Re: Refurbishing valve covers

You might try using Rub 'n' Buff colour 'Silver Leaf' after cleaning up your Valve Covers to see if the finish suits you. Apply sparingly with a toothbrush and buff to required shine. Works well on alloy such as wheels, fork sliders, engine/gearbox casings, swing arms and final drives and lasts well...

Re: Modern Diagnostic Testing

If NO voltage is read, then the ECU HES Input circuit is a 'Pull-Up' design. NOT TRUE!!! :pale: Or should I say, only true if the ECU trigger input is referenced to 0 volts. It could be referenced to line voltage (unlikely) or to an internally generated voltage somewhere between line and 0volts... ...

Re: loss of spark

That sounds promising!

Is the fuse in the Ignition circuit?

The HT Coil is suspect, so Dave MUST fit a NEW HT Coil before powering up the ECU!

Re: loss of spark

Is the pin with the black arrow the spark output pin? The spark output is on the ECU Connector pin #35 tagged Z1. The connector pin numbers should be partly marked on the connector - probably best seen with a magnifying glass and usually only the first and last numbers shown for each row. You can d...

Re: Weather & working on the bike outside.

What about using a cheap Summer gazebo (preferably with sides) as a temporary 'pop-up workshop' to enable you to work on the bike outside in the Winter?
Tie it down well with extra ties though! #-o

Hi Dave,

Thank you for the update and thanks to Mjolinor for taking on this task. :smile:

Hopefully Mjolinor can find out if the ECU is indeed kaput and what is wrong.

Re: Condensation in speedo

Water inside the unit could cause serious problems if it froze during the Winter. A small hole around 3mm at the lowest point when mounted should allow leakage to drain and some air movement inside the unit. If a larger hole is made then there is the risk of dust/grit getting inside. If problems sti...

Hi Dave, On your R1150R (and the RT), the Kill Switch cuts the +12v from the Ignition Switch to: The Starter Relay. The Motronic Relay. The Fuel Pump Relay. If the Kill Switch was faulty (open circuit) you would not be able to crank over the engine so it must be OK. The Motronic Relay is the critica...

Re: charging

Hi Neal, A high Alternator voltage (16v) at the Battery can also be indicative of corroded battery connections. Corroded Battery connections can also appear to be a flat Battery as a high load e.g. Cranking or Headlights, will cause a large voltage drop across the corrosion. Clean the Battery termin...

While the two manuals complement each other, the one used most often is the Haynes manual. Unlike the Haynes manual, the BMW Repair manual does not contain any wiring diag...

Re: Leaky caliper

Hi Howard, Although you posted that the leak is coming from the piston area and not from between the two halves of the caliper, it still may be that the leak is coming from between the halves. The O-ring seating between the two halves can be subject to corrosion as I found on my own R1100RT. Such co...
