Hello, I've been having an issue with my 2013 honda fury. I just purchased mine about a month and a half ago and im having issues. When I start it up it idles low and then high then low then high ect. It does this until the bike powers off. Now I've changed the spark plugs, changed the engine oil, and I've changed the shaft oil. After doing this the bike is still having the same problem. I'm wondering if anyone here could give me a tip or insight as to what they think is going on.
