Great, the same as the the one I just removed from the sample bike, and the purchasing records going back to when Renolds could no longer supply the kits.
This issue does not occur with OEM pieces/dimensions.
What are Norton Mk3 owners doing?
Precisely, so you've replaced incorrectly dimensioned parts with more of the same, but you bought an original plunger kit so why not use it on the top run?
This particular Mk3 owner is still happily using original parts.
I found one set of my tensioner components. lengths, wire size and 26 coils all same as LAB.
Any reason not to shorten the nylon spacers by the .150 difference in depth of the short bore?
Air purge and bore oiler bleed hole will then align roughly to the top of the nylon spacer.
Then shorten the nylon piston another .116" so the 29 coil long spring will not get coil bound.
All in all, mainly a slightly stiffer pair of springs against the pistons/chain.
Top tensioner is the quick reacting piston and the bottom one get slowly filled from the top tensioner and is only slowly allowed to bleed off through the air/oiler holes. Hope the tiny fill hole never gets a bit of grit or black sludge/residue from a fiber friction plate.
Started to formulate a theory on the detrimental effect of the black sludge on the sprag performance.
