Oilhead misc parts

December 5, 2008

As you’ve probably seen already, parts directly from BMW are expensive and there’s a delay between the moment when you need it and the moment when you have it. Therefore the guys at bmwsporttouring.com established a coprehensive list of alternate or original parts that will work on your bike, be it for regular maintenance or emergency repairs.

Motronic 2.2 DIY diagnostic tester

December 1, 2008

This is one of the best tutorials I’ve ever put my hands on. You see, all BMW injected bikes have a diagnostic plug. The catch is that a proper tester is about 600E. But you’re far away from civilization, far away from any BMW dealer, you don’t have the tester at hand and your bike just quit going without any warning. You still have to push it to the nearest repair shop, but, at least, you have a clue on what might be wrong with it. The solution is very simple as you’re supposed to carry a multimeter with you at all times, just in case.


I’ve already tried it on my R11. The tutorial works for all Motronic 2.1, 2.2 and mechanical injection bikes. Should also work on Motronic 2.4, but I might need your feedback on it.

Setting the throttle position sensor (TPS) on oilheads

November 19, 2008

This is a maintenance procedure for all oilheads. If it’s locked securely into place, it shouldn’t budge, but, from time to time, you could just check it. On the other hand, I don’t know why would anyone want another position apart from the factory standards.


R 1100/1150 ABS Reset

November 15, 2008

Maybe your ABS doesn’t start in the morning. Or maybe you’ve just taken a spill and the least you want now, with all the adrenalin running through the vains, is not to trust yourself in the braking of your motorbike. But it’s a quick and easy way to restore your confidence. Use this to troubleshoot rather than find the solution as the ABS not working (and flashing it’s annoying lights) may come from other problems, like an old battery or different-from-the-book ABS sensor gap.

What happens:

– dashboard flashes alternatively the ABS lights when running

– wheel locks under heavy braking (try the back wheel so you don’t crash)

When happens:

– when taking a spill

Oilhead Fork Replacement

November 14, 2008

So you smashed another fork seal… Not a problem. Just try not to do so much wheelies or trail riding behind another motobike. Oh, and it doesn’t affect the damping as all suspension is carried out by the shock, it’s only used to lubricate. Make sure the oil doesn’t get on the brakes.

What happens:

– one of the forks leak

When happens:

– riding a dusty forrest road; it’s exacerbated if you’re not the first rider in the pack, but, obviously, a Bimmer is always the first ( 😀 )

– doing wheelies

– running bad tarmac roads for long periods of time

So there’s the tutorial:

R259 Hall Sensor

November 14, 2008

Since that was my original problem was this one, I seems obvious to start with it. And it’s a fairly common one for this engine

What happenes:

– bike stalls for no reason, either at idle or at speed, like hitting the kill switch; rear wheel still turns

– difficult starting

– no spark and no fuel pressure

– tacho might bounce

– bike generally restarts if dry and left to cool for a few hours

– bike seems to run on only one cylinder up to about 4000rpm, has hick-ups

When happenes:

– bike is hot, either because of traffic or very high ambient temperature

– bike is wet, either freshly cleaned by means of water hose or rain

The procedure to get you out of this mess can be found here:
