This is the post that I have found on what jets I had fitted in the GPZ Carbs
Ok I have stripped down the GPZ500,
Cleaned them up and checked what jets are in them,and they seem to be 134 main jets and 35 pilot jets,
the needle is on the 4th clip down?
Any Help on this would be helpful the bike is running Pod filters and a CSR 750 Twin Standard exhaust.
