Anyone use 4 x Mini "cotton-reel" rubbers for exhaust instead of 2 laverda?

[bclark]

I saw mention about using 4 x Austin Mini cotton-reel style exhaust rubbers (about ?4 for four) instead of the ?32+ for two laverda ones - anyone have any experience with this?

I havent but I can see no reason why not.

Hi Brian - You could use almost any sort of rubber mounting - but as the really smart bloke selling them on e-bay ATM says "there's nothing like the originals" - if you ask him nicely i expect he'd sell you some a bit cheaper off this forum   - Regards - Phil

Brian,

Saving at the wrong end imho...

The rubber mounts usually used in mounting car exhausts are too soft for the applications where the double mount is specified on our bikes.

On the car exhaust, the mount is tensioned lengthwise and allows the exhaust to wobble around a fair bit.  If mounted in a horizontal plane, it will allow the bikes' exhausts to sag  and stress the headers and collector with their weight.  The mount isn't intended to be placed under shearing stresses, eventually the rubber will part company from the steel flanges.

If you really must use single mounts, search for non-waisted items with a slightly increased Shore-hardness, these will offer a great deal more radial support without sacrificing vibration isolation.

If made to OEM quality, the double mounts last almost forever.

Your choice...

Seem to remember I had a go many years ago when mine broke and the local Lav agent wanted a "fortune" for a replacement.
Seemed OK when handled but once on they were too soft. Support and alignment were an issue.
Ended up getting the real ones.
May be worth trying the ones you are looking at but have you tried Wolfgang, don't think the last ones I got from him were that expensive and he does a "stronger" type which prevents the bolts turning.....

The main problem is that the mini bobbins are 5/16",not 8mm!

Laverda exhaust can mounts aren't 8mm either, they're M6

The single rubber mounts are easy enough to find with M6 studs and are cheap as chips.

These ones have a 30 kg rating, so two of them would be 60 kg. Should be plenty strong enough to support an exhaust muffler.

Yep, after the ones perished on the yellow peril, I perused the 'Blackwood' catalogue at work and came up with items that fit the bill perfectly, two that replaces the original item; only thing I had to do was enlarge the holes a bit. Been on the bike about five years without any problems.
Blackwoods is one of those companies that supply the industry and trades-people with all kinds of things. Not sure where you are but I bet there is an equivalent in your neck of the woods.
Hope that helps!

if you buy radiator mounts from Renault they are 6mm
still no good as mentioned above they sag from outset and soon let go.

Not all Laverda exhaust mounts are M6 Cam, here's a pic of an M8 exhaust mount.I suppose it all depends on the breadth of your Laverda experience whether you would know this...

There are plenty of these about from many cars, a trip to your friendly exhaust centre is worth a try.

I used them to mount facet fuel pumps on my karts and not sure but think they were Renault.
