    Now back to my clutch. I have never done a clutch job in anything before, so my 1971 BMW R75/5 is my first. Now that I am retired, I am finding the time to do these jobs.

    I am about to attempt my very first first clutch job ever on anything. My R75/5 clutch is gone to the point the bike is no longer ride-able, not even to a local BMW dealer. But I wanna try it myself...

    I have dealt with Capital many times. Back in the days they used to send catalogs via snail-mail to all BMW owners.

    All back in the 1970s and 1980's. I didn't know they are still in business. I...

    That's the first time I've seen dual plugging with stock points. Nothing wrong with that setup, but I would still prefer to not have any points to adjust at all.

    Of course, you still have the...

    The difference is not two or four spark plugs. The difference is the D35-1 or D35-2 Dyna setup.There's an added pickup coil on the cam, which is in sync with the side it fires. Both the D35-1 and...

    Sorry about that!

    But the D35-2 can be configured to use only two plugs total with no waste spark, by simply grounding out one of the Dyna HV ignition coil spark plug wires on each side and only...

    One more thing PROVES there is no waste spark. Read what it says about the tachometer in the bottom schematic.

    That's because at 4,000 RPMS the tach will only shown 2,000 RPM's. Can you all guess...

    Did you read the part above on the schematic about it "firing the cylinders sepeartely". That means there is no waste spark in the D35-2.

    It makes no difference in waste spark if there are four...

    You proved my guess was correct! The bottom schematic gets rid of the wasted spark unlike the top configuration.

    I am not sure if that proved anything. You have two pickups, so it will only be matched exactly to every other firing. Have you ever checked the static timing (engine NOT running) to see if there is...

    True, but every 180 degrees, all four sparks can be at a different time than all four previous sparks, because of the extra pick up. Points only open once every 360, but there are two pick up coils...
