Just picked up the bike yesterday and when I test rode it, it ran fine. I get it home and I think it started running on one cylinder. It only does this after its been running for a while. I wasn't sure this it the problem because when I get on it hard the thing goes like crazy. So it must be hitting on both cylinders at wide open throttle. But when idling I'm sure it's only hitting on one. Any one have similar problems? What should I be checking for? Please give me a hand with this. Thanks in advance!!
