BrandEn, I live in the Madrona neighborhood. How about you? Checked out your pics of TAO, noticed the PO did some mods... namely rear disc brake. How's that feel compared to the stock drum? Does it make a big difference in the rain?
Cool, I am in Des Moines just south of SeaTac...
The 75-76 CB750F's (F0-F1) came with spoked wheels, rear disc brakes and a single disc front.
The 77-78 CB750F's (F2-F3) came with Comstar mag wheels, rear disc brakes and dual front discs. So my bike came stock with the rear disc.
All the SOHC CB750K models use a drum rear brake.
I converted TAO to spoked wheels using a 75F rear hub and a 75 GL1000 front end. Mainly just to ditch the Comstar wheels. The rear definitely is better than a drum brake, but as far as riding in the wet it is a bit better although I don't ride this bike in the rain if it can be avoided. Hope this helps!
