i just changed all 3 oils in my 2004 dyna superglide and now it seems to have a vibration ... i see it most at about 45mph in 5th gear.. it also does it sitting still at a hair above an idle.it shakes the whole front end.. it might just be me , but it seems to shake more... oh and i changed to klotz syn... don't know if that would have anything to do with it tho... thanks ahead for any help...

As long as you have used the correct grades of fluids, and your levels are correct, there is no reason that there should be a vibration as a result of the fluid change.

45 MPH is 5th gear is probably very near lugging the engine, and that could be causing the vibration at that speed.

The rubber mounted engine on the Dynas tend to shake quite a bit a idle. The handlebars, engine, and everything shakes at idle and just off idle.

How is the bike at highway speed?

the bike is fine at highway speeds , but even when i'm slowing down and it hits around 45mph it shakes a little until it drops to about 40mph and ... it might just be me.. it just seems to shake a little more than i thought it did before... thanks for the response...

Sounds about normal. I know, I know...this is what a dealer would probably say, but I have a Dyna and it seems to do the same thing. 45 mph in 5th gear is lugging the engine. Twin cams like to be above 2000 rpm. If it falls below 2000 rpm, its time to downshift. I try and always keep mine between 2500-2800 rpm, the sweet spot so I'm told.

 

did you check to see if the exhaust is touching something?

 

Almost forgot, be sure to check the upper motor mounts. Mine came loose and caused an awful vibration.

 

I'd check to see if everything is tight

 

Those oil klotz will shake you to death..[sm=itsok.gif][sm=joke.gif]

 

Do you think maybe its possible your front rim is out of balance since that would create the problem you are stating.

I'd put the vibes down to just one of those things that a bike with 'character' has, something these babies have in spades. I wouldn't lose any sleep over it.

If I ride my Dyna Sport at 45mph in top gear, the motor feels like it's trying to leap out of the frame, the revs are waaaaay too low for comfort. On starting the cold motor, the Fi makes the engine idle at approx 1200rpm, making the front end shake noticably - once warm (where the idle's 1000rpm or so) the thing's more settled.
