New jets on the new motor

[BANSHEEFIEND]

A little info on my story. I get t-5s, put them on, push shee in yard, go to work. Dad and friends come home, friends ask about the quad, dad doesn't notice new pipes, fires her up , spins around the yard and melts a hole in the left piston. That was a nice suprise when i got home. So he finaced the new motor build and i picked up some wisecos, 19cc trinity head, boyesen power reeds and a new k&n . I already had the 35mm single pwk so i am a little happier now. Almost ready to fire her up and i was wondering what i should start my jetting at. I am in Wisconsin, 750ft. elevation and it's about 20 degrees out now. One more final question. When first starting her, should i break it in, then jet it, or vice versa? Thanks for your help.

Start out around a 195-200 main and a 65-68 pilot. My guess is you'll end up somewhere around 190/62.
