We had this happen last weekend. Two short rides and the bikes had a lost a cly. And the guy bought it from his son the day before going down. It's just the shitty luck of it.
I had a ss ported white knuckle motor from around 09-10. really wish I would have kept that motor. Fun bike, it was really rider freindly, till we put a stock swing arm on it, then it was a hand full!
Anytime I have sent my motor out or had any work done to any bike I alway get that call saying hey I notice blah is worn and should be replaced or while I am here do you want blah blah done. And can trust that there not screwing me that it does need it or could use it and should be done.
One big down fall is the hubs won't fit stock axle. You bend a lsr or durablue that take all stock hub you can probably find a replacement somewhere on Craigslist in Oregon and salvage a weekend. That being said I plan on getting a jj&a and abusing it. 10lbs difference from a lsr is a lot. And if there warranty are that good chances are they don't warrenty that many.
