Have people swapped the carby as a result?
Look forward to hearing from you shortly...

I made a radical test this weekend and all the carb problems on the ZX12 dissapeared, and on top of it my lap times dropped.
What I did is got a Nova carb and took it to a lathe, reduced size of throat that goes on to engine to 10mm ext. dia, then made a sleeve from Teflon of 2mm and put it on the carb so i't has 12mm ext. dia. like original, so it acts as an insulator (like the OS or Orion), ...and BINGO...all problems gone, carburation is precise and stable, I made a 25 minute non stop run and pitted every 5.30 minutes...no flame outs and at the end the engine was at 115ºC idling like cat's purr..
This engine has tons of torque and good top end, I kept my pace with the JP'S, Sirio's and the likes with no sweat.....now I'm ready for the race this coming Sunday.
