• 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.

Which is the best Belt Tensioner for an F3 LTD?

Got a new F3 Limited a few days ago and found it to have a lot of vibration at highway speeds. I was looking on here and found basically 2 different styles, one applies tension to the upper side and the other to the lower side.
now I'm confused, is the vibration coming from the upper side which is pulling or the lower side which has the slack?

I put the the brp damper pulley which goes on the top , all vibration gone. Now saying that I am keeping a very close eye on pulley and bearing. I only have about 4000 Km on it so we will see.

:congrats:

Two Words for you: Doc Humphreys! :clap::firstplace::2thumbs::bowdown:
That is the one I’m leaning to but was wondering why there are 2 different kinds. The Smooth Spyder says that it wont work with LDT’s because they can not bolt to the air controlled shock.
 
First i need to get the dealer to check to see if the tension is right. I did not have much vibration on my ST.
 
I will be going on my second summer with the Smoothspyder tensioner. I have ZERO vibration and ZERO worries about the bearing wearing out. A little pricey but you get what you pay for. High quality. Very solid build.
IMHO :)
 
I have about 16,000 miles on a Smooth Spyder for my ‘16 F3L. It cured the vibration issue and is built like a tank.
 
Its interesting that both Smooth Spyder and Roadster Renovations approach it from 2 different directions with the same results. :2thumbs:
 
I wouldn't even consider a BRP tensioner after watching this video giving a comparison.


Wow, been a while since I did THAT video! At the time of this being made, the BRP damper had just come out and there had been no failures at that point. Kind of neat that what I said proved out. Anyway, I have had many improvements since this video and I will try to list them all by their order so that there is no confusion.
1. We changed the aluminum roller to nylon. On our initial testing on my Daytona we found that the aluminum scratched and transferred that lightly to the top of the belt. The nylon does not do that. As far as longevity, we replaced a roller the other day for a customer that had some noticeable wear. It could still have been used, but since I was servicing his unit we replaced it. He had 40,000 miles on it. The bearings were still perfect with no wear.
2. We increased the diameter of the pivot spring as a few of them were failing. This also happened to the BRP units also.
3. We determined that since there was very minimal adjustment on the BRP kits, we would be unable to offer just the arm. They were not getting into a good enough position. Our brackets are slotted and allow for more adjustment.
4. We began to find that the BRP units' pivot point was seizing up and locking up away from the belt. We added a outer seal to keep grit from getting into the pivot. We also added a grease fitting to make maintenance easier.
5. We included an adjustment block that allowed perfect alignment with the belt.
These changes have been in place since about May last year. We have not found a need to do any more changes. We still warranty everything for 1 year and the roller and bearings for 2 years.

Thanks Doc,
I could not find a more recent video that did a comparison as well as that one did. I did however see that you had made some improvements. I just ordered one, Thanks.
