[Serval Jetting Help]

Well I synced the carbs. Went up too a 52 pilot, turned the air screws out a half, moved the needle down and it still has a pretty bad bog in low end revs, the top end is still good. Could something else affect this other than the carbs?

[Serval Jetting Help]

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
