Assembly lube. It seeps out the first few times the final drive gets hot. Clean it up with something (simple green, etc) and it shouldn't re-appear. Mine had the same thing.

Whew! Thanks AC! I was startin' to have Euro-bike flashbacks.

My bike has about 2500 miles on it, and has been washed about three times. So, I figured there was no way it was something that should be gone already (assembly stuff/preservative).

In fact, I was already diggin' thru the brand-new service manual, that my Brother gave me for Christmas. And, I have the mechanical aptitude of a potato. So, that's when shit starts gettin' real interesting, in my garage.


Thanks again...

You'll see it again if the splines get overly lubricated at mx or tire changes too.

So my flash will probably be US spec. On top of that, having spoken to them, they are a bit unhappy with the results obtained when they flashed an S10, so they are looking at removing the O2 sensors and rejigging it. Apparently one bike ran well enough but then started generating fault codes. The bike may have been modified in other ways too (exhaust/filter etc). The off idle fueling was the problem IIRC.
I was phoning international so I did not go into detail but I arrived back in the UK yesterday so I will get better details when I go and see them in the New Year. Fortunately they are only 30mins drive from me. It is likely that I will lend them my bike to do some testing with.

I will up date when I know some more.
I handed my bike over to the engineer on Saturday. He will likely keep it for a month while he designs and manufactures a work around for the O2 sensors. Apparently what happens (and this is a UK bike with a different ECU and we have different fuel here) is that with the US ECU Unleashed flash, the ECU kind of figures out that there is a difference on the O2 sensor to what it normally receives and compensates for it. It remembers that compensation and then compensates again...and again etc, until the engine fault light comes on.
Apparently this happens with a lot of ECUs but on most bikes (i.e.older) the problem is not progressive and he also states that often, production racers have the same engine light come on and ignore it (he tunes race bikes for a living).

What he is doing is designing an electronic unit to interface between the O2 sensor plug/socket. He showed me one for another bike, it is a small circuit board in a box with a plug and socket extending from it. Unfortunately the S10 needs 2. On a lot of other bikes, (i.e. the TDM850,) the O2 sensor can just be disconnected, but the S10 gets the hump if this is done.

This is what he has got so far.... It probably (understandably) mirrors the ECU Unleashed one.

Interesting and raises the question of how Diapason and OTR manage to successfully reflash EU-spec ECUs without needing the interfaces. Has he checked into that?

I have no idea if he has, but I would feel it unlikely as they are competing companies and are unlikely to discuss what are essentially, company secrets.

I was thinking more along the lines of him scrutinizing an ECU that has been flashed by the competition as he should be able see what changes they've made. In any case, I'm about as far from an expert as you can get but it seems like he is rebuilding the wheel with added complications. Just a bit surprising considering he has the resources of ECU Unleashed at hand.

Still interested in the outcome though...

That's interesting Ray, I didn't know that. I suppose that that may be why I haven't noticed the famous "off idle stumble" that many others have complained about. (Either that or I'm too ham-fisted to notice!)

The ECUs are different but.... UK bikes have a matched ignition key with the ECU whereas US bikes do not (I believe they have conventional, un-chipped keys) so the differences may just be for the ignition key aspect but in all honesty I do not know.

You make a valid point about the "ham-fisted" thing. If you ride these bikes hard you will not notice it. It is only when ridden slow that the problem manifests itself. Last month I rode slowly with some Harleys and it cut out a couple of times. The other problem (for me anyway) is when riding 2 up. The gentle throttle use, especially in town/traffic is lumpy.

Anyway, where the hell in Guernsey can you ride hard ????

That thought crossed my mind until I saw his setup, we will see.

I find the O2 sensor info interesting. I have a US bike with an ECUnleashed flash. My O2 sensors are in a box out in my shed. AF1 racing told me that after the flash they were not used and that the software was tweaked so there would be no error codes after removing them. I have ridden thousands of miles with them removed. I know that Jaxon has removed his also. YMMV

I felt the same way, till I did the clutch mod. Boy was that an eye-opener.
