So, I’ve now done a few thousand clicks aboard the VF, and it is endearing itself to me.
However, even the most carefully stored 30 year old bike can develop a fault or two and thus I have discovered with the battle cruiser.
Heading into work last week, it started getting sluggish, like it wasn’t running on all four, and so I started to pull in off the motorway.
I managed to get it off onto a slip road and into a populated area before it stopped.
It would appear as if the positive battery connector had worked loose and there may have been a bit of arcing. Bugger!
Anyway, I managed to get it started with a new battery and thought I had a lucky escape. Halfway home, it did the same again and this time it was terminal. Home it came in the back of a truck.
When I managed to strip it down, it turned out the fuel pump was knackered.
I got a new pattern one, but one without the inbuilt elbows on the pipes, so I had to resort to a little creative plumbing. I also took the liberty of changing the fuel filter.
I put it all back together and it fired up after a few stabs of the button.
Away I went to work the next day, happy with my handy work. I got about a mile and half home before it stopped again, fuel starvation!
At home once more, I went through everything thoroughly and the fuel cut off relay was dead.
Down to the local breakers it was, and no joy on getting a CF304, but they did have a CF318, from the early CBR600 and VFR750 models. As the fuel pump I got was supposed to work for any of these anyway, I figured it couldn’t be that far out, and the connector is the same.
I tried it and away she went.
This is a good thing as the CF318 relay is far more available than the CF304, which is getting pretty rare these days, at least this side of the pond.
PS: Apparently there are Yamahas that use the same kind of fuel pump with the elbows, so must look further into that.
