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.
Any ideas on this 2012 Spyder RT knocking sound?

It sounds like the clutch is chattering while trying to engage. I think this is somewhat common on the older RT’s when the oil is cold. If my memory is correct, BRP produced some different clutch plates to help with the chatter. But if you let it warm up a few minutes before riding off, I think you’ll greatly reduce or eliminate the chatter. A fresh oil change may not hurt either - if it’s been a while. You may also want to be sure the front pulley is tight and without any “red dust” indicating worn or damaged splines. It looks like your display went blank when starting - may want to load test the battery too!

I agree. They chatter when cold. If it does it warm, CHECK THAT FRONT PULLEY!
Not sure that the pulley will be an issue on a 2012 - up until 2014 &/or the advent of the 1330 Triple motors, the V-Twins had a harmonic balancer type 'add-on' fitted to that pulley, and I don't believe there's been too many if any red dust issues reported on the pre-2014/V-twin models - at least not here that I can recall?! :dontknow:
But, as others have said, I too reckon that's the noise most pre-2014/V-Twins make as the clutch tries to engage when the oil is cold.... it occurs like that & is most evident/just like that on my 2013 RT (that came with the upgraded clutch plates) when the oil is cold. The remedy is, again as mentioned, to simply let it run long enough to let your oil (& not just the coolant
) start to warm up a little, and that noise will be significantly reduced/minimised... 
hyea:
Btw, I believe the upgraded clutch plates weren't intended to minimise or reduce that noise per se, they were more aimed at making sure the chattering, which is basically unavoidable to some degree with this type of clutch, wouldn't cause or result in any damage. :thumbup:
So all up, like everyone else here, I reckon that noise is 'normal'; it can be minimised by letting the oil warm up a bit more; and just like the 'clunk' that most of us get on first engaging a gear after initial start up, it isn't likely that it's gonna be hurting anything. :yes:

I’ll check this out tomorrow but I am pretty sure that the clanging or banging happened the other day after it was already warmed up.
We bought this thing last year and rode it all summer without any problems at all.
It only has about 7500 miles on it and we put maybe 1500 of those miles on it.
It’s been running like crap and stalling and then this banging started on Saturday.

I should also point out that I did the “canister-ectomy” the other day before I posted that video after reading about how it could solve the rough running problems.
It didn’t get any better.

Maybe there's something else wrong with the clutch?? :dontknow:
It might be worth finding your VIN & checking with a dealer to see if that Spyder ever had the 'clutch plate upgrade' that came out around late 2012/early 2013?? Sorry, but I can't help with any of the numbers for that... Just a thoughty tho...
I called the dealer today about taking it in, they told me they are about 2 weeks behind before they can get to it.
Pisses me off that there is a closer dealer to me, like 2 miles away but when I called them and told them that I had a 2012, the guys says we don’t work on Spyders that are that old.
I would really love to not even use a dealer but I am not that sure of myself to work on this thing in case it’s a big job.

Maybe you'll get a better response if you just ask them to run the VIN so you can see what's been done to it over the years?? :dontknow:
I have not replaced any vacuum hoses since we have had it.

I have a 2012 RTS and have never had this knocking sound, just that one clunk when putting it into gear from neutral !
It is important that you have the proper oil like Pirateez also mention.

Upon initial acceleration it will knock from underneath and appear to have a loss of power. I’ve recently did a complete oil change, changed the fuel filter, put a new battery in, did a test on the purge valve and yet it continues to do it to the point it’s unridable. The only thing I’ve done different to the bike recently is put a Voodoo exhaust on however a buddy put the same exhaust on his 2010 with no issues.

Well, if it sounds anything like that video does - which is a heart rending sound - I think that it's either internal to your clutch, as the centrifugal clutch starts to engage the clutch pack, or it's a front pulley issue. That cold oil issue wasn't anywhere close to that problem. Pull off that left side panel so you can get a clear view of your front pulley and associated bolt as you put it into gear and try to pull away. You'll probably need a friend to help. Preferable a mechanically minded friend. Or you might find something wrong just by looking at it. Whatever it is, it's more than just cold oil.
You might also try sending a PM to RazorV. But his last post on the forum was the one above from last May.

What oil did you use?
Have you looked at your front pulley?
What happens when you attempt to ride it? Once you get moving, does the sound go away, even under hard acceleration?
The 2 most likely causes are, as mentioned, clutch issues or front pulley issues. Having just changed oil could certainly be an issue with the oil used.

If the sound is only associated with acceleration, particularly hard acceleration, and isn't quite so metallic sounding as that in the video, then there's a chance that it might be associated with worn pulley teeth or possibly more likely, worn teeth on the belt?! :dontknow:
I ran into one of those ^^ just recently; a harsh and rapid 'knocking' noise associated with acceleration that became much worse under hard acceleration and was always accompanied by an apparent loss of power.... :shocked: Only it wasn't strictly a 'loss of power' so much as a 'loss of DRIVE'!! The rider of this 2014 RT SE6 freely admits that he flogs his bike and rides it hard ALL the time, has done for the last 160,000 odd km's without any concerns; but then this noise started up recently under hard acceleration and has become progressively worse over the last 5,000 or so kms; so much so that now any revs over about 3500 will bring it on, and it rapidly gets worse from there as the revs go up and the drive drops off! :yikes: It was quite difficult to ride it without bringing it on...
Upon inspection, the belt looked to be in good condition from above, but upon twisting it (to do a rough test of tension) it was suddenly very obvious that it was waaayyy worn :shocked: So much so that the teeth didn't look like 'half-round' protrusions on the inside of the belt, but rather they looked more like '1/4 round' protrusions with a sharply angled concave face scalloped out of the pulling quadrant!! _/D_ is the closest I can get here, only the / was more hollowed out! The belt wasn't massively loose (still no Kricket that clicks here, but it only twisted about 100-110 degrees, so it's only a little looser than a belt that twists the usually expected 90°) and neither of the sprockets have teeth that look obviously worn, unlike the last one sounding like this that I saw! :yikes:
All of this ^^ was resolved with a new belt and an admonition to play a bit gentler with his toys! I believe he's happily done another 5000+ kms since :thumbup: But I doubt that he's really treating it any gentler!
That other one sounding sorta like this that I mentioned had a loose/worn belt AND a clutch/output shaft issue - I discussed it here: https://www.spyderlovers.com/forums...-revs-under-load-Any-thoughts-on-cause-remedy
Anyhow, no idea if any of this helps at all; just putting it out there as another possibility and maybe some food for thought?! :dontknow:
Over to you - Good Luck! :cheers:
