How do i adjust the carbs, i removed my outerwears and i want to richen it up a bit.
Do i use the 2 "t" bars coming off the carbs to adjust? tighten=leaner/loosen=richer?

What year and model ski? As a general rule of thumb opening the screws will add more fuel. there are two adjustment screws per carb one for low speed circuit one for high speed circuit. look for the Mikuni SBN manual in the how to section it explains a lot about tuning carbs.

well, the ski runs well now except for a minor bogg on the low end about 30% throttle while planing out. i had a post about why my ski would only run 60MPH and they recommended that i take off the outer wears and that i would have to richen a bit for the increased airflow.
here is the link to that post.

I read the other thread too. my suggestion is fatten em up a little to be safe for the long weekend. Then if you are serious about getting some speed get a Tach a GPS and get some data collected so you have a baseline. Then from there you will need to get into the ski a little and find out what you are working with. Compression Jetting specs etc. it takes some research to make mods work for you, otherwise you are shooting in the dark.
