Synced the carbs and checked the PMA today. Bike runs beautifully now, idles nicely, revs cleanly, no spitting or hesitation. PMA/reg/rect output is 14.6 volts, so happy with that as well. Timing is spot on on both cylinders, so the single points cam also works well and the filter and cooler deliver a good oil supply with no leaks. Fancy that, all the engine mods worked as planned! This is my homemade manometer I use for syncing, super easy to use, gives a good, stable reading.
