122(?) jet - I don't recall, I'll have to look where I wrote it on top of the carb.
pics of my Xingyue and Znen:
[replyingto=millsc]millsc[/replyingto]One sold in 3 minutes...got one left... It has intake lobe widest point is 25.78 exhaust widest point 25.67.. lift is 5.86 LSA (Lobe seperation angle) is 119 degrees. Meeting the criteria for an A9 cam Also have a slightly used (20 miles or so A8 cam) It has intake lobe widest point is 24.48 exhaust widest point 24.52.. lift is 5.02 LSA (Lobe separation angle) is 116 degrees. Which meets the criteria for an A8 cam.
A8 is a good midrange cam for stop and go city traffic...where you get a quicker take off. A9 has great midrange but really excels in top end for you speed freaks...on a good running BBK engine with a level surface and proper roller weights...you will go beyond redline and 50+mph.
