He has not changed the jets from what was in the carbs. I think they were 134’s but can not say if that is standard for the GPZ500. The carbs will go straight on the CSR, LTD and K i think too as they are 34mm. If they are to be fitted to the B models and G then they would need CSR/LTD rubbers on the head or you can use Suzuki GS500 rubbers with a 10mm spacer at the head.
There is a better running link in the gallery forum
