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.

Changing the rear drive oil

November 29, 2008

Yet another “R” tutorial 😀 Well, it’s understandable from my point of view, I really love the R engine. As I see it, I would recomend changing it while you do the engine oil change, just to be on the safe side, but most people do it at every other oil change. But if you’re already soacked in oil, why not do it? It’s only about 20E/liter. Just basic maintenance procedure.

Bleeding the Integral ABS

November 29, 2008

A very detailed tutorial about bleeding the servo integral ABS brakes. It should work on all R 1150 and R 1200 bikes.

What happens:

– brake overheats during extensive heavy braking (like going fast on twisties or on the race track)

– brake levers feel spongy

– brake loses power

When happens:

– brake fluid too old (recomended change every 1 year, to be on the safe side)

– riding for prolonged periods of time in rain or wet environement, like in UK (brake fluid absorbs 2% moisture per year through hoses/brake reservoir; when it reaches 8%, it will overheat)

– problems with old o-rings or brake lines

Fitting a GS Adventure tank on a basic R 1200 GS

November 19, 2008

Going to Africa or Siberia? Maybe planning an iron butt ride? Or just wanting to cover many km without the hassle of stopping to get gas at every 300km? Well, if you’ve got a R12GS and some money to spend, this is one solution. Just get yourself a GSA tank, some tools and a few hours of work and you’re done. This Adventure, 33 litre tank is going to give you between 450 and 600km of range, depending on speed and style.

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.

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:
