Question about 1984 BMW K 100 RT

1 Answer

84 k100rs runs poorly hard to start at times no power over 3000 rpm cuts out on road after 30 seconds running, some times hitting fuel tank brings it right for short time. have checked fuel pressure40 psi but did show signs of pulsation at times, dismantled pump looks good. occasionally goes perfectly but then will play up again without warning.have checked relays, and connections both inside a outside tank, tank connector not good but does not appear to be the problem.suspect it may be the fuel pump itself but not convinced.

Problem could be throttle sensor situated on left side of bike below fuel tank, your symptons appear similar to mine of past. Cured mine by fitting new sensor.

A few things come to mind.
After a fuel failure like that it is possible you have fouled the plugs, causing a hard start, rough idle.
Also, if it was run any length of time in that state its possible the catalytic converter has become slightly clogged not allowing the rpm's to climb.
I would start with a quick check of the plugs.

It is normal for the pump to run for two seconds when first switched on to pressurize the fuel system. It will turn on again when cranking and while running. I would still suspect the pump given your symptoms, however other problems could also give you the same symptoms. If it is the original pump from 2002, or more than about 7 or 8 years old, I would definitely replace it, and the fuel filter. Often the pump will go intermittent. I had one that I could restart and get down the road by hitting the bottom of the gas tank a few times!

I will be driving down the road about 65 mph and all of a sudden my truck will just sputter and then have hardly any power with rpm needle jumping from 1000 to 1500...cannot go over 30 mph. If i stop and...

Sounds like a fuel problem. I'd start by changing the fuel filter and running a can of Sea Foam Engine Treatment through the engine. With at least half a tank of gas dump half the Sea Foam in the gas tank and the other half in the crank case.
If this doesn't fix it check the fuel pump, don't just decide to change it or have it changed they can be rather expensive (depending on engine and model).
If the fuel pumps checks good and it's still happening you'll have to start looking into distributor or timing chain problems (usually not intermittent).

Hello ,your fuel pump is losing its prime and running back into the tank.Two things could be wrong either a bad fuel pressure regulator or the fuel pump itself:)
