Kawasaki Z250

I (Graham) finally pulled my finger out and set about putting together the order for new sprockets and tyres for it.  In the meantime Steve and Alan fought to get the hardened and perished rear tyre off the rim.  After a considerable struggle their persistance paid off.  The front brake disc was found to be quite badly ridged so we looked into buying a replacement.  Early searches for a new disc proved fruitless.  There were plenty of discs claiming to be for the front of the Z250A, but not one of them had what I would call the disc centre where the bolts go through to attach it to the wheel.  The original disc is rivetted to the centre and I never seen discs sold that need the rivetts drilled out and replaced to fit new discs.  So it maywell be a case of taking it to a local engineering company to get the disc surface skimmed.  Putting the old disc back onto the bike with new pads would mean that the brakes would not be particularly effective until the pads had worn to match the grooves and then the pads would very likely wear out quite quickly.
