quality servicing

hey guys bit new to the forum but im wondering if anyone can recommend a good workshop to get some servicing ect done. I ride a 91 zx2r live in melbourne and am looking for something around south melb, port melbourne way but happy to travel a little for somewhere reliable .
have had trouble with the last two places i have used, one taking 3 weeks to replace the cam chain and another for some reason putting some sort of degreaser on my brakes and letting me ride off without so much as a warning. Any ideas or recommendations would be much appreciated!!!

Cheers

Rich

hello
have you tried brighton kawasaki? dont tell me one of the shops was sumoto?? absolutely shit house

there is a chap in town near the mec ( jeff's shed)head down city road to the light rail overpass...pull a quick left just before
you go under it (that's an illegal turn but jump kerb just before lights) he's a grumpy old cuss but treated me well when i worked in area....reasonable prices and to my limited knowledge reasonable workmanship..
forgotten his name and business name is small shop just off that corner.....ring preston m/c club if you want details think he's well associated with some of them (that's where i got my recomendation from)..........or brighton kwaka
