Outer Limits 4x4 Board

A mate of mine has an old cruiser that has just developed a knocking noise in the motor [2f] its definatly not bottom end sounds more like a drivetrain noise,have adjusted valve clearances, no difference.Am thinking it could be a lifter,cam bearing? any advice would be appreciated.

ps. it only does it under load

my uncle 2f did the same sort of thing what happened to his was the crank pulley bolt had come loose and the woodruff key had come out. wasnt total stuffed. new bolt washer and key and it fix the problem

How long is a piece of string...

This is the question is it not....

You see my point...
