Re: Possible Electrical Glitch

Phil, I saw this about 3:30am the day after you posted it and thought since it corrected itself, it was just as you guessed . . . moisture that got blown away or minute corrosion that got pushed away. Thinking it over now, I recommend you pull the tank cover off and check the battery terminals for ...

Re: Battery Test

dbrick, Being it was so long ago, my guess is that the battery was replaced soon after. Your readings: "ignition OFF 12.3v, ignition ON drops to 11.5 , then over twenty seconds rises back to 12.3v. Cranking drops to 9.8v , and stayed there for the 3 or 4 seconds I held the start button down&qu...

Re: Alternator belt and a chirp

Photoguy, Your belt is definitely a little loose, most likely from years of wear. It squeaks on start-up because the alternator is in max output mode for every RPM it is at to replace the battery power of idle time normal discharge -and- the output voltage degrading big chunk of wattage the starter...

Re: Drain holes on the top of the valve covers ?

Soliton,
I remember considering exactly what you described, drilling drain holes at the low point of the seamless fin joining point. For some reason I did not do it, maybe that it was not needed unless we washed the engine. Can you show us some pics?

Re: Caliper Rebuild & Advice From Cyclerob

Oh yeah...How do the lines remove from the fender (black clips)? Going from doing this over 10 years ago :-k Look at the underside of the fender and you'll see a split cone shaped barb. Each half of that split cone is attached to one side of the brake hose clamp. With the fender on I believe it wil...

Re: Throttle cable adjustment.

Let me see if I get this right. Our barometers measure atmospheric pressure from a vacuum to 29.92 inches of Mercury (Hg Specific Gravity=13.633) a pressure that would be equal to 407.9 inches of water (SG=1.0). That also means that a differential water manometer is 13.633 times more accurate than t...

Hoof, Now that you have solved the problem of a severely overtightened oil filter, I recommend you go back to the factory BMW oil filter. Reason being is the BMW filter is made of premium quality components -and- this is unique when it is compared to all the other brand oil filters, BMW's has a sep...

Re: R1150 Swingarm Question.

InternetMechanic, What bike are you building and what model R1150 did the swing arm come from? You have so many unknowns here that you'll need to actually be hands-on with an R1150R to take your own measurements. I would say nothing is "on center" because it doesn't have to be. What's imp...

Re: No start in cold

I watched the voltmeter when I started it. It was at 12.6 and then dropped to 8.75 when it was starting. SunBeemer said it right: "That's too much voltage-drop while cranking; generally less than 9.75 volts indicates an electrical problem." Because the battery is only 2 years old, that wo...

Re: No start in cold

racurley, You have a 2003 model, meaning the electric starter went through 15 summers and 14 winters. Without any disassembly for cleaning/checking/lubing it can now generate less cranking power while at the same time drawing a lot more Amps starting current from what is likely a really good batter...

Re: Neutral Light

Hottech, It very well could be the bulb. Most bulb failures happen when the coiled spring filament breaks in a "burned thin" area, breaking the connection. Then the larger broken end filament waves around with the vibration, or not. When you raise the RPMs, that likely makes the filament ...
