hey thanks for lookin at my thread. just needed some help w/ my jetting before i go riding tommorrow. i have a 96 banshee ported w/ stock carbs and just put cpi's on my bike. i used to run a 290 main w/ my fatty's and now jumped to a 330 and lowered my needle clip one position for the cpi's but.......when i took it out for the first time and nailed it, the midrange bogged. the low end and top end were fine. so i went to a 320 main and it got slightly better. so i took the needle back to stock( 3rd clip position) and it still bogs. it is the best it has ever been but it still does it. do you think i should go another notch on the needle to lean it out or go smaller on the main to a 310. the reason why i have a hard time w/ this is because on cpi's website, they recommend 320's and lower your clip one position.........ON A STOCK BIKE. why am i not running at least that on a ported bike?????????? please put your 2 cents in......thanks brothers......

 

The reed block is going to cause it to need a leaner jetting, compared to stock reeds. The recommendation is just that, there can be alot of things changing your quads needs. I would think leave the main alone, till you get the mid to clean up and rev.
