    Tracing down a vibration problem , so I installed the Heady Steady we won at the rally two years ago. Thanks so much Jim C. :D

    It helped at the low end rpms but didn't help so much at the high rpms, I had a Norvil iso , with shim type before.
    Turned out there was a reason for the vibration. See the photos :shock:

    The front mount was shot, I rebuilt it 20 years ago, who would have known? :roll: :roll:

    You could have pumped in some RTV silicone and let it sit overnight; would'v e been almost as good as new.

    Did you use 'normal' grease to help with re-assembly all those years ago?
    If so, don't use a mineral oil / petroleum based grease this time around. Talcum is as good as any lube for this job then seal with silicone.

    yes! that would have fixed that old rotted ISO up as good as new

    just like the old master mechanic trick of throwing clutch plates on the garage floor, stepping on them to grind them into the concrete to clean them

    and presto!

    them clutch plates are now perfectly good to put in your bike!

    actually did that to clutch plates for years and it worked. I might have used the wrong grease, not real sure but now I have something that should work real well.

    Update on the motor mounts, the rear mount rubber was real nice ,replaced it anyways, it did have a little sag but that's it, compared to the front it was like new!

    Did you get access to rear iso without removing too much? Please share your proceedure for those less enthusiastic!

    I found 'Iso's easy to fit with a push and corkscrew type motion, but once in place the rubbers need to be vertical in the tube, not distorted in any way and not in a sea of lubricant.... That is the tick imo.

    Is the Norvil head steady the better design. ? (mini Isolastic)

    Yes I've only ever pushed new Isolastic rubber fittings in by hand per Time Warp, with red grease (Dunlop I think). I don't even have a bench, let alone a press. To try to be safe, I've pushed them in a little too far, then back into position. Only done it three times though so what do I know. Twice at the front and once at the rear. One time around at front and rear fitting N*rvil adjustables, then the front a second time because the N*rvil rubbers were rubbish.

    I had one of those shimmed affairs, It took forever to get aligned so it would not allow vibration into the frame. There is too much twist and misalignment up there to get it just right.(Maybe the front iso was bad when I was running it?)

    Are you sure you didn't swap iso's with The Titanic before you dropped it off? Those are gnarly.

    10" cabintemaker's bench vise with appropriately sized sockets over both ends makes quick work of ISO rubber installation
