My ride when I’m going full throttle at about 4500, 5000 RPM it starts to cut out and sputter and bog down, the only thing I have done to it sense the last ride when it wasn’t doing that was pull out the air filter to clean it. It is not a stock air cleaner it’s the cyclone from dragonfire. it has also after market exhaust and a fuel management system, normal trail riding doesn’t seem be a problem, I just don’t want to be in the back country and the thing take a dump on me..
