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.
Has There been a FIX for the 15/16 F3 Front Sprocket?

Here is one example; there are others.https://www.spyderlovers.com/forums/showthread.php?132041-F3s-front-drive-belt-sprocket

I have not heard of a fix, as BRP hasn't really confessed that there is a problem. I check mine about every 4-6 months, and before long rides. Most manufacturers will not own up to an issue unless there is a danger to the operator, and then they will do a recall. As of now, it is just a random event that occurs and they seem to fix it when it happens. Now I am not sure what they are doing once a bike is not under warranty anymore. That is the question that I would like for someone to comment on.

Its not limited to 2015 and 16 F3. Its a problem with ALL 1330 equipped Spyders. They ALL are using the same sprocket part, even the brand new 2020RT is using the same part. BRP has not acknowledged this is a defect nor have they really fixed it other than lubricating the splines on sprocket install now.

Can Am said they fixed problem by using a diferent metal what ever that means. Rust dust stll indicates sprocket metal is same now as before. Strange sprocets still creating rust dust in 2020 F3 & RT's. My 2016 F3 sprocket splines were completely "rusted' away, gone. I just barley made it to dealership befor sprocket splines stripped. Back then there was quite a bit of talk by experienced Spyder technicians, mechanics and engineers opined problem was a simple design problem. Spcket and drive shaft mating surfaces were too small and sprockret bolt was also too small. There were sugestions to increase size of mating surfaces and a larger sprocket bolt. I'm a mecanicl engineer and that made good sence to me. Drive shaft Splines have been used in many vehicles and and lasted 100's of thousands driven miles without failure.

BRP has never admitted to this being a problem so no fix. There are too many reports of front drive sprocket failure mostly F3 & RT spyders 2014 - 2021. My 2016 F3 sprocket failed at 8K miles. As an engineer I have give much thought to how this on going problem can easily be corrected two ways: one expensive but IMO an end to all future problems. Second fix less expensive may again only be temporary but drive sprockets should last much longer, no rust dust.
1. Go to a tapered spline drive shaft and belt drive sprocket with chrome hardened spline and larger bolt.
2. A front belt drive sprocket with chrome hardened spline. No more rust and much longer reliable life. Current drive sprocket spline softer metal designed to wear out before drive shaft spline and easier to replace than a more expensive drive shaft replacement.

After reading about so many failures, I ordered some "assembly paste" just in case. Next time I go to dealer I will get/order a bolt. Looked at the sprocket the other day and it showed no rust at all. I didn't put the torque wrench on it, thinking that to do so would break the original loktite.
Am wondering though, should I replace the bolt since the torque value has been increased from 80 to 110?

I check my sprocket every 2-3 months, or before any longer trips. I also have it checked by the dealership when taking it in for service (oil change). So far, I have right at 23k miles and no rust. The way I see it, if it ain't broken, I ain't messing with it. But that is just me.
