I’d go with that Mr Nick, but I’ve got a hang up about sump plugs, they’re tucked away out of sight and if they do decided to say goodbye, well I guess we all know the consequences.
It’s never happened to me, but I have seen the results elsewhere.
Got my son living at home at the moment because of the lockdown he’s a senior tech at a Ford Dealer (hence my access to his fancy torque wrench), he echoed what everybody else has been saying - use feel, which I’m OK with. Just as an aside some of these new Fords have plastic sumps, sealed heads, and gearbox’s that a coded to the rest of the car (if they fail it’s a throw away). Jeeez I hope bikes avoid going down that road!
