Hi everybody. I have been checking this site out everyday for about a year now. I have read alot of fun and useful info here, but never registered and joined in on the chatting. Well, I have a 05 Griz with 26" Mud Lites. I put the Mud Lites on it when it only had a couple of hours on it. It still only has about 40 hours on it. I really can't remember what it felt like with the stock tires and rims, but I do know I lost a little bottom end. (won't lift front wheels as easy) I bought an E.P.I. sport/utility clutch kit off of e-bay a few months ago and have been to lazy to put it on. I finally took it to the dealer and am letting them do it. I also told them to check the valve clearence and all the other stuff they do on a first service. I had already changed the oil and filter myself at about 10 hours. Before I took it to the dealer I ran it down the road wide open and got 62mph on the speedo. I can't remember what it did with the stock tires, but i think it was like 67 or 68. What kind of a differecne should I be expecting on bottom end and on the top end. Are there any other mods you guys recomend?(rev box, jetting changes, silencer, air cleaner) I was thinking maybe just an air cleaner and one of those silencer end caps you see on e-bay. Then I would probablly need to change jetting. Any info would be greatly appreciated. THANKS!!
