Will humans, one day, be actually required a virtual passport to routinely enter the world web or to acquire one day visas for visits? With our physical travels being more & more restricted by "agencies" does it not follow that our keepers are even more interested in regulating our intellectual abilities to assemble and disseminate? I'd suggest more than just the groundwork has already been laid & we are closer to "then" than to "when".
I ordered a 32 tooth sprocket to replace the 27 tooth in order to fit the 3 hole hub adapter on the drive side, as the three hole pattern required to bolt to the sprocket was into the teeth, close but to close. If you recall I'm using two 3 hole hub adapters on the rear hub mounted back to back. One side holds the rear disk rotor and adapter in place and the other will be used for securing the sprocket assembly in concert with the hubs 6 hole disk rotor pattern. The 6 bolt pattern uses 5 mm x 12 mm grade 11 fasteners, which though fine for smaller motors, I'll not trust for 20 hp +. The two hub adapters of course can't be fitted back to back, the hub is too narrow to allow assembly, but by removing the sprocket adapters bolt stands on the sprocket side adapter they just fit. I will need to drill and tap the body of the hub adapter to accept the three 3/8" NC 16 bolts. Three all thread connectors will provide the correct standoff between sprocket and adapter. Then the two back to back hub adapters will be bolted together as a solid unit.
This design eliminates the possibility of the hub adapters ever spinning into the spokes under power or breaking. I also machined a full width aluminum insert for the hub body which is press fitted and not only strengthens the hub during operation but also prevents any distortion of the hub due to torque while mounting the twin hub adapters.
This rear will be solid and still look more bicycle than motorcycle. Small, clean and simple appearance are among my design goals for every bike I build. Rick C.
