I noticed my 2005 Mach Z was overreving a little and stopped to change the clicker and noticed a piece of one of the arms was broken off and laying in the bellypan. It broke where the set screws went in to hold the pins. I have adjustable pins and use the cotter pins, well 2 of the cotter pins were broken and one arm was broke. I noticed a few people were having this problem also. I think the cotter pins I used were too small and they didnt fit tight enough. Does anyone have a stock arm they are willing to part with? My local dealers do not stock them and they are a few days away. Im in the Albany, NY area if someone local has one they want to sell please PM me. Also any dealers not local that have one in stock and could overnight that would be great. I also need two washers that go with the roller.
