Re: Electronic ignition and a condenser

With the Dyna III, the advance unit is reused and the points plate is replaced with a new plate that has the Hall effect sensors on it.

Re: Have any of you seen anything like this before?

Have never heard/seen that before. Seems to me that the surface area involved is pretty small to get any great oil cooling. Only about 1-2 inches of the bottom is dipped in the oil. The oil would have a high heat transfer, but the rest of the rod is in air and likely wouldn't transfer much heat. I g...

Re: Center Stands - R25/3 and R26-R27

Way too tall. I don't know the differences though. Part numbers are different but the microfiche pictures are pretty generic and don't show any differences.

Re: Electronic ignition and a condenser

And this is an R90/6? Not sure what an R9/6 is. ;) No, you don't need a condenser with a Dyna III. I have that system on my /7. But I leave the condenser in place for the odd chance that I need to switch back especially in an emergency. I carry with me the old points plate. Could be that the condens...

Re: Center Stand Lean?

So about the bike lean... The center stand rotates on the two bolts that attach to the frame. If the stop-ears are different in profile, one of them is likely hitting the stops first but that isn't enough to hold the bike's weight. So, the weight settles until the second stop-ear makes contact. Seem...

Re: Fork Leg Questions

FWIW, on my /7 with only the one caliper on the driver's left slider, the axle comes in from the driver's right and the spacer is as you show it between the slider and the wheel. The nut that secures the axle is on the driver's left. I would think that works for all front ends of this era, regardles...

Re: Fork Leg Questions

So, does this help any? #8 is needed as a spacer. Group #12 is the what deals with the axle diameter differences. This is for an early '74 R90S.

Re: Center Stand Lean?

Following the piece that I've pointed to with the yellow arrows. This webbing goes up around the top of the stand and that is what contacts a frame part to stop the stand from going any further. Do you see any wear or bending at the very top of this webbing? I'm guessing that is where the problem is.

Re: I need sympathy
