    I've bought new K&N filters to replace the standard air box on my 89 ZX10 as it is a nightmare to re-fit.

    When I bought my ZX10 it had the standard air box with a K&N filter but the rubber of the filter had perished so I threw it away.

    I know that the main jets on my carbs are 130 but will need to check the pilot etc.

    Has anyone fitted these filters and if so did you adjust the jets etc and to what values?

    • I fitted them to my 1000RX and had to re jet but can't remember what to, it ran dreadful until i did.

    • After much investigation I will also fit a 6 Sigma stage 3 jet kit as I am taking the bodies apart to be ultrasonically cleaned. So I am going to do the job properly.
