Issues, and I ain't happy
Issues, and I ain't happy
My 2011 Street Bob has done just over 2k miles and yesterday I went out for a 200mile trip for a meet up. Anyway as soon as I got on the Motorway (highway) I could feel the motor seem more vibey than before particularly coming through the right hand side foot rest and hand grip. The motor is running it's usual sweet running self and there are no untoward engine noises, but the vibes made my right hand and foot tingle for several hours afterwards. It ain't pleasant.
I've also noticed the spark plug on the rear cylinder is a slightly lighter colour than the front cylinder. This surprised me coz I thought if there was any bias in fuel ratio between the cylinders, I thought it would in favour of the rear cylinder because it runs hotter due to less air flow.
I will be contacting my dealer, but I would appreciate your thoughts on the matter......or am I over reacting?

Any particular speed/RPM causing this vibration...or was it happening entire duration of ride? Lace wheels can have loose spokes, or steering head/wheel bearing might be acting up & could've thrown a weight. Hard to say, but have dealer check it out w/warranty coverage...good luck!

Ditto the above
My bike went into my local Harley dealer Last Saturday, I also gave them the print out re the Harley service bulletin on excessive Dyna vibration....
They didn't appear to know about the service bulletin......
Hopefully should be sorted and I'll be able to pick it up this week end.
