400 four knocking noise.

<< < (5/16) > >>

buxtonmick:
Steve, just a point; in the vid the initial revs are at 1400 rpm not 1200  :)

mick:
I would try a fresh plug in that pot that's running cold that will make a difference when all 4 pots are running together, cheers  ;) Mick.

Lynx:
Thanks for pointing that out Mick :-[.

It's not the plugs. I swapped 2 plugs but the same cylinder was cold.

LesterPiglet:
No way was that bike revving at 1400. Something wrong with that tacho.

Sorry to state the obvious but until you get that cylinder running right you aint gonna get that knock to go.Shes dragging a dead piston.Can only be 2 things no compression or no fuel to it.
It really sounds like the carb to me.
Cheers
Bitsa
