finally replacing the chain and sprockets

[tc862011]

i have been putting off replacing the chain and sprockets, they arnt horrible but i dont want to wait until they are. i have changed them since i got the bike and i have had it for about a year and a half. its the 1978 suzuki gs550.i am not sure if it has already been converted to 530 but that is the setup that i am going with just want to know what size sprockets i should go to, i live in the city so i do some city riding but i also like to do stretched out riding in the country areas that dont have many stops signs and have nice long and twisty roads. thank you

I just did my GS 750T over the weekend. It was pretty painless only the riveting of the master link was a little cumbersome. I was told by fellow GS'ers to call Z1 and tell the techs what you have and they will look up specs and let you know exactly what you need- I went from 15/41 teeth to 18/49 with 115 link 530- runs really smooth now as well.
Have fun with it!

thank you for the help. it looks like a pretty simple job. i will have to call them. i was looking at a simple ordinary 530 chain with the sunstar front and rear sprockets.

Your Welcome! One note my front sprocket had plate with three screws in it-
The new sprocket came with a 6mm spacer and I was told that you don't need the plate from the old one on your new one, some type of balancer- just the 6mm spacer, the lock tab and nut.
I chose to rivet instead of the locking clip master link- just didn't look sturdy to me.

They are fine actually. I have a Harley friend/mechanic that makes me smear black automotive weatherstripping adhesive on the link clip. It takes a real effort to get that stuff off, so the clip is never going to fall off. It is not affected even slightly by anything you put on the chain.

I wouldn't think too much about ratio sizes, it''ll drive you crazy, lol.
Just do a straight conversion, unless you're unhappy with the factory ratios.
