Only have 13! Let's all take a count..On a first road trip with my new F3s.. F3s vibrates bad over 55 mph. Think I found part of the problem besides the usual belt vibration. DAMN Kenda tires! 18, count emmm, 18 balance weights on the rear tire!!! Come on CanAm, surely you can do better than this on a new $28000 machine!!Really pissed! First stop is dealer.when I get home, if the tire doesn't fly apart first!

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
F3s tires! JUNK!

Like I said, I will ask the guys who know the mathematics. I am just the IT guy. One good thing about math is that it never lies. I'll let you know what they say.

REAR TIRE BALANCING
Neither of my last two rear tires were balanced at all......( no Kenda tires either ).....so far I haven't noticed any difference. I'm not so naïve to think both of those rear tires ( one Michelin and one General ) were perfectly balanced themselves.......Could it be they don't have to be balanced because they are on an axel that is supported / secured at both ends as opposed to the fronts which also involve steering sloppiness .......Any thoughts ? ? ?....Mike :thumbup:

In simple terms, if it rotates, then balance can be a factor.
The rear pulley operates at the same RPM as the rear wheel. The imbalance frequency is the same. The rear pulley should be considered light and the mass is closer to the center. This allows any imbalance to have less effect.
Real world may indicate to balance the pulley while on the wheel, but to be practical, it would be best to balance the pulley separately which will allow it to be installed in any position at a later date.
In regards to comparing front wheels supported on a hub to a rear wheel supported on a thru axle. The front can feel two imbalance forces. The inertia of hop and the inertia of wobble. The rear will normally only feel hop. However both should be balanced to a close tolerance.
For some crazy tool collecting reason, years ago I bought a used Snap On dynamic balancer. The small one that you spin by hand. I have not yet balanced the rear tire and have no plans to until it is replaced. We did have a left front that was vibrating the fender and could be felt. Balanced both fronts on my machine. Placed the weights along the edges, not down the center. Problem solved. Pretty certain it was off 1 oz.
Let the dealer or someone properly attempt to achieve a good balance. If it doesn't dial in with a few weights, then swap a tire or wheel.
Kenda does take flak about the tires, but BRP should take the flak about poor balancing.

More to fact every dealer has to use outside tire shops to do the work! Fronts seem to be ez rear hub is funny size & made my dealer have to make deals with 2 different shops. & all i can do is wait. Nice lounge area granted but waiting instead of riding sux!!

Do these tires have a preferred mounting orientation do we know. (Some companies have a yellow dot, or similar
so that the tire tech mounts on the rim in a certain place related to the tire stem....). Saves on the amount of
weights needed if you can turn the tire to balance first...then use the weights.

BRP obviously installs the cheapest tires they can buy on $30,000.00 spyders... Kenda's are substandard 2 ply tires... pure junk.. no other manufacturer uses tires that only last a few thousand miles... oh wait...I forgot... Nascar does...they change tires 4 to 5 times in a 400 mile race...& Goodyear drag slicks are worn out after 4 to 6 times down a 1000 ft track... Kendas do slightly better than that... ... :yikes:

I got 3177 miles on the bike, I take to the dealer for the common F3 vibration problem, and I'm told the rear tire is down to the wear bars! I hadn't thought to even look at the rear tire closely, it's only a month ago that I bought it! *******g cheap ass tires!

RideOn is applied by taking all of the air out of the tire, putting the goop into the tire via the valve stem, airing up the tire and then going for a 15-30 minute ride. in that time, the spin of the tire will spread the goop to all parts of the tire, but till it spreads evenly, it will be a rough ride. this also happens if the spyder with rideon sits for a while as the goop will settle in the tire, but in that case, within a mile, it's spread back out and smooth as a babys butt.
