Hello All,
I have an '88 model GR650 (Tempter) and am wanting to make it more suitable for highway speeds.
It has no trouble doing those speeds with the stock sprockets but when doing so the revs are fairly high and right at the point where engine vibration becomes annoying.
Stock sizes are 38 rear, 15 front.
I've been unable to source a smaller rear, I believe 36 was used when these bikes were popular but I can't find one anywhere.
I did manage to find a 16 tooth front that is currently on it and does help somewhat with lowering the revs at highway speeds.
However it's a 520 that's made for a GN400, whereas the rear sprocket and chain are 530.
I'm about to replace the chain with an x-ring 530, currently an o-ring 530.
Any issues with doing that or running a 520 front with a 530 chain and rear that anyone knows about?
Had no issues so far for about 1500 km's.
Thanks
EDIT: better include a pic
EDIT2: does anyone know of a smaller rear sprocket from a different bike that might fit?
