Just took my new to me 2015 F3 for my first real ride. Around town it's great but got on the freeway and at 55 or so the front end starting vibrating and at 65-70 it's pretty severe The tires are new but I see only the old sticky backing and no weights,,TIRE BALANCE?? or Front Shocks..the bike has 29k miles...
Kind of hard to trouble-shoot without knowing more, but most likely the wheel balancing. That's the place to start. Or, take it back to the dealer you bought it from.Quote:

As previously stated it is most likely a tire balance problem at those types of speeds. It would be shocks primarily if hitting a bump were to trigger the vibs. My wingman has an F3 with the stock front shocks at 29k and has no problems! But what is more likely is if it has the Kenda's on it they are known for many issues including not being able to get them to run smoothly even after balancing.Quote:

I am using the Federal Formoza AZ01's on my F3-S and replaced the Kenda's at only 4500 miles due to lack of performance and vibration! And if you don't like looking at wheel weights like me, look into Lamonster Garage's Centramatic Wheel Balancers. They are a dynamic bead-in-fluid balancer that is mounted behind the wheel. They rock! Enjoy!
They are Kenda's and I'd bet the dealer put them on. They are brand new and I'm betting they were put on when traded in..not being balanced when installed...not surprised a bit..the less I deal with the dealer the better..
All my vibs went away with a pair of Federal Formoza AZ01's AND the Lamonster front Centramatics, Spyder's so smooth an open glass in my handlebar cupholder doesn't slosh.....
Just talked to the dealer service and they put something in the tires for dynamic balance?? Going to have them balanced Monday.. as I said I don't like dealers..
Where did you get the Lamonster front Centramatics from, how much and the part number??
So these are brand new tires you just had installed at the dealer. This fills in a lot of missing information.Quote:

Most internal and external balancing products will only compensate for a certain amount of 'Out of Balance' condition. Not to mention, it is very possible with Kenda tires that they are not round or have suffered cord separation. If so, it is not possible to balance them no matter what you do.
If you jack up the front of your Spyder and spin the tires. You can usually tell if you have an 'Out of Round' or cord separation issue. You might consider putting some decent tires on instead of the Kendas regardless of why you are having issues with balance.
Good luck and let us know how this turns out.

It is fair so say that if you get a poorly made Kenda, it is VERY poorly made.Quote:

You can then decide whether you want to go with weight balancing or the Centramatics if there is still some vibration.

Unless you requested they put that crap in there, they had no business doing it. Have them remove your tires and clean that **** out AT THEIR EXPENSE! This is what happens when ATV mechanics are expected to work on sophisticated motorcycles.nojokeQuote:

I just ordered a couple federal famoza from carid..get them mounted locally..
Please keep posting updates, Sticker. This is valuable info (albeit at a significant cost to you, but hey.....I’m not worried ):DQuote:

Good luck!
I rec'd the tires and had them installed. The shop could not balance but they did mount them with the balance dot to the stem. His balancer didn't have the proper spacers but he thought they were close... damned if he wasn't dead on!! No vibration at all up to 75. I will look into the Lamonster set up but I threw the Kenda's in the trash. The dealer had put some sort of dry balance but that would not have fixed the out of round issue. Thanks to all for the advice..
I reported here a couple of months ago that I DIDN"T spin or do other balance for my 8 wheels I recently mounted with new tires. I did what your shop did and just put the Red dot at the valve ..... smooth as silk ....... Mike :thumbup:Quote:

First, guarantee that it's from the tires. Maybe you need an idler arm to stabilize the belt. The speeds you describe are commensurate with a vibrating belt. Just tossing out ideas.
