Thanks all. The forks / bars are the original BMW setup (at least I assume it is, it all fitted within the fairings ok before disassembly). I think I will measure the max deflection with each option and see what the difference is. I’m leaning toward the last one too, even if it will mean more welding.
For some reason the tanks always seem to leak at the lowest point each side, I guess as water gets in and sits there. The original tank cap leaked and dripped water into the tank.
It’s a 1983 bike and the loom is a mess, I assume where it’s been repaired or altered in the past so I might need to make a new one. There are various after market gizmos for reducing the amount of wiring required though. It’s 50/50 weather I get this finished before I shuffle off this mortal coil or the earth is taken over by aliens but it’s fun to do.
