Quick carb jetting test today

Sometimes I love by job.

If you sit that far back, and yank that hard, the motor doesn't have to be running to bounce up like that.

Thats right, but if you don't get the front wheel up then you don't impress the girl taking the video.

yep, gotta get that front up

The CRS 33mm smoothbore carbs ran better with richer jetting on this test. The "tuned" 750cc required richer main jets than the 850cc customer's motor who had me check the jetting. The "Tuned" 750cc has JS0 cam with lift and duration similar to stock, Axtell copy ports, Free breathing exhaust. Good mid range pull.

120 to 130 mains
YY7 needles with clip 2nd or 3rd from bottom
68 pilots (idle jets)
230 slow air jets
Float height 14mm
3.0 throttle slides
slide gap approx .020” at bottom
idles screws approx 1 turn
#40 starter jets
