Hi all out there. I have been reading the latest post re the non-start with interest but it is not solving my problem. I think my issue is a little more basic.
Background is that I have previously owned a K75 and assorted other bikes. I have been bikeless for 4 years and it hurt a little too much!
I got hold of a 1986 K100 RS 2V and have spent the last 4 months pottering and fixing it up It was a bit sad cosmetically. It ran well on the only trip I made from sellers home to my home. I started stripping it right away thinking it would only take a couple of weeks.... I have replaced filters, plugs, oils, serviced alternatr, starrter motor switches, spline regrease etc etc etc. I live in a place called Broome in northern Western Australia. The nearest BMW mechanic is 2200kms in one direction (Perth) and 1900kms in the other direction (Darwin). There are no other K100 bikes in town I can compare this with...
I also recently had it repainted. The tank had some fine traces of dirt etc in it so I washed it out thoroughly (with water) and rinsed with petrol prior to painting. It had been stored inside a garage with fuel in it prior to this. Put it all back together last weekend (new fuel filter)and tried to fire it up yesterday (Saturday in Australia)
It cranks over strongly but will not fire up! Now for the questions:
Q1. Have I got the fuel lines replaced correctly? On the front LHS of the tank there is a fuel line that goes into the inards of the bike. Next is the 4 cable plug and behind that is the second fuel line whic has a thick foam protection piece on it and goes into the fuel rail. ARE THESE CORRECT?
Q2. When the above fuel lines are disconnected: a) fuel freely flows from the front pipe. b) nothing comes out of the second pipe. If I blow really hard on this second line I can hear a little air going back into the tank???
Q3. Is the fuel pump working? I have checked the fuse. In the "other" article it states you should be able to hear the fuel pump operating when you hit the ignition switch. I don't "think" I can...How loud and noticible should it be? When I disconnect the second rear fuel line and hit the starter button should fuel pump from this line?
Q4. Can I check the fuel pump in some way without removing it from my freshly painted tank? i.e. can I apply voltage directly to the electrical plug on the tank? If so, which pins are they? In the schematic diagram the two wires from the fuel pump go to the four wired plug and change colours...
