Feel free to scare the crap out of me as this evening I kicked the bike over twice with the plug in the endcap. I was attempting to start the bike to warm up the oil for a routine change and after the 2nd kick I did a Chris Farley cartwheel off the bike as I forgot the plug was in it!!!!!! Took it for a quick spin after warmup in my field and road, seems fine. Whats the worst that can happen from doing such a thing? What should I check for damage? Maybe cause an air leak in the exhaust system? Thanks in advance..
