Question about 1995 BMW K 1100 RS

1 Answer

Bogging Alright this bogging down while sitting at stop lights is getting annoying. Its been doing this when it gets above 194 degrees for the last year. Every time I replace the plugs it goes away then after about 3,000 miles it comes back (plugs look fine nice and clean). Talked to my LBS and he said the gixxers when they get over 194 degrees dumps more fuel in the engine to try to cool it off. I have had this bike since the start and it didn't do this then just with in the last year. Is there any way to tell the computer not to dump as much? Or is there another problem we are not seeing.

I need to know a few more thing though. Does it die when it bogges down or just drop in rpms? Does it bogg when you try to give it gas or not? By what you have said I would start with looking at the choke first then the fuel pump. Or the relays that control them. You see if you add more fuel to the mixture after the bike is hot then it will kill it and you could not go without killing it. So who ever told you that when it is warm more fuel goes in to cool it down has no idea what they are talking about. I worked on a R1 about a year ago that did the same thing and it turned out to be the starter relay because it also controled the choke and fuel pump.

When u service it, did u do a complete service to clean all possible areas gunk can sits on, such as your petrol tank, fuel lines, jettings, float bowls, change your old air filter? Sounds to me it is still quite dirty and restrictive. Do a complete fuel line cleaning service and try again. Cheers.

My 06 gsxr750 heat up really fast. Temp stays around 190 while ridind. When I stop temp jumps up to 219 and the fan cuts on. Antifreeze level looks good and hoses are tight. I can feel heat coming from the...

My bike is the same, It runs at exactly 100 degrees more than outside air temp, and at a light, or in stop and go traffic, it will go to 212 when the fans come on. It is like sitting on a blowtorch. But that is normal, Harley's run a lot hotter than that. Mine is an 02 S4 Ducati. Been like that since new. I avoid Daytona, the worst place on earth for bikes. They have an average of 1200 burned bikes every year. Sitting in traffic for hours, not moving. And the noise, my lord, get a stinking muffler on that pig!!! Hope this helps.

This sounds like water condensation. Drain the carbs and a cup of gas from the tank and see if that solves the problem. If no joy, check the filter screen (inside the gas tank) mounted on the gas valve. A plugged screen may not let the gas flow freely to keep up at higher speeds. If still no joy, clean the carbs.

Next time it happens, pop the gas cap and see if the problem stops. Can you hear/feel air rushing in when you open the cap? If you can, you have a clogged gascap vent. You can try to take it apart and and clean/fix the one you got, or just buy a new cap.
