Thanks, dropping that extra jackshaft at the back really seems to have helped the engine power-wise. Been playing with the carb a bit this morning and it's finally back to the point where i can get scare myself a bit going into the turns. Pulls 3rd gear strong from lower rpms, which is really a first.
Blew the master link apart 2 times, it was catching a bit of weld on the front jackshaft bearing hangar (about 1/2 mm clearance on the wider master link) and the idler sprocket was a bit off, had my spacer on the wrong side.
Just redid my net fasteners (replaced the clips with springs) to get rid of the rattles ... and shaved another 3/4 pound.
If you ever have the thought that taking the time to cut or grind off excess isn't worth the effort, stare at it long enough to see just home much extra metal you're really carrying! On these mods and homebuilts, it ends up being a lot as they get developed.
