Pat Creagh's used to do this - he made some adjustments, then I sat on his bike and tried it out and no more squeaks - but it did piss its oil out onto the drive
Now I understand it is back from Harris and all better now.
Mike (or anyone else for that matter), if you want me to sort out your Ohlin squeaks just send me a cheque to cover my expenses and I'll come over and sort it for you
