Ok guys just got this banshee this weekend and it's making an almost grinding or knocking noise. I rode it a few times didn't notice any noise or anything but all a sudden I heard it it's not very loud but it's there might not be anything but better safe then sorry sounds like it's coming from the bottom end. I bought it with supposedly only "5" hours on it put about 5 more on. I was just wondering what's the best complete rebuild kits? I will be mostly trail riding and riding gravel roads. The kit can't be over $1500
