Ok I was running a 162 main, 3rd pos w/clip on the needle a 42 pilot with 2 turns out on the A/F screw in 70-90 degree weather. Where should I start with for winter. I am at 500ft and ride in 0-30 degree weather. I was thinking a 172 main, 4th or 5th pos w/clip and 48 pilot. Any input. I have a Rossier exhaust, uni filter, and outwears airbox cover.

5th clip on the needle is prolly a bit much. 4th at most or get an HRC needle.

A 45pilot should be more then enough.

The main u'll have to test.

I use 45 pilot 4th postion 165 main with lid on but with about 25 3/8 holes around the out side works great keeps snow of filter.(my outwears always plugs up with snow,.)and still lets alot of air in a 175 or 180 with no lid should be about right. my 2 cents
