Rain held me up a bit - good excuse to research other stuff "I need".
Got out this afternoon with new jetting.
Same 1 min WOT run - out, U turn, in.
Air Corrector - 160
Atomizer - BE3
Main 102 = 40.19 MPH out, 40.17 MPH in
Main 100 = 45.6 MPH out, 41.7 MPH in
Main 98 = 44.6 MPH out, 39.21 MPH in
* took avg of top 3 speeds achieved - and did multiple runs. Should be pretty accurate.
Then put back in the old set up to compare in like conditions.
Air corrector - 250
Atomizer - E4
Main 105 = 42.11 MPH out, 40.89 in
That's a pretty meaningful upgrade with new jetting over best I could squeeze outa old set.
Main 100 not only ran faster top end - it was peppier through the middle.
Hats off to you guys for the input/hand holding!
Would have been weeks of blind search - settled for what I had managed - without it.
I want to go back and re-jet every vehicle I've ever worked on from my teens/20's.
you guys are awesome.
Idle jet was left at 48/160 = 3.33
Tried 55/160 = 2.9 felt boggy.
Perhaps smaller jump would be ok.
Still some room to play I suspect.
Great above 4MPH but first 5 feet still a little anemic on takeoff.
Really tempted to see how 45/160 = 3.5 feels - but little scared I am going to scorch my motor.
