I picked up a 1987 R4 in Porto, Portugal a few weeks ago. All is well except the speedo and fuel gauge did not work. I got hold of a replacement instrument cluster which is now fitted and works fine. The fuel gauge in the new unit also does not work so I guess I am looking at the float mechanism or some other issue.
Sorry about the preamble but I am getting there!
The old fuel gauge moved from registering nothing to registering almost empty with ignition on. The new gauge also registers nearly empty BUT higher up the gauge than the previous one. Then when driving the gauge registers 1/2 full when tank is completely full.
So I am a bit confused. If it was the float mechanism I would have expected no movement or at least the same movement in the 2 gauges. Before removing the tank and float mechanism can anyone point to another explanation? I don't want to take the tank out unless I have tried any other possibilities.
Any suggestions gratefully received.
Many thanks Ian
