FJ 1100 runs on 2 cilinders

[gijs]

I don't know how exactly to explain it but i am certain that its not the coil because i already swapped it and the connectors, everything over there points to the fact that the coils are OK

[gijs]

I thought I had it fixed, I put an extra wire to the battery ground from the coil.
but now it runs on 2 again.
when its idling it runs on 4 cylinders but if it comes above 1000rpm it runs on 2.

I measured the voltage on the ignition box, the wire to the coil and the + from the battery,  for the coil cylinder 1 - 4 the voltage goes to 0 if its not idling. cylinder 2 -3 coil the voltage stays about 3,5 volts.

could this be a faulty pickup?

The neutral light used to burn on contact and wile running, now it only goes on during starting

When mine was shooting flames from the pipe , was a small fray in a coil wire at the front of thd tank, but then i found the fuse connector plug had pulled apart just enough to make the bike run bad but still start ok. the plug is just under the fairing below the bottom edge of the gauges, i only found it because the cut off relay would click when moved,

could this be a faulty pickup?

Was you able to do an ohm reading on them?

[gijs]

the ohm reading is 168 and 169

[gijs]

the bike ran on 4 cylinders today but if i went above 4000rpm it would go bak to 2.
i found two wires with a green plug and they were stripped down and the copper was touching. if i pull the wires apart from each other then the bike wont start.
and if put hem together the neurtral light and de oil level light go on.

I remember that green plug but, I can't remember what it goes to. From your description it sounds like the side stand switch. Was your side stand up when you tried to start it?

sounds like your getting closer.

my bike does not have a side stand switch and I do not know were the wires from the green plug are for

[gijs]

the wires are from the neutral switch and the oil level switch.
and if if i touch them together then the bike starts and otherwise it wont even crank the engine

[fj11.5]

Wouldnt be a sidestand switch, the 1100,s dont have one

[Travis398]

[fj11.5]

Well not here anyway

[gijs]

Well I think I fixed it.
I found that the neutral switch had no bolts in it, so I went to the store and got a couple of bolts and screwed them in.
now the bike runs on 4 cylinders.
I went for a test drive and it still runs good after 5 kilometers.

and my bike does not have a side stand switch, its A FJ 1100 from 1984

Excellent mate,glad you found the problem,an :scratch_one-s_head:d it was an easy fix,, was about as much fun to find as my 84,s gremlin   :dash1
