I fed through some of the forum comments to Ged and he has changed the carb settings and moved the DMC to position 4. She pulls from standstill without any need for slipping the clutch and reving, so that problem solved.
Ged tested the tachometer and it is definitely reading high, at least 1000rpm, he recons tic over is spot on according to the sound, I just have to ignore the tachometer. Real surprise as both gauges were fully refurbed by Marcel last year. I understand he’s no longer doing any maintenance work so I doubt I can send back.
I’m going to meet The Sock and ask him to ride the bike and compare to his own. But hopefully he’ll tell me it’s fine and I just need to ignore the tachometer.
Thanks for all your help.
