I've never had a problem. Make sure there aren't any dangly bits hanging down by the belt, and no debris that can get into the intakes. I remove the switch from the cowling so I don't have such a big chunk of plastic in the way.Any issue starting 2012 apex xtx immediately after replacing the battery without putting the air box, headlight, dash, etc back together? I am thinking I can just plug the ignition switch back in and start it, is there anything else I should plug in as to not do any damage?
