- January 30, 2018, 00:20:28 AMYes remember that and I told you I had a Roadhouse exhaust system and that I had rubber mounted it. Then I guess I never looked at Pearl but it has a stock system and it had a couple of rubber grommets on it. I know that some of the 1500 people had theirs hard mounted, and had issues and some people that used aftermarket exhausts on their 800's also had issues when they hard mounted them. not so much cracking but more a vibration issue.
What system are you running?

Back on Dec 13th I had an inquiry regarding the mounting of the muffler to the frame. The bike I had purchased had the muffler hard bolted to the frame and I thought that it was unusual that on a rubber mounted engine that the muffler should also be mounted this way.
I am here to tell you that I just received my Kawi OEM order and there is indeed 3 large rubber grommets and 3 flanged grommet spacers that hold the muffler onto the frame. Anyone with thiers mounted hard is looking for cracking problems IMHO.

But like I said for the cost, and your already in this far worth the extra few bucks to buy new ones......purpose is to dampen the transition of power from the chain or drive shaft to the rear hub ............
I remember having mine out before on the 1500 and the 800- they both looked OK at the time. Knowing what I know now, I would look closer at them next time I have them out, and maybe just replace them due to age.

- January 28, 2018, 00:31:15 AMYeah my Triumph Bonneville had it too I think the only motorcycles maybe that don't have dampeners would be little dirt bikes or something. I have a 175 Yamaha that doesn't have dampeners. It's very hard on the tranny counter shaft if there's no cushion in the final drive.

- January 27, 2018, 17:39:19 PMThanks, getting ready to pull my rear wheel to lube drive shaft and swing arm. I will inspect them. Looks like one set for 1500 and 4 each for 800.

Yes the 1500 has them also, https://www.partzilla.com/catalog/kawasaki/motorcycle/2000/vulcan-1500-drifter-vn1500-j2/rear-wheel-chain part number 92075 at $74. I'm not sure if that is just one assembly.

- January 27, 2018, 16:45:04 PM Hello, some of you actuaries will have something to say of my numbers but I did this my way and I understand it. I took the rubber damper from the rear hub and measured from A to B and from C to D, I used digital calipers so we at least know the numbers are correct. Now I was told by a couple of kawasaki mechanics, if you lean the wheel over and the hub falls out the rubber needs to be replaced. The hub should have to be gently persuaded to go back into place. If you have torn your rear end to this level then spend the extra $50.00 to replace the rubber and then no more clunking or thunking noises from the hubs.......
Ok so here is my results and feel free to correct my numbers and if I made a mistake let me know. So I took the measurements from A to B and then C to D. then I just added them up and subtracted the sums to see if there was a difference and how much....
here are the results.......
A to B
New Old
39.20 38.12
39.26 38.14
39.26 38.28
39.26 38.09
39.30 39.00
39.30 38.08
39.30 39.07
39.30 37.91
------- -------
353.48 306.65
C to D
New Old
35.60 35.77
35.55 35.48
35.67 35.21
35.54 35.43
35.17 35.66
35.22 35.18
35.81 35.42
35.85 35.52
-------- --------
284.41 283.67
then the results are like this between the A and B classes it is 46.83mm then between C and D is about 0.74mm.
You can also see in the extension in the second picture that thf ends had wear and gouges on them. So like I said if you are this far into the bike this should be done,46.83 mm might not seem large but you can still get movement and this can cause a lot of noise as I found out with Red. I wish I had done this with Red.......
