The front brake system is NOT designed to push 3 pots.. It is designed to shift two per side..
You try and use all three pots and the lever will feel like wood and the stopping power will be greatly reduced
With all due respect, before offering an opinion at least check the basics good sir
Yes, I have got an 800 vifer swing arm, upside down forks ( did not like the SP 1 things so went fro Kwak )
Arse end is a reworked Ducati 916 on home made sub frame
Re swing arm.
It is not quite as straight forward as it looks.
The shock mounting point is off set on the swing arm.
I made up an off set dog bone and shifted the top mount where it goes through the frame by about 25mm
