i got a 2006 hammer that only gets 25 mpg and has engine vibration
had the map reset by dealer did not make a difference
any body got any idea whats wrong?

Pmatts,
I wish I had an answer but something doesn't sound right for sure. Did the dealer try the bike out after they remapped it? They didn't have any ideas?

I am not a mechanic but I had similar problems on a Honda years ago and the guy I took it to , did some routine maintenance on it (changing filters, plugs, wires etc) and this made a huge difference in fuels consumption. I would definitely get it looked at. I am thinking that the vibrations are contributing to your poor mileage.

have the same problem with 2006 hammer,at 2500rpm get a vibration moving or not dealer said all is ok.it was not there a year ago. i to am looking for help !!!!!:confused:

How many miles on your bike?

These bikes are not perfectly counter balanced. Some imbalance was left in to give the motor some "feel". Not sure how much vibration you have, but a little is normal.
As to milage; the first thing needed to be done is a throttle body cleaning. If it still persists then the TPS adjustment needs to be looked at

the bike has 8800 miles.

Did you try putting a little bit of seafoam in it?

yes , i have

One of my friends has a 2008 hammer that was shaking real bad. He tried everything and the dealer showed him how to strap it. He took a winch strap like you tie motorcycles down with and ran it over the back jug and under the bottom of the frame than winched it real tight. Worked like a charm and it doesnt look that bad. Actually it looks pretty cool kinda like those straps you see on dragster engines. If it gets loose and starts to vibrate he just gives it a click.

Have you done what Kevin said about cleaning the throttle bodies and if you have did you take it to the dealer for a TPS adjustment?

FYI Kevin is a mechanic at a Vic dealer and considered to be one of the foremost authorities on our bikes.

Hey Kevin....Can you set the TPS on these up with a digi multimeter or do you have to have the Digi wrench?
