How much did they sell for?
How much of a performance increase can you expect?
That's kind of between him and I but I can tell you from what I paid for them and for what he's paying for them, I took it in the shorts.
I really didn't need them anymore because I traded my shee for a raptor and my boy's banshee aready kicks my raptors ass so I sure as hell didn't want to give them to him.
There was a noticeable increase in performance from the bottom to the top with these. Plus, they were a lot easier to get to the main jet in the carbs.
