This was in fact the first SE 117 Drop on that I'm aware of on this site, Steve posted about the build on this site. It is a purpose build from the top down with S&S wheels, pump & plate, upgraded comp & compensaver, GMR heads and Steve's 600 cam & Baker DD7. It appears the front drive pulley locking nut backed off at speed and sent a piece of shrapnel through the top of the inner primary cover. No definitive answer as to why it took 3000 miles to happen! One would think that if not torqued correctly it would have let go on the dyno or with in a short time frame soon after, I don't do burn outs or launch it from red lights but I do ride harder than most of the guys I ride with & have fun with it from time to time hard not to! Had mechanic tear it down to diagnose and document, I called and talked with Steve & sent him some pics Steve talked with my shop then called me the next day and informed me he was covering the repair.

That makes Steve a stand up guy in my book!!!
This all transpired approximately 7pm on a Sunday down on Cape Cod after a trip to Connecticut earlier that day! I sent my mechanic a text stating I would be bringing my RG to him in the morning and that i was broken down on Cape Cod, He called me within minuets and said he was leaving New Hampshire with a broken bike in his trailer heading back to his shop & that he would pick up my Fat Bob which he just finished completing the tune and fluid changes and bring it to me and grab the RG so I can have a bike to ride home!! A big shout out to Rob Swartch of Robs Dyno Service, Customer service at it's best.
