In a previous post i mentioned that the green Dyna coils were a tight fit under the frame rails and i had to find a solution to this. There were other problems too:
One of the HT leads was always trying to work itself out of the coil due to the tight bend it had to make exiting the coil and miss the top frame tube.
I had already blown a fuse once due to the crazy design of the coils placing the LT terminals directly next to the (earthed) mounting post. I had got around this by insulating the terminals and post with insulation tape. i.e. a bodge
When i made the loom i had not fitted the coils, and when the coils were fitted the only place for the loom and its many bullet connectors connecting the main loom with the head loom was squashed in between the top frame rail and in between the coils. This then caused the main loom to be stretched and effectively too short straining all the connectors along its length and causing them to be pulled out when turning the bars
Schoolboy error again.
I also suspect that one of the coils is not operating correctly under load and causing the misfire that makes the flat spot in the carburation worse and harder to tune out.
Solution to all this was already sitting in my parts bin for the P&M:
New HT cables too. I like the look of the old style NGK plug caps. How they perform remains to be seen:
The loom is now a better fit around the battery area under the seat but still needs tidying:
I set the ignition system to test mode so that the coils continuously fire. At this point i noted that 2 of the plugs were not sparking across the electrodes but to the side wall - cracked porcelain insulators. So new plugs also went in.
Now starts first press (when the starter clutch allows) and runs much smoother. The huge flat spot just off idle is still there but i am sorting this out soon. There's salt on the roads now so its not going out for a while anyway, so i decided to pull the front end apart awaiting the new bottom yoke from Mikey:
