Very informative! Glad I didn't do any porting to the cylinder...yet. By reading your post I see I need to go probably a size or two bigger on pilot and main. What is your setup? So far I run pretty well until I get up into the near 40's then the 4stroking starts. Especially wot. I've read the main jet doesn't come into play until wot. If that's the case my pilot needs to be around the size of my main jet (idk anything about jetting) and my main jet probably needs to go back to stock 105. If I made any sense lol
