530 17/38 conversion

Just done a 530 conversion 17/38 its a dog, has no take off. Should I have choosen a different combo.

what bike do you have?

77 KZ1000

Do you have a LTD with the 16" or a standard 1000 with the 18"?

Later, Doug

a you looking for better accel or top end? what other mods do you have?

How did it run before?

Am thinking most earlier large Kaw fours have stock 15 tooth counter-shaft sprockets;
some with 35 tooth final drive sprocket on USA models;
and 33 tooth final drive sprocket on UK models.

To convert 630 sprocket to 530 sprocket, multiply number of 630 teeth by 6/5 to derive 530 teeth equivalency.
For example, a 15 tooth 650 = 18 tooth 530
The math: 15 X 6/5 = 18
33 tooth 650 = 39.6 tooth 530 (or say 40 tooth 530)
35 tooth 650 = 42 tooth 530

To convert 530 sprocket to 630 sprocket, multiply number of 530 teeth by 5/6 to derive 630 teeth equivalency.
For example, a 40 tooth 530 = 33.33 tooth 630 (or say 33 tooth 650)
40 x 5/6 = 33.33
An 18 tooth 530 = 15 tooth 630
18 x 5/6 = 15


Chain length:
630 pitch = 3/4" 86 link 630 86 x .75 = 64.5" 86 x 3/4 = 64.5"
530 pitch = 5/8" 104 link 530 104 x .625 = 65 104 x 5/8 = 65"
Quick estimate:
Multiply number of 630 links by 1.2 for equivalent approximate number of 530 links
Example -- what length 530 needed to replace 650 with 86 links?
The math: 86 x 1.2 = 103.2
103 link 530 is about the same length as an 86 link 630.
The math: 92 x 1.2 = 110.4 (or say 110)
110 link 530 is about the same as a 92 link 630.

Good Fortune!

Maybe try dropping front sprocket to a 16 so you can keep same chain

I am riding a GPz1100 powered bike and I also did the 530 chain conversion. I too did all the math and thought I had it right but guess what I didn't I started with 16/38 then 16/42 then 17/42 and I ended up with 17/46. That combo for me is really a good compromise of low end, cruise and high end.

From what I remember of the gpz's the trans is geared a little differant from kz isnt?

What were teeth counts on the stock 630 sprockets?

Good Fortune!

Don't have any idea what the teeth count was on the 630 sprockets. I took the engine and transplanted into a GPz750 frame. Never rode the stock GPz1100. I just kept putting on front and rear sprockets until I got to where I liked it.
