JD Jetting kit installed - nice mod

I installed a JD Jetting main jet and needle kit. The recommendations in the kit were spot on. The afterfiring (popping) on deceleration is gone. The stumbling at less than 3000 rpm at 25-30mph is gone. The engine will steady idle at 700-800 rpm. Starting is better. With nice roll on it will pull from 2000 rpm with to past 7000 rpm without hesitation. Above 3000 rpm throttle response is quicker and smoother making throttle steering input easier. At dead slow idle riding using the clutch and rear brake it is really nice.

Thanks for the good report Slowpoke! I've been thinking about putting a jet kit in and your report helps to make the decision as to which one!

Question Fuel Mileage

Have you had time, or distance, to calculate your fuel mileage?
Did your mpg increase, decrease, or no change?

We live and cruise at mostly 1800 ft - 2500 ft. Our western high plains are 3500ft.

Stock - my carb had a 145 main jet and the idle circuit was at 1-3/4 turns.

The kit comes with 2 needles, each with 4 adjustments. It comes with um... 4 jets (I think). The kit comes with instructions and jetting recommendations for high altitude and engine mods.

99% of my closed circuit" riding is below 4500 ft, stock exhaust - so the JD recommended adjustment is: blue needle, clip in #2, and a 160 main jet. Idle circuit at 2-1/4 turns.

My bikes have always burned all the gas I put in them. -

but no I haven't had a chance to ride enough under similar conditions to compare fuel range. I'll post the numbers when I get a chance to check the range out.

Did the JND jet kit and Leo Vince slip on. At sea level, the 2 1/4 air screw is too lean, slight popping on decel. Thanks to dave for outstanding instructions. Increase in all power band, not too loud, but WAY better than stock!

My mileage may have dropped by a couple MPG, but it could be that the bike is just that much more fun to twist to the stops with the JD kit and new pipe.
