Turning Wrenches / Re: Testing for Charging Issue...
Last post by BlueR32 - October 12, 2026, 04:34:02 PMMore progress: got the stator mounted and wiring routed. Just set the gap on the sensor. Chuck Quenzler's guide to installing the Vape has been most helpful, but I really did not want to drain the oil and remove the clutch cover to lock the crank so I did a search and came across this:

What a great idea! I happened to have an old plug that I had modified some time ago into a dial gauge holder so with a spacer and a longer allen bolt I made this piston stop.

Turning Wrenches / Electrical Woes
Last post by SmokeAddicted - October 12, 2026, 02:31:07 PMI'm aware this may be a lost cause over the internet, but I'm trying anyway. These are all new symptoms. I have a Dyna S ignition with Economy Cycle coils. After 6 days, I'm not sure where to look anymore. I know very little about what has been done with this bike by previous owners. The electrical system is as it was when purchased.
Current symptoms is the bike has spark from both coils when turning the key to the OFF position and #2 (final) position. Kill switch is set to RUN. Note, the bike only runs in the #1 (middle) position. Also, both coils are hot to touch in this position. Coils reading 4 ohms when tested/battery disconnected.
I've cleaned the hell out of the grounds. All wires related to the coils are in decent shape and well wrapped. Beyond re-wiring the whole bike, and buying a more modern ignition, I'm at a total loss. Any insight is greatly appreciated.

Last post by Vintagewannabe - October 12, 2026, 02:17:59 PMSo I guess this head has enough room in stock form to not be a compression/detonation problem?
The only other thing is I was told to torque at half value for the measurement.
For a bit of comfort and playing it safe I may run the thicker oe gaskets.
I got my 400 headgaskets from hvc, and they don't have the crimp/crush lip on them. They measure .5mm so they should be plenty thick

each motor is different, but i run tzr at .8-.85 mm for a data point.
