My BMW R75/5 project.
Luckily, the motor was already done. R100 top end, BMW hot cam, lightened flywheel, Mikuni's, Dyna Ignition, short ratio rear end.
I've since converted it to a long wheel base as the short wheel base config was just too twitchy.
I've added sandblasted and clear coated Lester wheels, a braced swingarm.
Still trying to decide what class in AHRMA to commit to.
It runs really well and sounds even better.
I've done a trackday at B/W couple years ago and that's where I learned that the short wheel base was crazy.
