HMF slip on is ordered, gonna do that with jetting and lid off. I rode a 300ex before, but it was back in the mid 90's. I now have a Raptor 250 as a second quad/wifes ride. To me the Rap feels "quicker" than what I remeber the 300ex being. But agin, that was a long time ago.
By the way, this is just all in fun. My buddy and I both have 450's, but his spare quad is the 300ex. He was trash talking the 250, saying he'll mop me with the 300 lol. We are gonna get together and do a ride with the smaller quads just for the hell of it. Should be fun!
