"Steel 520 x 17 Tooth Front Sprocket Lighter Weight and more chain clearance for your 650(Note: Must use with 520 chain and rear sprocket) *** this sprocket does not have a thicker center and needs shims to modify"

Mikes and 650 Central are out of stock and I talked with MM at 650 Central today and he said he wasn't planning on ordering any more.

Has anyone ever compared XS front sprockets to old Honda CB sprockets?
 
Sprocket Specialists has them that have the wide mounting center flange so no spacer is needed. I`m running a 16T but they have all sizes.
 
Heard back from Sprocket Specialist:

"Hi Bill, thanks for the order via our website. We are currently back ordered on the 17 tooth without an ETA. I will refund you the cost of the 17 and ship the 16 today. Sorry we are backordered, check with us in 6-8 weeks on the 17 tooth status."

Glad I ordered the 16.
 
That is correct. If you try t to use a O-ring chain it will hit on the engine case. I use a non O-ring and mount the sprocket (16T) to the inside. The rear 520 sprocket does not have the thick flange.
 
Note be sure to offset sprocket to outside or dont use o.ring chain see wjl thread for why.

As I ordered an O-ring chain will I need to do anything to the rear sprocket other than change to the 520 pitch sprocket or will it give me that much misalignment and still work okay?
 
If you can find a sprocket that's 530 base and 520 at the teeth you can run it offset to the outside then they will line up. 1/8" diff in width 520-530
 
I ran into this while browsing the web for your sprocket, a useful piece of kit for the wide tire guys.
