    So who makes the BEST rubber muffler mounts ? About to replace Gastank studs with them .As well another set of muffler ones that have separated at their plates.

    The best that I've ever had were trade-marked 'Metzeler' . I don't know if or where they're still available but if you find them, they should be OK

    Walridge has stainless mounts on sale thru the end of the month at 6.20 each, nuts included. Part number 06-0622S/S. It's in the sales flyer.

    One of the ones I bought recently from Norvil fell apart while I was putting it on. I had an old one I put on to replace the broken one. While buying some rubber mounts for work I noticed that McMaster Carr sells some that look identical with different rubber options for severe conditions and based on the cut away pictures the construction looks better with a price that is comparable if not better. That is where I will buy mine the next time. McMaster Carr calls them Vibration Damping Sandwich Mounts and their website is http://www.mcmaster.com/

    For a few years I worked as an electronic technician with the Postal Service and I found on some of the automated equipment (mostly Siemens) they used those same vibration dampening sandwiches. They are probably a standard item in the industry. I bought a few from RGM and one of them broke right away, the stud was defective (nearly hollow). You may have better luck with McMaster, but not sure, they come in natural rubber, neoprene and SS.

    Pulled the long studs (that can lead to stress cracking),the muffler mounts screwed in easily yet sit home a little shorter in overallength. It can't be that easy or can it ? Gastank rears seem just as easy. Found a bagfull from previous lives and 2 were marked Metzler,look like new ,surround rubber bonded to plates. Much better than all the other genuine ones separated at the plates or about to..

    Hi,

    I have been fed up with the rubber mount design as long as I can remember. At the last national rally in New York I needed to find a good used one to replace on that had failed. I had several guys looking at dozens of bikes.....and we could not find a single one that was ok. Sure they were still installed but none of them could be used as they were all compromised more or less. Just comes back to the design and the stress back there considering the lenght of the exhaust and then add vibration, well its really no surprise.

    Anyway I decided to figure something different out. Currently have a couple of prototypes finished and will just have to get some miles on them (a bit hard as I woke up to 16 degrees this morning). The mounts are nothing like the stock ones and if they test out ok I would imagine that they will be a one time replacement....and thats it. Never have to deal with them again. This is my plan and it will probably be another 2 months or so before they are in production and ready to go.

    Best i've found so far are Harley Lord's mounts which i often grind a waist in. Will stick with traditional replacing on factory Trixie but on Peel will re angle the plate mount to 45' and relieve some sag strain via springs suspension. A fixed cradle mount implies a good long support or long amount of muffler hanging free which I can't get away with for long off pavement.

    If I knew how much better a pilot than mechanic I am -should of just saved up a bit more, at once, and got a CNW custom and act like TV mechanic wiping off finger prints after the professional over haul with time and change left over for the trips.

    Even though I have secured some exhaust systems to the engine cradle, and found that it can work, the parts I am working on would be a direct replacement for the exsisting rubber mounts and will use the same mounting plates as well.

    All I need is test miles at this time.

    Well I'm hoping for a long run of sunny days out Colorado way, then!

    Sorry to bump an old thread but in the time since this thread the CNW Stainless steel coiled muffler mount has made it to market (which I assume is what Matt was teasing us about) and I'm intrested if anybody is in a position to give us a review, I'm very intrested as I was just about to start fabricating brackets to mount direct to the cradle, but these look a hell of a lot less hassle, more road time less garage time! :)

    Been an interesting development for sure.

    Had some test batches made up and even though they were not quite up to par as far as looks, they held up nicely over time and miles.

    Went into production and these were made like I wanted them to visually but because I wanted a more substantial weld, I had some that started breaking right at the welds ( if anyone bought any of this style and didn't let me know about a breakage, do contact me as I will replace them)

    So then I decided to heat treat the entire piece after welding and then we had zero failures

    Next batch of springs I got (we are doing all the welding in house) were then dimensionally all different. I managed to make many sets but it was getting harder due to the different sizes. Fact is I have used these on machines for 4 years now and many have been sold as well. Great feedback (with the exception of the few that broke of course)

    At this point I have decided to remove them from the parts catalog until I can get a consistent quality and style made to where we can offer them again

    So its coming down to the spring manufacturer and I have another batch in the works that will hopefully be just right

    That's the story so far.

    I've been running the soft silicone ones from McMaster, good durability and compliance so far

    At this point I am taking orders and shipping them on a availability basis since I keep making small batches.

    Full blown production will not happen until I know my suppliers cab deliver what I need

    So send me an email at the shop, nortonworks@fone.net and I will put you on the list

    Thanks

    I think there is 2 important aspects with the OEM type muffler/headsteady mounts.

    1. The rubber has to be fresh. I am sure many have purchase oem items which were new but very very old, just like buying tires at deep discounts.

    2. The exhaust needs to come together without (or at least as little as possible) stress points. Even the freshes rubber will fail if under constant pressure from a poorly fitted exhaust.

    Fresh rubber and a good fittting exhaust will work for many years and the mounts will do the job that they were design to do.
