Hello all,
Me again.
Again thanks for being patient. First K bike build for me.
I have read through the forums, and I’ve seen people similar with my issue, but unfortunately they are older posts so links / videos have been deleted.
I have a 1985 BMW K100
I have been rebuilding it, it used to not start
I have:
Replaced and tested the fuel pump
Flushed all coolant
Oil change
Completely re cleaned the gas tank
Changed all fuel lines
Changed vaccum lines
New air filter
All new NGK sparkplugs
I will paste a link to the video,
But do you have any guesses to what it could be wrong?
If I stop feeding it starter fluid through the air box, it dies
New 93 is in it
Choke has to be on for any sign of life (if it’s not, it will just tick tick tick tick like you can imagine)
I can hear the fuel pump fire on when I try starting it, I’ve also measured the voltage via a multimeter to the 2 prongs so I know that it is not the 4 pin connector.
Now it hasn’t been started in a while. I’ve *tried* the 10cc of motor oil in the spark plugs (although if 10cc really translates to 10ml like it says online I was way too scared to put that much in…)
Possible that there’s just not enough gas around yet because I replaced everything ?
Let me know
