• 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.

Roller upgrade for Doc Humphries Vibration Damper

No Spyder comes with a drive belt dampener. There are so many variables with this issue. Some people don't really care if their belt vibrates. It drives others crazy. Some vibrate a little. Some vibrate a lot. For some, the vibration resides at a speed that they run all of the time. Others get vibration at a speed that they just motor through on the way to their usually speed.

Some have adjusted belt tension and gotten good results. Others never seem to be able to get vibration reduced to their satisfaction. It's easier to install a dampener than to trial-and-error belt tension hoping to get lucky.

So, it really depends. It's not a 'One solution fits all' situation. The real issue here is why so many dampeners fail. And when they do they usually take your $300.00+ (parts only, installation not included) drive belt with it. The dampeners work great at reducing or eliminating vibration, for the most part. Getting a reliable one has been somewhat of an issue. With the BRP offering being, by far, the worst of the bunch, it seems.

My 2019 F3-S came with BRP dampener OEM. Upgraded to Lamonster roller shortly thereafter.

Really! Are you sure it wasn't something the dealership installed? I was not aware that any Spyder left the factory with a drive belt dampener.

(I have sense learned that some Spyder did, indeed, come with the drive belt vibration dampener installed from the factory)

It was on there, and I didn't pay any extra for it. Brand new out of the crate. My 2019 F3-S also came with the SS style grill too..

Could be the dealer put it on for his own reasons. He may have had belt vibration issues with past owners and figured this would be a way to avoid them in the future.:dontknow:
 
I received my new belt tensioner from Lamonster yesterday . I check it and it does have the 6202 RS bearings. If I understand it these bearings are good for 12000 RPM. I don't ride that hard. Very seldom ride over 80 mile an hour. Interstate 70 to 75 mph.
 
smooth spyder roller

in reading all these posts, has anyone had any problems with the smooth spyder roller, or have any knowledge of such?

Same here, my girlfriend and I purchased new 2018 F3T’s from separate dealers and they both came with the BRP tensioner. I thought BRP had the tension issue resolved when I test drove them. I was performing some mods later on and to my surprise discovered the tensioners on each Spyder. I contacted the dealers and they didn’t install them, so it appears they came from the factory that way. I replaced the rollers right away with the Lamonster roller.

I guess starting in 2018 BRP installed the tensioner on the Spyders with the 89 tooth rear sprocket which would be the F3T and F3S. The only Spyder for year 2019 that has the 89 tooth rear sprocket is the F3S. I’m not sure on the 2020 F3 models.

OK. I was not aware of this. I stand corrected! You learn something every day (if you're paying attention).
 
The long and short of this whole post is that, just like having to change your oil, if you have one of these units on your bike you should defiantly be checking it at the same time for wear! It has bearings and spins like hell down there, and bearings do not last for ever, no matter who's unit you have. Myself, when you roll down the road you can feel every thing on the road, a little vibration for the belt I think I can live with so far! Now if it vibrated as bad as my fathers old electo glides use to, right up threw the foot pegs, I would have a problem with that!!:2thumbs: Good Luck guy's, and gal's with your dampeners!
 
Looks like upgraded bearings will be a 10k mile maintenance item. Didn't really look, are their two sets of bearings in the Lamonster roller?

I'm pretty sure it is a 2 bearing set-up same as Doc's, just 2 different RPM rated bearings.

Had one on the 2013RT I had. It was still in good shape when I sold it at something like 20k to 25k. The last time I looked the one on my 2014 RTS was rolling good at over 32,000 miles.
 
I took my damaged Doc blue roller apart today to examine the bearings inside. I removed the metal side shields and can understand why these fail.
all of the grease inside is dark and dried out. There are no numbers anywhere on this bearing

HANG ON Everybody! We have a bearing issue concerning the called out SKF 23Y196 https://www.grainger.com/product/SKF-Radial-Ball-Bearing-23Y196

Just picked up the above bearings this morning and got another Lamonster roller this afternoon. the issue is that the above bearing has a 15mm bore and the new Lamonster roller bearing has a 5/8 bore.

The other issue, So looking at the stuff included with the Lamonster roller and parts from Docs set up, I think we are looking at a couple bucks at the hardware store to convert with no drilling the arm.

Are you saying there is a problem with the new bearing in Lamonster's latest tensioner? If so I am removing mine and forget a tensioner.

Keep it stupid, simple! How many miles did you ride with out one and did you really have a bad vibration or was you just keeping up with the jones? Possibly just a belt adjustment could make your ride as smooth as you have it now, and it would break down when you don't expect it! There's no problem with any of them, you just have to check them to see if they need to be changed out!!!! Bearings do not last for ever, they have to be checked! Think about every thing that little wheel down there go's threw and what it's doing! If I had one on my bike it would be checked as much as the oil!
