I know quite a few Funsters have these-hope this is of help When I bought mine,I fitted it on the coldest day of the year and managed to overtighten the bolts so that one side of the casing split When I got the new piece (£10) I was very carefull not to overtighten it !! so much so,that after a couple of months I noticed more 'play' in the lever and found that the bolts had loosened. I have now retightened them using Threadlock -hopefully that's it sorted.:BigGrin: Mike.
