Oop's, forgot to thank Katman for supplying the rear sprocket,chain, spacer,advice and shop tour. Buy your conversion kit from him, he needs to fund his turbo project. Pete.

I desparately need to get a chain and sprocket kit for my '78 GS1000C. I need to have the bike ready by friday june 11th.
I need to know what tooth count on a 530 will match the specs of a stock 630 chain.
630 sprocket tooth count 15 and 42 correct?

Whats it gonna take to match?....18 tooth front with a 47 to 50(ish) rear?

**EDIT** OK, I figured it out... "IF" the stock 630 sprockets are 15 and 42, that gives you a final ratio of 2.8:1
So to go to a 530 chain and retain the same final drive ratio it would take a 17 tooth front and a 48 tooth rear which gives me a 2.82:1........or, a 18 tooth and 51 tooth combo gives me a 2.83:1 final ratio.

I just need to find a place near Edmonton that sells the kits...anyone have any ideas?
