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.

A failure rate of .001% is a big nothing burger on a great machine
I had "red dust" and found it prior to failure because of this thread.
Even with that stated I still think this issue is a big nothing burger.
There is no citation on how many bikes suffer(ed) from this issue.
We can "guess" it at a few hundred bikes but that is still way under 1%.
Of that few hundred "red dusted" bikes maybe a few had epic failure on the road requiring a tow.(making it 001%?)
My point....I don't want someone thinking the bike has a fatal flaw and not understand were the decimal point is located.
BTW...Can Am REPLACED my red dusted front sprocket and it was a stress free ordeal.
The riding season is kicking in and I plan on doing another 20,000 miles this year and not gonna worry about "red dust".

This all boils down to one thing;
Check your front sprocket at the beginning of the season and at every oil change. More often if you feel the need to do so. If red rust is there, contact the dealer.

Has anyone here actually changed out one of the pulleys themselves? Mine has a bit of red dust on it but out of warranty. Decided to just change it out rather than wait for it to fail. I removed the bolt, removed the belt but darned if I could get the pulley off. It seems to be rusted in place. I tried a pulley puller but there is not much room around the edge of the pulley and did not want to damage it beyond use. There are no threaded holes in the face of the pulley so a jaw type puller was all I could think of. It refused to come loose. I gave up, installed and torqued a new bolt and washer.
How does one remove this pulley, there is nothing in the service manual as its not a press fit, its supposed to come off pretty easily. Do I just wait for the rust to progress and the splines to fail then it will come off when loose?
I have spoken to a few Spyder techs I know and most come off without too much persuasion. Some do not and things can get 'bad' Seems there may be more wrong with the design than just the lack of proper lubrication on the splines.

i suspect you read the info and saw the photos I posted on Facebook a while back. On our 2014 the front pulley was lubricated at first assembly. No red dust, no wear and easily slid off with hand pressure.
Fretting corrosion is an unpredictable event. Obviously you had the drive belt removed, and with that the pulley is a slip fit.
My suggestion would be to add oil to the splines with the bolt and washer removed. Fire the engine and roll forward and aft, working the lube into the now excessive clearance of the splined joint.
In theory, the pulley slides off easily, however worn splines may snag that. It could also require additional rotating back and forth as you draw the pulley off the shaft.

Does this look okay to you guys?
Just looks like surface rust to me.. No sign of martian dust..
I think you are right. Usually will fill in the holes.
This was sent me a couple days ago by a ryder. He is getting it replaced.
This is my sprocket after 10,500 miles. Guess it's time to call my original dealer, since the closer one in Stamford, CT never heard of this problem. I'll have them install a new belt that I got from Amazon, since they were telling me that mine was shot the last time I was there. Any suggestions on how to handle them if they put up a stink?

Yep, yours got bit. I wouldn't tell them where you got the belt (has to be a BRP one anyway). I would just tell them you have a spare belt and would like it put on. Also, you might get them to warranty the belt. Ryder on FB just had his sprocket done and the dealer did the belt also.
Is there a service bulletin # that I could quote, since this is the first they are hearing of it as well?
Anybody have a # for the BRP service bulletin on the sprocket?

Hi,
You may visit our website and enter your VIN to see if your unit has any safety bulletin.

As of a couple weeks ago, BRP still has not published a service bulletin on this problem. They are however, quickly and easily approving the replacements. If the pulley exhibits the red oxide dust, they authorize replacement as failure is approaching.
I do recommend re installation involve moly lube on the new sprocket splines as is industry practice. Installing dry is a known failure method for splines that are not press fit.
I'll be going to the dealer on Wednesday, so hopefully they will then order the required parts. I'll bring a print out your response if they need a bit of a prod to contact BRP!
Thanks!

Anybody with the red rust has not be denied to my knowledge. If they give you a hassle, make sure and report them to BRP. Information flow back to them is the best way for us to get the best possible service work done. I have sneaking suspicion that they will be really monitoring how their dealers are treating their customers even more so from here on in.

Just so you know, that dealer no longer sells Spyders, new or used. There are a lot of things they never heard of. Go somewhere else. I go to Arctic Adventures, a long way from me, but trustworthy, upright folks, and worth the trip.

Arctic Adventures? That DOES sound like like a long trip, oldguy
Do you need an Inuit guide to get there? Pete

Nah, I just follow other Spyders from this area that are headed there.
hyea: 87 miles isn't too bad, except for having the ride the Interstate & New York Thruway.Thanks for the heads up. They suggested that I bring it in for a look, so I definitely won't!
The mechanic told me that BRP would not authorize the work, but I found out that my warranty was not still in effect which was a surprise to me since I thought it was.. Well, one thing leads to another, as I will get in touch with BRP next! Wish me luck, as I will probably have the sprocket replaced regardless of the warranty question!
