Title: wrong gear of sorts
Post by: midden on 05 October 2013, 03:58:32 pm
So you come to a junction, slow right down and forget  dropping down the gears then accelerate in too high a gear (or low whichever it is :o )  do you get a horrendous noise presumably from the chain

The engine would bog down and stutter but the only reason you'd get chain noise is if its too loose and you're only noticing it because of the 'quieter' engine noise

Sometimes if I roll out of a junction were I've slowed but not stopped in too high a gear or too few revs less than 1500 say, then yes I do get a bit of noise from the chain / engine.  I usually just change down or keep the throttle gentle untill the revs increase.

that would be the same then.  kind of hard to describe the sound other than kind of grinding

I'm not sure if I actually hear anything but I can definitely feel it.

Lugging. Sounds bad and it does nasty things to your engine.
Plain bearings rely on the surfaces moving past each other to maintain the oil film (like aquaplaning)… too big a load at very low revs means the pressure can exceed the film strength.
