If you bought it from Custom Products just call and tell them your problem and they will ask you to send it in with a letter explaining the problem and they will send you a replacement. I had the same thing happen to me and a the replacment one I got in return was the 2 piece on because they were out of one piece ones.
Well, at least yours does that all the time. When I had my bushy and Cp 2-piece, sometimes it would go in all the way and the CP logo would be on top, somtimes it would be all the way in and on the bottom, and sometimes it satraight wouldn't go in! Threads were clean too...I'd rather wonder than know.
I havn't played in almost 8 months. I just wrecked a brand new snowmobile, bad. Leave me alone.
