I`m posting this across several forums in the hope that someone may have experienced the same symptoms
My Monza fires up as normal and for the first 5 miles runs extremely well but then just like a switch one cylinder goes AWOL, not even a cough and a fart, however once the revs have risen to 4000rpm then the offending cylinder kicks in again (just like flicking a switch) and the bike behaves as normal. This is my third V50/3 bike so I have some experience but this is doing my head in, to date I have checked/changed the following
points and advance mechanism checked
condenser changed on offending cylinder
carburettor stripped and cleaned three times
coils changed including HT leads etc.
new plugs fitted
tappets checked
fuel taps removed and cleaned
fuel tank vents checked
While it is running on one cylinder there is absolutely nothing from the dead side but it does sound nice for a 250 single
This is driving me bonkers not least because I have to ride the bike for 5 miles or so just to see if my latest solution has worked
This bike is a recent rebuild and has done less than 100 miles since so 4000rpm would be my optimal for running in
HELP
