Review on XMMT Motorcycle CNC Engine Derby Cover/Timing Cover Compatible For Harley Dyna Softail Fat Boy Touring Road King Electra Glide Street Glide 1999-2013 by Trae Joubert

So there is good and bad. Thankfully, this is actually a pretty decent set of suitcases at a great price. The Derby cap comes with its own o-ring seal which is thicker than stock. The bad thing is that there are clots or burrs left on the timing cover from the machining process that have not been cleaned. Easily repairable with high grit sandpaper, but care must be taken in manufacture. The second bad thing that is really specific to the Barnett lockup clutch (as seen in the picture) I have in my FXLRS but the cap does NOT have the same internal play as a standard derby cap. If you don't use a lock-up clutch, the backlash isn't a problem.
