Keeping my S2R 800 going and healthy. Winter small things, again ...

GENERATOR

New parts in a steady pace - it's normal, but this one is three working days before my tour of the Alps and Italy. Stressful.

The generator decided that it has done enough. Almost 180,000km. Measuring over the three yellow wires WITH wires connected gives results ~20V lower than when the wires are disconnected (I believe this is correct). Anyhow; last spring it was diagnosed this way when I ended up replacing the regulator. The result was 25V~ at idle and 40V~ at 3,000 rpm. Good enough.

Today 10V~  I discovered this because the battery lost it's charge while riding.

Ordered a new stator today. Maybe it's here Thursday. Maybe Friday. Just about soon enough

Well make the beast with two backs.  That's a bit exciting so close to D-Day.....

It'll be fine.

It'll be fine.

I think so too. I now know that I can do the job, so it's mostly about getting the part in time.

DHL flight delayed from Milan. make the beast with two backs. Ok - let me pick it up at the airport/in warehouse/customs clearance office? Anywhere that doesn't gamble with the driver's ambitions for this Friday? That's all right, Sir.

So, I picked it up at 11.30. Was at my friend's house at 13 and all included, finished at 16. Charging is as it should be.

Interesting thing:
it runs colder - ~10-15 degrees C. Maybe the better voltage improves/restores what the ECU really wants to do? It's having it's very own day on the Dyno Tuesday, We'll know more then. Workshop thinks the map is adjusted to get ok performance with the old injectors. Now, with new injectors AND proper electricity, it needs to be "reset".

Dyno day today

The old injectors randomly under-delivered 20, 30 + % which last year's map compensated for. With the new injectors from CA Cycleworks (even paired for perfection) it needed a new Dyno map. Today it got that. Steady, predictable and correct fuel delivery has to be good things The performance is back, anyway (it was already better, but now it's completely restored).

500km of Autobahn to test it tomorrow

Excellent. 
People don't realise how much injector efficiency varies which explains why many "canned" maps don't seem to work very well. The dyno is important in that regard.

[Howie]

Good to hear!

He also found leaking air through the spark plug washers.

Works really well now. More testing tomorrow. Now, drinks.

[ducpainter]

I told you it would be fine.

[stopintime]

20 - 30% fuel over delivery with the new injectors. The old map compensated for the old injectors' poor performance. Running very rich, but now remapped and fine.

I have a very noticeable stumble on the first few degrees of throttle opening. I hate myself for not turning around and have them fix it while I was there/close. I thought it would be ok when warm, but it didn't change. When I'm on the Autobahn I don't usually think about turning around...

Otheerwise it's much better

Well, after the July happiness things went from good(ish) to worse.

More about the "Revs falling slowly, uneven idle" Edited, so that thread is now merged into the long one (Keeping my... )



... and a compression test

Compression test:

When we had to accept that the TPS and ECU faults were not the only issues we have to go back/sideways into the mechanical stuff again. I think it might be a specific mix of eletronic and mechanical issues that, in certain rev/load areas, make a mess of things. The engine guy needs more info and wants a compression test.

Remember also that this engine was drowned last fall, while I was hospitalized, with rain/snow filling my air box, into the intake and ended up in the oil. It's not impossible that it did harm to parts. I still run old Pistal pistons (yes, I will repalce them next year).
