Banshee carb

[2000banshee]

My banshee has a Dynoport 2 into 1 pipe and silencer, k&n Filter with no lid, 65mm pistons. What size main jets should i run. I have in 270's but the cylinders are not getting enough fuel. I dont know if the reeds are messed up or if i need bigger mains?

How did you come to this conclusion of not enough fuel?

If you think its lean go up a few sizes and see how it runs.

It turns over and has compression, sometimes it doesnt start and sometimes it does. brand new sparkplugs..

Plus sometimes the spark plugs are dry

Clean the carb. If it has been over a year then I would clean them. I clean mine every year. But clean the bottom of them every time I rejet. Here is some food for thought

 

The air screw is most effective between idle through 1/8 throttle. The pilot (slow) jet is most effective between 1/8 through 1/4 throttle.

 

The jet needle is most effective between 1/4 through 3/4 throttle.

 

The main jet is most effective between 3/4 through wide-open throttle.
