Serval Jetting Help


Recommended Posts

So too start off I'm pretty new to banshees. I recently changed motors I bought a 421 ported serval and I just can't really figure it out so I need your guys expect opinions. It idles fine but it will bog/hesitate when I give 0 to about 3/4 but at full throttle it takes off.

 

I currently have SLP pipes

28mm pwk carbs jets are (170 Mains)(48 pilots)(Stock needle jjh on 2nd Clip)

Air screw 1.5 turns

Elevation is 800ft

Compression is about 150 and 145

Turn the air screws all the way in gently, then back them out 1/2 a turn.

Put the needle clip in the 4th groove from blunt end of needle.

Make sure carbs are sync'd and idle is set to ~1,500 rpms.

Make sure float height is in spec too.

 

More than likely you'll need to increase your pilot jets.
