thanks for all the replies. this site is great. i was wondering, what company sold the best jets. I've been riding for a while but i wanted to really learn how to work on them. Also, i was wondering, what people with the 2 into 1 setup thought of it and how it ran compared to stock. I heard that it had a lot more bottom end, but it's been so long since i've rode a stock banshee. my brother has a yfz450 and it can stay pretty even in high gear. well thanks again for all the replies.
