Re: R69 no spark
This is where I got confused- when the"v" mark is in line with the line on the rotor, it aligns with a red painted dot on the flywheel, viewed through the inspection hole, not where the"S" mark is on the flywheel. If I move the flywheel so the "S" mark is dead centre of the inspection hole the line on the rotor is way to the right of the "v" mark. Which is the correct way?schrader7032 wrote: ↑Sat May 14, 2022 5:42 pmWas the magneto aligned properly? If it wasn't, then it's possible there wouldn't enough energy to create a spark.

Re: R69 no spark
As I think about this, though, I'm not sure a misaligned magneto rotor would cause a no spark situation. The magneto needs to be aligned so that when the magneto outputs the maximum spark energy, the engine is near the S-mark. The magneto spark is actually pretty weak at slow RPMs such as kicking speed, so this timing needs to be the best in order to get the bike started. If the magneto were aligned somewhere else, seems like it would still spark but just at the wrong time.
