Hi Dibble1
I must congratulate you on the fine choice of a B1. 🙂
The chain guard is I feel an important part of your bike not just safety wise, but visual wise as well. Its a personal preference thing on the looks of it.
You will be able to get something to fit.
Its just going to be a case of looking at other bikes you see, and seeing if you think it can be adapted?
Ill keep me eye out to. 😉
The Mounting points for the chain guard are quite close together on the B1, I think something from a Z1 or a Z650 may be close! 😉
