Sprocket question for xs650 running a cb750 18 rear.

[darynar1016]

Well the title says most of it. I was curious as to what my options were for running a 33t sprocket on a cb750 18 rear drum wheel.
I have a 17t front sprocket and looking for a 33 for my rear wheel but can't find anything that seems like it'll work.
I'm pretty sure its the cb750 k7 wheel, it has the 4 lugs for sprocket mounting.
Any help would be appreciated.
Thanks.

You might have to get one made. Sprocket Specialities I think makes custom sprockets.
