Your right, just got back from an elk hunt and dusted my engine badly but it seems to be running ok now that things are cleaned up. First indication was it quit wanting to run at idle. If I would have stayed home one more day I could have read the reply from the list of issues I have had. I changed plugs and oil and cleaned the intake system. I had a K&N filter with me but pulled it off because it got plugged up and I didnt have the oil with me. thought the stock cleaner was good enough for a backup. Thanks, Thin Air Powersports, for the help and parts.
