I too have been on the end of piss poor service from Fowlers. My local bike shop (RD5 in Warringto, who are great by the way) use Fowlers for parts. When I came to renew my chain and srockets, for the second time, they called Fowlers for a chain and sprocket set. Fowlers stated thet Suzuki did not make a set and I would have to buy the bits seperately, however when I told RD5 the part number, obtained from Suzuki GB's website, Fowlers said 'Oh we didn't know about that set.' What plonkers.
Now if I want parts, I just go direct to Robinsons Foundry in Canterbury, they normally deliver within a couple of days, and know what they're talking about.
