Jet Spec's???

Is there a chart somewhere that shows the hole sizes for the different jets. I want to drill out some jets I have, but don't know what hole sizes go with what?

for keihin jets?

drilling jets is not adviseable but the size of the keihin jet is the size of hole in millimeters.

160 main jet is a 1.60mm hole.

Thanks for the info. I am a Machinist and deal with tight tol. stuff every day. I will have no problem opening up the hole using the proper drills with a pin vise. Is there a conv. chart for the Mikuni jets too?



mikuni jets are rated by flow.

you would need to measure them with your bits.
