Need new chain and sprockets

I have a 76 Honda (K6) CB750 and I want to replace the chain and sprockets.

I have no idea when the chain was last replaced and I want to change the sprocket combination anyway.

The stock setup is an 18:48, 104 link, 530 Chain. I want to replace it with a 18:42 setup and the same 530 style chain so I can drop the RPM's and eliminate some of the "buzz" at highway speeds.

Is there somewhere in Houston that I can get these items? I'd like to buy locally; somewhere that is open on Saturday would be best.

You try Motorcycles Unlimited? I use them as well as most of the people on here. If they don't have it in stock, they can usually get it in a day or so.

Give them a call....

By changing the rear sprocket you may need to pull some links out of the chain. The circumference of the front sprocket isn't effected very much when raising/lowering teeth. See if you can go up on in the front instead.

You'll gain some top end speed/rpm but the overall power 'feel' will be reduced due to down-torquing the output inthe final drive assembly.

Thanks a lot. I'll definitely see what they have.

Yeah, I know I'll lose some off-the-line torque, but I think I can live with it. The buzz at 70mph on a 32 yr old bike is just too much. I think dropping from the stock 18:48 to an 18:42 will drop me about 500 RPM's at 70. I'll confirm with the above mentioned Vendor though. Thanks.
