Mine is doing the same thing again. My warranty is up so I ordered the evolution tune. Should be coming soon.Seems like it fixes the problem according to the 505 outsiders YouTube couple.These things run too rich from the factory. I am also switching back to non-ethanol after the tune. Brother-in-law got the HD-11 and hasn’t had a single issue.
