Jetting a 1982 GPz750

Just curoius hoew this turned out for the the OP. I am wondering about my jetting for the same bike biut with stck carbs. I currently have 40 pilots and 127.5 mains with the stock (nonadjustable) needle. I was toying with the idea of going up to a larger pilot. I am running the stovck airbox with a K&N and a Kerker 4 into 1.
The problem I am trying to solve for his a dead spot right above mid throttle where the bike just gets louder but doesn't accelerate.

I wish I could help you but I never got that far. I had a bad cylinder, and two striped sparkplug holes and more. The engine was rebuilt and now I have no spark. As soon as it fire up I'll let you know how the carbs work.

FYI, I have a Mac 4 in 1 and generic k&n style air cleaners with 115 main jets and 37.5 pilot jets.

The metal cover on your pilot jets can be popped out by grabbing them and pulling them out , they have an O ring that holds them snuggly in place, they do not need to be drilled out It is recommended that they be put back on as the pilot jet is fed through a passage in the main jet, not having the caps on will cause a direct fuel feed to the pilot jet and will get too much fuel, make sure the passage from the main jet to the pilot jet is clean, the metal cap that sometimes need to be drilled out are outside the carburetor body and it is used to control your air/fuel mixture.. Also if you click on the Articles icon at the top of the page, a pop up will come up, and if click on technical tips, now you can have access to Carburetor Cleaning 101 and 102. As far as jetting goes there is a formula that you follow somewhere in this site, maybe someone else will chime in with the formula. Hope this helps.
