Having completed the recommissioning, took the EXUP for a quick ride out.
Bedded in the new brakes and new tyres too, so just an easy ride. The motor was super smooth and revved nicely. Seating position will take some getting used to being low and long, so I'll fit the shorter links to raise the rear and get the rear wheel forward a bit to help.
My exhaust bodge lasted all of 5 minutes, so the collector needs to come off and I need to machine up a new outlet to then TIG on.
