Have you ever looked at a part and not been 100% sure you whether or not you should run it? Are those cam cover bushings a little too worn out?  What about that long oil pump bushing in my case?  I definitely don't want to change that one if I can help it.  Is my cam bearing out of spec? 


Say you have a Sportster cam cover and all the bushings seem a little worn... but you don't have a dial bore gauge that will go that small... plus there are several bushings to measure... Do you just kind of stick a cam in there and see if it wiggles?   Do you just keep running the same cam cover with the same bushings? 


This new and essential innovation from Fast Eddy Co. draws a line in the sand and allows you to be 100% certain that your bushings and bearings are within their service wear limits.  Don't just guess.  Be sure it's done right and that it's going to work for a long time.
