Jet number to Jet diameter was created by Austin440
The jet size on the pilot jet on my KZ 440 is mostly scratched off.

1.) Is there a chart somewhere that describes the relationship of jet size numbers to hole diameters? I have access to a gauge pin set so I can get the hole diameters.

2.) Does a #55 sound about right for a pilot jet on a carb that size.

3.) I believe my main jet says 88 but I'm not sure that size actually exhists. Although I believe I have to go bigger so exact size doesn't matter as much - I just need to know that I'm in ballpark range.

Thanks.
