Important notes about CV carb tuning
To properly tune, you MUST:
1. Have selected the BEST main jet for full throttle power (not just a "good"
main jet - we mean "the BEST main jet" for power at high rpm).
That eliminates the common severe tweaking of the midrange
and lower tuning ranges to compensate for a "wrong" main jet.
2. Then - select the BEST needle height / clip position for power at FULL
THROTTLE / MIDRANGE after selecting the BEST main jet -
That almost eliminates weird problems at cruise caused by
tweaked needle heights that were required because the main jet wasn't
correct.......
3. Then, adjust the BEST Float Height for BEST FULL THROTTLE / LOW rpm (many
Honda's excluded because floats are not adjustable) -
You should be able to apply FULL THROTTLE at LOW RPM in TOP
gear without ANY misfire of bogging or stumble.......
If you follow that order, you will have:
1. Best topend.
2. Best midrange.
3. Best low rpm power.
Then - all you have left is dialing in the pilot circuit - i.e. mixture screw and pilot jet size - That's IT - Don't tweak needle heights and throw away full throttle midrange to try to fix a cruise issue (Unless you want to)
If you reach an impasse in steps 1,2 and 3 in the FULL THROTTLE tuning, STOP and call TECH SUPPORT.

and 800 869-0497, ask for TECH SUPPORT -
