Backstory: I bought my 79 cx500c last fall from a guy who couldn't ride anymore (health issues) and he says he always stored it with stabil in the gas and ran the carbs dry. When I test drove it, it had all the power and no spits and sputtering or anything. I brought it home and ran multiple tanks of gas through it, probably 5 or 6, and then one day it just bogs when I give it hard throttle in any gear above 3500-4000 rpm. I pulled the carbs and did a quick look at the bowls and jets, jets were basically clear, little sediment in the bowl. When it bogs, pulling the choke does not help, and the bike always starts super easy and idles with no issue. Runs great if I'm light on the throttle, it is still completely rideable, just takes a while to get to speed because of the bog when I punch it. I have done the stator test when it was both cold and warm, plugs look like fairly new ngks. The bike only has 16,000 miles, not sure if that's enough to cause the stator to go bad or not. Just looking for some input on where to go from here.
