Title: Sudden increase in fuelpressure
Post by: Enfield on October 27, 2017, 09:29:19 AM

Hi - a bit lost. My Brick is finally driving again K100 1984. Been driving about 20 km Yesterday .... everything was fine until I stopped for a hot dog.... When I started there was a "pop" and then fuel was spraying out between injector and rail... turned off immediately. Waited a while and tried again and ... pop now spraying from 2 injectors?  Engine was running fine while this was going on - no clogged injector.
 All gaskets are New and injectors have been cleaned.
 Fuel pressure regulator is also brand New !
Seems like the fuel can't return to the gastank...
 I was hoping  could point me in the right direction - all fuel Lines are also brand New.
Regards
Christian

Found out what was wrong...I am a total novice on injected engines  and been working on and off with the K...... simply forgot the small "locks" on the injectors....

You're not alone I think a mate did this. He had his injectors serviced and they leaked, I asked him if he had put the clips back on, his answer clips what clips. Later on I asked him what had caused the leak he said faulty "O" rings, I'll pretty well lay odds that he forgot to put the clips on. :hehehe

The most important step when working on any motorcycle is to look around to see if you have leftover parts.  If so, stop what you are doing and find out where those parts attach.

Yes - normally I do that. I took the brick apart and had frame etc. powder coated and started putting everything together over the summer - planned to have it on the Road by the end of summer....but then the project was abandoned for a period of time ..... my father went away...
 And now I been putting it together a bit too hastily as I just wanted to have a Day or two of riding before winter.....i managed that :-) ....almost...
and now it needs to be perfected over the winter! I do have some top end power loss and other small things
