I recently used nickta’s very useful notes to change my 907ie fuel filter. Here a couple of additions and pictures others may find useful. When reaching in thru the tank opening, I used my right hand, then tilted my torso way, way forward. This straightens out your wrist and lets your fingers have b...

Update: Success !! I tracked down MAE thing, yeah, I think it’s AKA the power module. It is located on the plate holding the V regulator and the relays, sitting below the regulator. I unplugged/reseated each connector going into it, and loosened/tightened the nearby ground. Everything looked ok, not...

The coils are stock. The horizontal coil from its appearance and markings is the original one. The vertical coil is a replacement that I installed during this troubleshooting process. It is the OE type, mentioned previously being sourced from Gotham Cycles, and the resistance numbers above were for ...

Update: not a good news update. I sent the injectors to Injector Repair LLC, Glenville, NY, and spoke to owner “Jim”. I was hoping he would say the vertical cylinder injector was wonky, but he said they were working perfectly. They did their standard cleaning, new o-rings, new screens and before/flo...

Sorry for the late reply Higgy.
The new coil measures 0.5-0.6 K ohm on the primary side. (My meter only has a K ohm setting) The secondary is 6.92 K ohm.
From another post, these numbers are appropriate.

Update: I sourced a new coil from Gotham Cycles, installed it for the vertical cylinder, no improvement. Then I ordered a set of plug leads from Magnecor, initially 1 wire was too short, so I got that sorted with them. The replacement wire from Magnecor arrived yesterday, things reconnected etc. and...

Looking good Bill, well done. She’s a rare bird that you married.

Fvee3 - I can take a look in my tank, but I’m away for another week. Maybe someone can get you an answer earlier.

Higgy, I didn't check for water. But with it apart some, draining the tank will be easy to do. I've thought about the plug wires for sure, and coils. Something I did yesterday was to start the bike, ran it for maybe 5-6 seconds with the idea to touch the horizontal and vertical exhaust pipes right o...

Here’s a link to a YouTube video that my daughter helped put together. Part video clip and part audio clip.
Take a look and a listen.

Hello guys, my 1992 907ie recently (a week ago) developed a significant engine stumble. I’ve owned it 2.5 years, it is usually a reliable starter and steady runner. I’ve read many posts here for troubleshooting, have done some tinkering but I’m getting nowhere. It started normally last week on the h...

I 2nd your comments Stepaso, I’m about 2 years in on a lithium installed in my 907ie. The crank over speed is wonderful.

Hi Gary, I’ll take these misc. parts you have. I’m close by in MD.

Bump on the manual for sale, it’s still available.

Mother Nature granted a 60F day, so out with the 907ie for some ethanol free go juice and a 30 mile ride. Might be a while before another comes around.
