See, that's cool as all hell!
The next project is the TR7V Tiger, a single carb version of your bike. I do know there were labour problems at the factory and the T140 'gremlins' all disappeared when the issues were resolved. Maybe what happened to yours?
To be honest, the T120 was the biggest thing I'd ever done and I was way out of my depth. I had to immerse myself in Triumph history to find out why nothing worked right and why nothing went easy. At least half of it wasn't my fault
. For a rookie build - I wouldn't recommend a Triumph from that era.. but you do learn a thing or two..
EDIT: if I ever meet that Lucas electric guy I will fight him.
