Lots of techs are taught to install bolt and screw with the head up so if the nut does work its way loose the bolt will stay in the hole and not fall out. Aesthetically, I would personally install it screw side down and put some blue lock-tight on it.That's what the instructions say. I followed the youtube video and installed it the way you did at first.
Hi Tim,awesome looking R1
Is that the $885.00 rear seat cowl and the $94.00 rear seat cowl pad?
The one you have attached in your post is off of the "M" which is the carbon fiber cowl. The one I installed is the Yamaha Genuine Accessory seat cowl which was $275.00.
Gravity sucks! LOL .... Aviation maintenance requires bolt heads to be installed heads up or facing forward so bolts, pins,etc. won't fall out as easily if the locking hardware vibrates loose and should fall out. Cotter pins, safety wire, etc...are used on all critical parts whenever possible. Most Racing techs are taught that too!... Becomes a habit. I wouldn't call a license plate bracket exactly critical so just use a little locktite and install it any way you want and call it good! Like I said it becomes a habit, but it's a good one!What????????
