400ft, 38F40NEDH31757.0PWK 36initial start
200ft, 60F-80F40NEDH31857.0PWK 36->39oval bore,
slight spooge at the end of day,
lots of off-throttle pipe bang
200ft, 60F-80F40N3EH31857.0PWK 36->39Much crisper.
200ft, 60F-80F40N3CH31857.0PWK 36->39Better than N3EH
200ft, 60F-80F42NECG31787.0PWK 36->39nice
300ft, 87F42NEDH41727.0PWK 36->39Cylinder work completed.
No roughness anywhere.
Even with a very slow roll on, never sputtered, 4 stroked, or surged.
Smoothest running bike I've ever ridden.
300ft, 87F42NEDG41727.0PWK 36->39More powerful feeling, some 4-stroking at low throttle (around 1/8)
In 6th WOT from 30 mph, when it hits about 55 mph, begins pulling HARD.
Got to 78 fast but could have gone faster if more straight road were available.
300ft, 87F42NEDG41757.0PWK 36->39Seemed less powerful about 1/2 throttle.
Lots of 4-stroking and rich roughness from closed through around 1/2 throttle.
Max speed about 78.
No strong pull at 55 mph WOT.
Surprising to me, it sounded better but measured worse for top speed and butt dyno.
300ft, 87F42NEDG41727.0PWK 36->39 Went back to previous settings for a reality check. Still strong 55 - 80 mph pull.
Still has a little roughness around 1/8.
300ft, 50F45NEDG41757.0PWK 36->39 expecting colder weather. The pilot is too large.
Nice brown plug, wet exhaust tip
300ft, 45F42NEDG41787.0PWK 36->39 little crisper on low end. May have lost some grunt. Hoping for more on top.
Needs ride time to evaluate
300ft, 45F42N3CG31787.0PWK 36->39 Fatty, Much more low end. Lost some top speed
tried mains from 185 down
300ft, 75F40N3CG41787.0PWK 36->39 Good
300ft, 45F40NEDG41727.0PWK 36->39 Winter Jetting
300ft, 85F40NEDH41727.0PWK 36->39 Summer Jetting
300ft, 70F42NEDH41787.0PWK 36->39 clip #5 too rich, 178 MJ for high speed
