Thread: A bit of advise please

Surely there wouldn't be big differences in the water channels on each side of the block? Anyway, fortunately on a motorbike with carbs this is easily accounted for by adjusting the jets/needles on each carby independently until neither runs rich.

Usually on bikes it's the clutch side that tends to run hotter.

for the plugs sooting on one side.......they are actually cleaned on one side from the fresh cold fuel charged hitting them.....
the cold wet fuel de-carbs that side of the plug........



as for the rangie.......could it simply be in limp mode......?
