I recently bought from them a new cam chain for my cb350, for 10 bucks (Buy it now was $20 but I waited till the very last hour). They sent me the invoice and shipping to Spain is 6 bucks. That makes a cheap source of parts. I had a look at their other items and they seem to have a lot of aftermarket spares. Probably I will be buying a set of aftermarket pipes for my CB350, I'm being unable to buy a cheap set on eBay. Yesterday a set sold for 212 bucks, while siriusconinc sell the aftermarket for $95.
