30mm cpw carbs

[robsully5150]

I just recieved a set of 30mm cpw carbs for my banshee and I was wondering what jet size I should start with. In my stock carbs i ran .270 mains. and stock pilot jets. Those carbs ran great with my old setup. I just got the bike bored and a mild port job done on it. I ride trails and tracks mainly. I have full fmf and reeds and k&N all the basic goodies. Im just trying to find a starting point for these bigger carbs. Do I use a smaller main jet? I think cpw sent 155 and 160's with them but i dont want to way under shoot the jetting. I have used the search engine, and it's hard to find anything about CPW carbs or 30mm so any and all help would be much appreciated.

I was thinking about getting the same carb set up, how much did you get them for?

148-160's usually. So they got you close.

STAY ON POINT GUYS HE HAS A QUESTION ANSWER IT OR JUST VIEW.

 

What is your altitude? I am at sea level and have about the same mods. I run 160 mains and 50 slow jets, air screw at .75 turns, and the supplied needle on the 3rd clip.

Mods are in sig., and I run a 160 main, 48 pilot, supplied needle in the 3rd clip, and air screw out 1.5 turns. I am also at sea level.

Hey guys this is a pretty old post but I thought I'd stick to it and not start a new one.

I just recently purchased the same set of carbs (30mm D slides) and was wondering if these jetting tips worked out?

I'm running T6 Toomeys with Vforce3 reed cage & boost bottle, stock bore.

 

I see 160 mains and needle clip position on the 3rd seem to be the norm but what about the pilot 48 or 50?

Turns out - .75 or 1.5 ?

 

Also wondering what type of air filters are you running / had best results with?

K&N airfilter with airbox lid or outerwear.

 

Non ported i think 150 main and 50 pilot will be real close needle in 3rd clip

 

Ported,maybe 152-158 main and 50-55 pilot depending on pipes.Torque pipes generally like bigger pilot and raise up needle 1 clip,top end pipes can get away with 50 maybe even 48 pilot.I run a MX ported 4 mill with FMF gnarlys and Im 155 , 55 needle 2nd clip from bottom..1.25-1.5 turns out

 

I love these carbs,they are very easy to tune.

Thanks BigBore -

These numbers sound a little closer - I'm running K&N pods w/ outerwears. I'll let ya know how it comes out.

Are you at sea level?
