I'm getting set to do the 150cc kit and am considering keeping my stock carb and having it bored out. I've read alot of talk about various carbs and sizes and even recommendations to have theirs bored out. So...I'm looking for input from someone who has actually had it done to their stock carb. If you haven't but have first hand knowledge please post your experience. My reasoning is I think I'll get better low and midrange than trying to go to a bigger carb. Most of my riding is either single track or on my mini TT track with 2nd gear corners (stock gear). Just looking for more pull coming out of the corners really.
