Wendys has gotten loud now too, I hope it is just out of adjustment as it's time to do the job. Mine is loud too but I never thought of the cam or head being worn. Sounds normal to me but now I'm going to have to go look at both bikes. I have said for the day I found out they didn't have cam bearing that I wish they did and thought it was a bad idea not to for just such a reason or future rebuilding.

I learned all I need to know about life by killing smart people and eating their brains.
