First:  We would have to know if Mr. lytnin has decided for sure that he wants to sell the bike.  Maybe he wants to try CycleTrader or use it as a dealer trade-in. 
NADA was a good source for bike values in the past I can’t find them on the internet anymore. 
JD Power suggests $5,360 for average retail value and $11,699 for a brand new bike which this probably almost is.  
Kelley Blue Book suggests $5,580 for average miles.  This one has extremely low miles.  I’d like to know the source and mileage of the engine replacement.
Second and equally important:  WOW Thank you Vic for making the kind suggestion and generous offer!  All I can say is if you guys help me out on this, I promise you renewed and robust activity on the forum including continued illustrated tutorials.  
Third:  I could use financial help on this (assuming lytnin wants to sell) but to be completely open, I have about $14,000 in my savings account.  I saved that while I was teaching for four years and I’ve maintained it with my parts delivery job I’m doing right now.  I could pay for the bike myself but there’s other possible needs and pursuits in my future that take priority.  I might buy computer and photography equipment, make purchases for a business I’m speculating on, heck I might even go and buy those carbon fiber wheels for the busa and new parts for the 14.  I’d like to buy a brand new Gen2 14R someday.  If I can do those things, I can buy or build another Rook bike if I really need to.  You know the passion I have outweighs the luxury of owning a bike but it’s still a luxury from a financial aspect.  …one I’d be grateful for any help in attaining but to be perfectly clear, the bike isn’t a need.
Vic, you’re as straight up as it gets ma brother!  The money would mean a lot to me but the fact you offered this help means lots more to me.  Thanks.
So what’s Mr. lytnin got to say about this?  St Louis is a long drive but I have the setup to come down there and haul your baby back safely.
