Hi guys. When looking for parts for my 1989 gsxr gj23 what web sites are good?. And are they commonly shared parts like engine gaskets. Filter for oil and air. Fork seals etc. Im planning on new air and oil filters. All new engine / radiator hoses fork seals etc first up. Are any parts easily sourced from australia or is japan the go. For the manuals i just pay the ten bucks to dl them hey? Im planning on getting the whole engine vapour blasted and so ill be chasing clutch cover. Rocker cover and sump gaskets too. Are the 250 / across and gj 23 engine basicalky the same unit?.
