Need a little advice on massy 390 clutch
Installed a new clutch a few years ago at the time of fitting had to use longer bolts on clutch fingers to get it to clear properly now at end of adjustment can't adjust clutch to clear anymore usually when plate is worn pedal rises and knee is behind ear so adjust back, this is going other way would I have a problem with thrust baring or wrong one fitted at clutch and and plate change? Any ideas

Could it be the cable is stretched? Pedal on our 390t was getting lower n lower kept adjusting it back then one day it went ping. Was only holding by one or two wires.

Yes if its cable type it will have stretched.
A build up of clutch dust on a worn clutch will cause drag but shouldn't be an issue with a new clutch.
Did you skim the flywheel consequently moving the clutch further away from the release bearing.
Fork worked loose on cross shaft?

A complete new clutch assy will be set up and the toggle bolts will have a blob of paint on them, so just fit it.
If you want to check I have the measurement.
