Every morning my bike starts and runs great. I'll ride it 23 miles to work with no problems. When I ride it home, the bike seems like I have a v twin instead of a v4. If I stop, turn it off and let it set, it may run like it did in the morning. There's no consistency to this other than no problem when first started for the day. Same thing happens if I start out on a ride in the am and have to stop for gas. Runs good before the stop then back to what feels like a solid mount Harley engine. Any ideas?
