hi all,i have a 1978 Z1R and was thinking about replacing the carb jets etc,at the moment on ebay there are complete kits for sale(from Germany i think?)...now i'm kinda new to this bike fettling lark....but i thought the correct sizes were..main jet 107.5 and pilot jet a 15.?...
The kits on ebay listed as being for a Z1R have the main jet as a 105,wich of these sizes are correct?...and if i fitted a 105,what difference would it make in performance?
Also,does anybody know where i can get the correct kits in this country?thanks

There would probably be sod all difference
Best not to go too lean tho
Jets are only about £3 each

try NRP instead.

std mains are 107.5 is its a 1978 Z1R .............

thanks for your help guys,yes it is a 78 Z1r....if jets are only £3 each then the start price for the kits on ebay of £84 are a bit steep haha!..will phone
nrp instead me thinks!
