Trying to dial in tune on fresh rebuild of 74 with stock bore. About 120mikes on build now. VM34 - PJ:25. MJ:180 Air screw only .5 turn but it already doesn’t really like choke; so I didn’t try 27.5 Pamco ignition and advance - timing looks good. Single coil. Idle ~ 1200 rpm New plugs, good battery, charging seems ok. This is all when bike is fully warm: Aside from the occasional ‘hiccup stall’.... I have one where when I come to a stop the idle drops very low. If I blip it, it’ll usually correct itself. If I don’t god chance it’ll stall. It’ll drop to about 800. So assuming one cylinder drops. now if I’m idling in driveway, I can’t recreate it. Only after riding down the road. I’m tempted to think it’s an electrical connection. But also still think it could be carb. They are synched, which was headache. I rerouted throttle cables to make sure they don’t pinch (I was thinking maybe that was case throwing out of synch but again I can’t recreate in driveway). No missing at speed either. I’m thinking possible needle position could affect but chopping throttle vs rolling out seem to have the same effect. many ideas on next step?
