I just bought a 07 WR450 and it came with a rekluse auto clutch installed. I don't really like ithe rekluse so i am going to change back to the stock clutch. I have all the parts I need except for the center clutch nut Part no 90170-20327-00. I've called all of my yamaha dealers in my local area and none of them have it in stock. Would it be a bad idea to use the nut that comes with the rekluse clutch with the stock setup?
