Hi all, I'm pulled over on the side of the road on my new to me r50/5 with a retrofitted 75/6 motor in it and dyna111 electronic ignition. I've ridden 30 miles and decided to pull over and check out the sights.. I'm stopped about 30 mins and start going again except she starts to stumble thru the revs. I pull over shut her off. Star her up and stumbling is gone... start riding everything is perfect until 4000 rpm where she then stumbles and the alternator light starts flickering.. I pull over rev her to 4000 and stumble and flicker. Above 4000 and it goes away... wtf? Carbs were completely rebuilt 100 miles ago. New spark plug wires, battery, 4 gauge battery cables... ground connect cleaned and paint scraped off frame... this just started today... any ideas?
