Im doing some mods and not sure where to start with tuning. I currently have t5s, k&n pods, and vitos superstock pistons at 65.00. I will be adding vf3s, a pd coolhead with 21cc domes, and a timing plate (probably just set at +4 seems to be the popular choice). Im using stock carbs. I will be riding between 800 and 1200 feet. I was thinking like a 330 or 340 to start but havent done a lot with jetting so Im hoping to get some other opinions.
