Motorcycle Repair: 1978 kawasaki, open pipes, clip position

Question
hi m8, ive got a bog standard 78 z650 engine with new k&n cone filters and open pipes, i need bigger jets for a faster fuel flow, i was wondering if you new what number jets i needed, Thanks for your time, Rob

Answer
Hi Rob,

I can do the math and calculate corrected jetting if you provide the following data:

Current jet sizes, air-fuel screw # of turns out, needle clip position

Elevation

Average air temperature

The calculations will vary a bit due to variations in the accuracy of the data and the amount of wear of parts.

For our convenience, please include your eamil addy as requested and explained in my instructions.

Respectfully,
Mark Shively
