Title: Jet sizes for YZ250F 1979 Running 250E barrell std 250F pipe
Post by: oldyzman on April 18, 2009, 02:48:12 pm
Gday guys,
Was wondering if someone can shead some light. I have some std specs for this bike:
Main   400
cutaway   3.0
pilot      50
needle   6F16
Air          ???????????????
Needle jet   Q0
the air jet is not listed, I have the spec for a yz250H which is 2.5 should i use this or does it run without one as i cannot see it on the drawing either for the F . And to throw a spanner in the works its running a 1.5mm oversize E Barrell...
Any help will be much appreciated. All opinions will be respected

Cheers
Brett
