I need help i just got the velocity intake and purchased the FMF titanium4 full exhaust and iam not sure what jets to use or even how to figure it out. i was reading your colum and noticed a lot of stuff i dont understand like the fuel screw turns or the size of the jets or temps and elevation. Well i live in san diego so temps are usaully between 50-80 at sea level but i love to go to the desert but i am unsure of the elevation. any help will be great thanks.

Hello,
I´m new here and have registered for one question.
(I have no quad, but a keihin carburretor from YFZ450,year 2004)
I installed it in my husaberg enduro.
I´m surching for a good jetting, and have spend a lot of time in the web.
(It´s quite plain to me, that your jettings must not be the best for my engine (501ccm, longstroke), I will not just copy this )
The stock needle was a NDS-R
The most people here changed to NCV-Q
looking in the keihin.us needle chart
http://www.keihin-us.com/am/_media/p...jetneedles.pdf
the needles are termed OC-XXX
(OB is possible too, I know the difference to OC)
Is a NCVQ in full term OB-NCV???
This is improtand for me to get information about the diameter and so on.
And when this is right, was does the smaller fourth letter "R" mean?
for example Kawasaki has a NCVR needle in the FCR40 (KX450F Motocross...)
thanks in advance!
