Keith, what airfilter setup are you using and do you still have a fuel pump? The wiring mod originally came from the P750. While the wiring design of the 906 with the main power running through the ignition switch is the same at least the coils seem to be of a better quality. First thing to do is me...

The parts catalogs are not 100% reliable. It's possible that early M1R forks had that "ferrule" in both legs and later didn't. If you look at the 906 parts catalog (which was probably printed some time after the one of the P750), it shows that part only in the left fork leg. If that Öhlins...

I'm waiting on a carb kit for my 1980 Vespa, and that goes back together first.

I'm currently finishing a Malossi 221cc engine for my '85 Vespa T5.

As expected the voltage is way too low. Probably at a higher rpm there would be enough voltage for the front cylinder to get spark and run as well. Ideally the voltage at the coils should be the same as measured at the battery. The culprit causing a high resistance is often the ignition switch. Do t...

Looks like it caught on fire.
It looked different a couple of years ago: viewtopic.php?t=2165&start=45
Are those mirrors from a 999? They just closed the opening between mirror and fairing?

I've seen 906s with the 907IE front screen and vice versa so that's compatible. Rear sides and taillight fairings are interchangeable although the taillight fairing piece is shaped a little differently around the lock. That leaves the front side fairings. Here I can only guess that these are the sam...

I should have sent it to Finland then as the rebuilt cost €360 here. Also the spring isn't available anywhere in Germany. I'll have it powdercoated.

Often what seems to be a carb issue turns out to be an ignition issue. You say you have spark and that it runs properly with starter fluid. As that ignites very easily the spark may not be strong enough to properly ignite the fuel. Therefore measure the voltage at the coils (orange wire) with igniti...

A really clean looking bike. Nice job.
Two comments tho. The center stand seems to be hanging a bit low and the rear axle excenter is upside down.

It's been a long time since I've posted something on the forum the last time, but now I have a question. Does anyone know where to find the spring 1099-05 and the hose 1042-04? (preferably within the EU) I just had a DU-508 rebuilt but the shop who's an official Ohlins partner says they can't get th...

18 tooth cam pulleys from a 851/888/916/748 will fit on a 750 Paso/Sport, 906 or 907IE. The 20 tooth ones from the Teastastretta won't. Most cam pulleys, specially aftermarket ones don't have the outer flange.

Good idea regarding Shindengen, Gert.

Over the years the glasfibre packing burns out and is blown out the exhaust. Be sure not to stuff in the new material too strongly otherwise the exhaust will remain loud.

Hard to say what model reg/rect it is. I searched through pictures but didn't see one with that order of wires (two green in the middle and the yellow on the outside)

You can post a picture of the reg/rect. Maybe someone can identify it.
I'm wondering about the cable with the cut red wire. Is that an original one? All the wiring is in hoses while that is a 3-wire cable.
