28mm keihin help please

my guess is, once you fatten up that needle, your main will require leaner ?

have you searched thru the 28mm jetting threads for a starting point ?....

thats similar jetting to what i run on my 34 pj and my mods.... 48 pilot, dgh needle, 155 main
my money is on a CPW suggested needle will set you free
 
relay all that info to the dude at cpw tomorrow morning.
if nothing else he'll suggest the correct needle for you, and possibly pilots and mains too.
have your credit card info ready and order while you have him on the phone.
IIRC...he made a paypal request for me
 
im also going to call ct to get the 411 on their titanium needle

Don't waste your time with ct. In my opinion a cel,or dgh needle, 48 or 50 pilot, 150,152,155, main is all you should need to jet that carb.As long as there is no air leaks and everything is in good working order.

i will keep those in mind when cpw gives me a suggestion... ima say dgh as the other guy on here said that as well
 
still waiting on needle from cpw..... the only way it runs good is with the needle on the second clip from top ..... it zings out on the 3rd clip but i understood zingy meant lean not rich?
