I know this is a predominately a 919 corner of this forum but I could use some help in the Old Codger section of naked bikes. Along with my 919 i have a Honda nt650 hawk. Its a great bike. Putting some new tires on it and cannot find a eccentric bearing carrier wrench to loosen the chain anywhere. Any ideas(that don't involve explosives)?
17mm socket and a 6" extension to loosen the clamp. but that's not what you're asking about, is it?
Once the clamp is loose stick the tip of a flat bladed screwdriver in one of the adjuster slots and rotate the rear wheel counterclockwise until one of the sprocket nuts contacts the blade. Continuing to rotate the wheel will take the eccentric adjuster with it, loosening the chain. At first it it takes a couple of tries to keep the screwdriver pushed in and rotating with the wheel, but by the second or third try it becomes second nature. It is by far the quickest chain adjustment possible on any motorcycle -- less than a minute. Just remember to run the chain a bit on the loose side to protect the frame guard below the lower run of the chain.
Great bike, the Hawk. Still have my Blue '88 with over 140,000 miles on it.
If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.
