The thing that sucks is that I had like 4hrs on that top end and just bought new gaskets,then a head stud decides to come out of the cylinder causing me to get another set for when the cylinder was done being helicoiled. Once it was together my left pipe would vibrate, I grabbed the fly wheel and figured out the main bearing was going. I had keven herr weld a mint extra crank I had and bought new main bearings plus bought a cool head and was trying to sneak past changing those gaskets again haha sometimes it has to be a pain in the ass but when the banshee is running strong it more then makes up for the frustration. I used the yamabond 4 by the way and it wasn't rtacky in my opinion, I think it applied well and the curing time was on par with putting the clam back together. When I was rebuilding the bottom end I was thinking wow, this is so much better then rebuilding a 250 bottom end
