Don't flame me for not doing a search on this because I checked the first 15 pages and couldn't find the right thread.

Alright I just ordered a HMF full system and am running with a K&N + outerwear, and the air box lid is ON. I ride at about 1,000 ft above sea level.

On the HMF sight it says to run a 200 main jet but that seems WAY too rich. Where do you think I should start with the main jet?


PS: How will my 400 with this pipe compare to my friend's stock Z400?
