In the next few weeks if all goes to plan I'll have in my possession a few sets of these rubbers. I've already sold 3 sets of them and I'm thinking of keeping 2 sets for myself so that will leave just 1 set spare. Anyone interested? not 100% sure of cost yet as we don't know the price of onward posting from Europe where they are made and of course how much it will cost me to send them onward to the buyers but initial sums are leaning toward somewhere between £55-60 a set. That's comparable to the price Max charges for a set for the 400-4 and AFAIK Max has no plans to make these due to the odd shape of them.
To fit them will involve you drilling off the heads of the rivets holding the large gear onto the back of the basket, removing the remains, tapping the towers to 6mm and countersinking the metal plate fitted to the back of the gear. Not hard but not exactly a doddle either.
As these bikes get older the chance of the original rubbers going rock hard increases and that can cause the gear on the back to move back and to, this creates lash in the drive train and will almost certainly shorten the life of the primary chain and it's hub rubbers. It also accounts for some of the noise at tickover. Replacing them should smooth out take off and deceleration in theory if nothing else.
I may buy some more sets in the future providing the person buying them for me in Europe doesn't mind doing it again, however these may be the only 6 sets imported as the maker of them will not post to the UK.
The inside of the basket looks like this when it's apart, just for reference. If you look carefully you can see where the rubbers are splitting at the corners.
First one to say yes on this thread is the winner, no PMs please.
