stock carb 101 help

[[email protected]]

Trying to tune a bike , that is lightly ported , lightly shaved 135psi, +4 timing, stock carbs , stock pipes ........

 

can anyone get me around a base line to start , im totally clueless only ran kehin in my time.

 

What is a stock banshee jetted at, mains , pilots , clip setting , i am guessing thats my baseline...... would i go richer or leaner with porting on the main.... the stock pilots should do fine just maybe richen it up till shes a wee bit rich .

 

can anyone clue me in on stock carbs

K & n open lid or closed wichever u thinks better

[batoutofshell]

if you open the box its gonna go up at least 4 on the main, I would say if you open the box go with at a 260 and work your way down with plug chops. my 2 cents

I would agree with the above...

2-4 sizes on the main with a K&N and no lid...and porting is the wild card...

 

I went from a 330 main in mine to 350 with a cleanup port 4mil cub. It is possible you actually go DOWN a main size with porting, now that the engine is breathing more efficiently...but, 260 with no lid is most definately a safe starting point...
