I need some big help in finding a part, it's the same in all '06 big YZ's 125-450F 1C3-2316A-N0-00 .VALVE COMP. I had a shop do some work for me a couple of months ago and they funked up the part....the plastic pressure spring holder which is part of item number 12 http://parts.yamaha-motor.com/partimage.gifx?d=84063,2,0 . I have the part on order, but its due date is Oct 5, on backorder...after GMB. So are there any Yamaha dealers on this board that may have a donor bike sitting on the showroom floor or any ideas? I would replace the part with a new one once mine shows up.
