Rear fairing for top trunk removal on 2019 F3-L

[Longlegs]

Put balance beads in the tires.

So...I bought this bike from Pitbull. They balanced the wheels 3 times and could not get the front end to not shake. Head Motors balanced them stating 3.5 total ounces were off both wheels combined. Even after they balanced them, the shake is still there. I will not use aftermarket parts or inner tire methods to fix this brand new custom bike. This should not be happening. I'll share later what fixes this mess. I am currently trying to find anyone in Missouri (or further) who has a Road Force wheel balancing machine who ALSO has the parts to fit this wheel in the machine. So far, no tire place or car dealership has those parts for this size wheel, even though they have the machine. Before I knew the vibrations / shaking of the front end even existed, I added to my bike order a belt tensioner, sway bar, links, King Shocks and of course new tires all to ensure the smoothest possible ryde.

Anyway, to the credit of the OP and my apologies for high-jacking...I made a video to share with anyone intersted on how to raise the top case on a 2021 F3 Ltd. So far, it's been a PITA to figure out how to remove the top case. I have only gotten as far as raising it...removing requires a few other items.

If your dealer is still being pro-active with regard to getting this vibration issue sorted, just ask if they have another Spyder that DOESN'T have the same vibration that you/they could temporarily swap both wheels with in order to see if the vibration follows the wheels that're currently on your Spyder?!? :dontknow:

If you exchange a set of front wheels with a Spyder that doesn't have that vibration & test ride the exchanged wheels on both machines to find out if the vibration follow the wheels or stays with your Spyder, it could really narrow down where to look for the particular vibration causing issue! :lecturef_smilie: Amongst other things, there's been more than one Spyder that left the factory with 'out of round' front RIMS; probably more that which've developed that problem after bouncing off a kerb or hitting a big pothole on the road; some that've had hub alignment issues &/or spindles that weren't 'straight' (either from the factory &/or as a result of road damage) so the wheel could never track truely; early failures in ball joints &/or other suspension components; issues with the DPS; & instances where BUDS was needed to re-set 'straight ahead' in order to stop the DPS from fighting with the rider to keep the machine heading straight down the road; and more, even without even going into the potential for rear wheel balance & alignment issues; or belt vibrations etc being the cause of your vibrations....

So there's a heap of things that MIGHT be causing this vibration you're getting that aren't necessarily related directly to the front wheel balance, especially since you tell us they've tried 2 different sets of new tires already.... Altho if both sets were OE spec Kendas, then that doesn't necessarily exclude them from being the cause, as it certainly wouldn't be the first time that someone lucked out & got more than one set of dodgy Kenda tires! :gaah:

Anyhow, swapping the rim/tire assemblies with another machine that DOESN'T have the same vibration might just help you/the dealer narrow down where to keep looking for a cause. If you can swing it, then it's worth a shot, surely?! :dontknow:

Hey Peter...I will talk to the service manager at Head and see if they will swap wheels as you mentioned...good idea btw. In the meantime, a local fellow Spyder ryder / friend said he'd be willing to swap wheels to checkif Head cannot. I have read as well where someone had gone through 3 sets of tires before the last set worked. And, I agree...it is possible the issue is not the wheel balance...already spent a small fortune, might as well keep going until I run out of options. As of now, I have parked it...might ride local, but over 55mph it's no longer enjoyable.
