Recommend me a fuel tap repair kit

[Crass]

The fuel tap on my 750L will not turn to the prime position.  It used to when I bought the bike about 18 months ago and it had been stored for several years prior to this.  Now it won't any more.  I suspect something old internally has swelled with the ethanol in the petrol and needs replacing.  Thing is, looking at a lot of the rebuild kits advertised, 1) most seem to be just giving you bits for the vacuum operated diaphragm - that isn't the problem, and 2) I have heard some are cheap shite and don't last.  Anyone bought a decent kit with all the bits to repair this kind of issue which has lasted?

Yes tourmax kit! Of that site are fairly good little rubber grease on assembly ! Used them for years pretty happy with them.
