Just wondering, can this be done easily? Does anybody do this mod?

Seems like one less thing to fail, and the last thing I want is problems with my new to me dream bike....

Also, if one did need to do a bottom end rebuild (I've got the top end rebuild kit on order, OEM honda pistons and parts...Just in case...) where would you source a crankshaft from? Seems almost impossible to find one..

..On another note I got some time today to work on the bike. Found it hadn't yet been derestricted (awesome!) so I'm going ahead with that.. Also setting the RC valve like you guys said. Seems like she'll be gaining a few HP and running better than ever!
