Re: what is in this picture?

The transmission seems to be from something prior to say 1955. I think I can see the prongs that are on the output shaft which mate with what is called a Hardy disk...it softens the transfer of motion from the transmission to the drive shaft. Plus I don't recall seeing the clutch actuation arm stick...

Re: Cycleworks

From another forum...Dan is going through some things. He's had to move his shop a number of times. Also had to take a 9-5 job to help make ends meet. Also, it's a one-man job. So, things are not good right now. There's been mixed results. One person had his money refunded. Another person got what h...

Re: LED headlight replacement for H4

Greg Hutchinson (I think that's the last name) of ABC fame has designed an 800W alternator for installation on Airheads. The approach for his modification is for a person who might be interested in venturing all over the world with an electrical system that can be repaired anywhere in the world. Kur...

Re: Gen light

You gotta then wonder about the plugs on the other end of those three wires. On my /7, they're behind the diode board...the board has to be removed to get to them. When installing the solid mounts, I noticed that behind board connector was greenish with corrosion. I had Rick build me a new harness t...

Re: Motorrad Elektrik Ignition

Just curious...did the Mystik have advance springs? I know they transitioned to the bean can and hall ignition/electronic ignition, but am not certain about the springs. In any case, you can determine if the ignition is advancing too quickly. Just use a timing light and find the RPM at which the F-m...

Re: Oil in cylinders

Not sure what you saw regarding orientation of the reed valve, but when I replaced my round board breather valve with the reed valve in my '78 R100/7, I read/was told that the screw holding the reed in place should be placed in the 5 o'clock position or basically pointing to the right foot peg. I th...

Re: R100S occasional sputter and idle issues. Coil?

Sounds like the bad plug had some kind of spark energy threshold in order to fire. The new coil was able to more consistently meet or exceed that threshold for a little while. But if the coil sends energy down to the plug and it doesn't fire, where's that energy going to go? Likely it will bounce ar...

Re: Gen light

Be careful with the bulb holder...the delicate foil can break, creating more problems...it's no longer available from BMW. Fortunately, there's an aftermarket replacement. She and her husband, Airhead owners, decided to build a replacement. It's getting good reviews. http://katdash.com/ Kurt in S.A.

Re: R100S occasional sputter and idle issues. Coil?

The Dyna plate that replaced the original points plate needs a good ground against the engine. Pull the plate and clean things up to see if it helps. Probably will mean that you'll need to reset the timing since the donut that's clamped to the advance until will need to come off.
