Hello all, I was rejetting my bike for the TRC Ti that I recently installed. Everything went smooth up to the point when I tried to adjust my fuel mixture screw. The screw was stuck in one position and wouldn't turn at all (using finger force). So I decided to attack it with WD40 from the bottom and through the tiny passage in the throttle body. I let it sit for some time and finally the screw let go and I was able to back it out for about half a turn. Then it got stuck again and I said to myself "jeez it can't be good". At this point after good amount of "finagling" I decided to remove it using pliers. So I slowly removed it. Lo and behold the thread closest to the tip of the screw had been bent and filled with aluminum thread from the carb body. I tried removing it from the screw thread and put the screw back in but it wouldn't go. Nonetheless, I was able to install the stock fuel screw with no problems at all and it looks like I am stuck using it for now. Here is some points that I want to make before anyone says anything: 1. The Kientech screw was installed about 2 years ago. 2. The Kientech screw was installed properly (no cross threading). 3. It was finger tightened and then backed out. Did anyone ever come across a similar problem with Kientech screw? I will be contacting manufacturer for sure to see what they have to say.. Now to the jetting question: the tip of the stock fuel screw and of the Kientech screw look very much the same. Should I follow the same jetting instructions for the stock screw as for the Kientech extended? If not can anyone provide correct settings equal to Kientech 2.5 turns out and 2.75 turns out?
