Only happened once (so far). I always use premium fuel, plug into a Battery Tender if the bike sits for more than 1 week and it's kept in a garage. Had not been started for 10 or so days. Went out to go to work yesterday and turned the trike on, started gearing up while waiting to start it. When I hit the MODE button and then the starter, it started chugging but did not fire. I held the starter for about 10 seconds with no fire. Waited about 30 seconds and tried again but this time I gave the throttle about 1/2 twist and it started to fire and eventually did start, HOWEVER, it ran rough until I got on the road and got about 200 feet from the driveway. It ran fine for the 51 mile trek to work. I work second shift and would be riding home at 1:00 AM. It started fine and was again normal, BUT, has me worried. Any ideas?!?
