I bought my conversion kit from Rob at Z1 (as well as my V&H/4-1) and was ready to install but sadly, the front sprocket lug would not cooperate.

      Thank goodness for friends like Bill. He gave me his 630 (which was in better shape) until I'm able to have that lug removed with an impact gun.

      Good luck!

      my opinion shouldn't be taken as gospel or in any way that would lead you to believe otherwise (30Sep2021)

        A 17/48 in the 530 set up will put the gearing back to stock gearing. The 17 tooth 530 sprocket is the same diameter as the 15 tooth 630 sprocket. the sprockets in those sizes can be ordered for a 1st or 2nd Generations Bandit 1200 will fit both your counter shaft and rear sprocket on both your GS1100's and GS1150's or your Euro GSX1100's I can't remember the chain length exactly but I think it was around 120 links.
        Hope this helps you.

          As written by Rob Darby from Z1 for my 1983 GS1100E.

          GS1100E - The following 530 conversion is a 2.78 ratio:

          http://www.z1enterprises.com/ItemDet...=BAJTC530X1RSL – purchase 2. One as a spare for under the seat or tool box.

            The 17/48 is a 2.823 gear ratio the 18/50 is a 2.777 gear ratio the stock gearing is 2.800 the reason I like to use the 17 tooth 530 counter shaft is because it is the same diameter as the 15 tooth 630 countershaft and the GS is already geared to tall for the bike from the factory.

              Order at least two extra master links. Never hurts.

                Based on your reasoning Stretracer I will probably run the 17/48 combo myself. I like the idea of more take off vs top end. Especially when my bikes rarely ever make it out of town.

                  If I may ask, what are the advantages of going from a 630 to 530?

                    Less weight. Specifically, less unsprung mass (weight on the ground side of the suspension), less rotating mass in the drive train makes anything related to power transmission to the ground easier and smoother. And... it looks cooler, not as antiquated.

                      Not being picky but it's stetracer. I do a bit of drag racing and it stands for the two classes I race in street and pro et hence the st-et-racer not stret racer. I guess I should have put a couple of dashes in there. If you really like some pep use 16/48 which is 3.00 gearing.

                        With the 530 being smaller in diameter is there any wear / durability issues?

                          I stand corrected on your name. Lol. And thanks for the suggestions on the 3.0 gearing.

                            Most say the new 530s are stronger than the 630s. The BMW and other (nearly) 200 hp bikes all come with 530 chains.

                              Metallurgy of newer chains are much MUCH better, plus there was a bit of CYA back in the day. Not from BS lawsuits, but because the Japanese wanted to make their bikes as bullet proof and reliable as they could, so they often overbuilt them.
