I just brought mine in 2 weekends ago for a problem I couldn't resolve. I should've seen it, but I didn't so I brought it to the dealer. They suspected a vacuum leak and replaced some rubber bits and pulled and cleaned the spark plugs I had just put in. They called and said my bike was ready. When I got there, I will admit the bike did stay running, which was better than when I brought it, but it still ran like crap. They actually asked me if this was the normal way it runs because I would know my bike better than them ?!?!?! I look over at a new Rocket, and then my Rocket, and said well no.. it was running as good as that new one. They said this was as good as they could get it.. $480.. for the 5 hours of labor..
I brought it home.. looked it over good again.. and found 3 cracked spark plug wires! Both plug wires on the rear cylinder were completely exposed firing everywhere but the plug.. and one on the front cylinder.. Now, yes I should have seen this before.. but when they pulled the plugs to clean them, it was pretty obvious.. Ordered the plug wires from BikeBandit last week..
Last time I took it in, I paid them to $140.00 to ride my bike. It had a high idle problem.. They said they couldn't duplicate it.. I started it right there in their parking lot idling at 2,000 RPM. They offered to look at it again and I said I would figure it out.. Turned out to be the idle stepper motor.. I just backed it off to 800 RPM and have had no issues with that ever since..
Sorry I'm not instilling confidence in your dealer, but I would feel bad not telling you as well. The Rocket is a great bike.. and I sure am going through withdrawals!
