Whats up, I just joined here. I have had couple 4 wheelers in the past, but last week got a 2007 yfz450. Its had about 5 or 6 tanks of gas thru it, looks brand new. He went up 1 tooth on front sprocket, other than that its stock bill balance edition. When first taking off, it runs good, but when its in 4th or 5th gear, if you let off throttle and get back in it, it stutters pretty bad. It even stalled one time when i was in fifth, I let off and tapped throttle and it died. It started right back up, but cant be right. Any ideas? I am going to run this tank thru it and then was planning to take and get serviced and checked out.
