Hi all reading posts earlier on Head steady has make me think a bit deeper (worrying i know)
As the rubbers in the ISO's will settle ...gravity has a lot to answer for, do any of you place a jack or support centrally under the engine/cradle & lifted slightly to take the weight of the ISO rubbers through the lay up??

Good question,I am wondering that myself
 
I'll be first in the hall of shame and say no..... though I'm guessing the rubbers suffer more when the engine is leaping about during combustion than when dormant (assuming they haven't been contaminated in any way)....
Just a layman's view...
(You could always turn them 180 degrees on start up :-) )

Well you say that Baz and hindsight being a wonderful thing... if Mrs B had worn a Bra in her earlier years we would have the problem we now have:D:eek:

wouldn't use of the main stand (cradle mount) accomplish the same thing?

No, its the change to the cradle mounted centre stand that is the cause of the problem as the stand now pushes the cradle upwards against the bottom of the iso's to lift the bike, the weight of the bike minus whatever weight the one wheel touching the floor is supporting is all on the iso's. When the centre was frame mounted then being on or off the centre stand had no effect and the iso's took only the engine and gearbox weight.

I have stored my bike for nearly 40 years on the centre stand so pointless doing anything now, but even if I ever took it apart I would only turn the iso's around 90 degrees so the steel tube was back in the centre.
 
Have always used the side stand so there is no weight on the ISO have replaced them once in 50years..nothing to get too excited about
 
Yep don't worry about it
I've never had a centerstand on any of my commandos in 40 odd years and I've only changed iso rubbers once on one of them and that was because the rubber was perishing I think ! But I can't remember, never had a problem yet with the rubbers settling through winter storage
Maybe others have?

There is no problem with rubbers in good condition. They only go out of shape with age after losing some of the elasticity as the rubber hardens. Do you worry about the suspension springs?
 
Think I might keep riding over winter, then my suspension, isolastics and wet sump get a regular workout. But which oil / tyres should I use in winter? :(

Assuming you will be going out on the odd bright dry day (not go riding through blizzards, if we get any?) and already using multigrade engine oil then there shouldn't be any need to change either oil or tyres.
