    Sunstar 530 conversion kits

    Anyone used one? Are the gear ratios listed the proper ones? Thinking about these guys when the income taxes come back..the chain and sprockets on my 77 750 are toast.

    Also was wondering if the ( stock ) chain and sprockets from a 78 1000C would interchange with the 77 750. I have a full set of good front and rear sprockets and a great chain, so was pondering using them on the bike as well.

    I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.

      Hmmm...I used the Z1 set up. My stock sprockets were 15/41 with a ratio of 2.733333 and with the conversion 18/49 with a ratio of 2.72222
      They are saying with sprockets of 16/45 with a ratio of 2.8125. That is a bit off from what Z1 recommended for my bike to stay as close to the stock ratio.

      So your bike is: Stock 15/41 2.73333 same as mine and Sunstars conversion 16/45 is a 2.8125. Don't know what that would translate to engine RPM in high gear. couple hundred faster?

          But what about me directly swapping the good ones on the 78 1000C ovet to the 77 750? If i can do that i will be able to save the cash and still be able to ride the 750...see what I am asking as far as can these interchange???

                  They will fit , weather the ratio is the same not sure.
                  I just looked in the PU catalog in it list's the ;
                  750- 15- -41 630

                  1000--15 --42 ----630, both 96 links
                  so yes just a little lower geared

                              The 78 1000C sprocket and chain swap was a resounding success. Bike is so much quieter with smooth running rollers on her.

                                  I'm currently going over the conversion parts and Sunstar does pop up often. They seem to the current leader when it comes to pricing. Is their quality that much more than the other conversions? I've got an email out to Jeff at Z1 to see where he is in this. I'll take quality over pricing, but where is the point of diminishing returns?

                                      I talked to Jap Bike Randy and he says Sunstars are EXCELLENT sprockets and chains.
