Ok so im going for it. Im gunna do my first bottom end. There must have been a reason that it wouldnt go into 5th. Even though its working good now im still gunna do it. Besides i bought another 08 yz450 so i can ride one while working on the other. I looked on ebay at bottom end kits. They got wiseco and hot rods. Witch one is the best. Or should i go oem. Also i was lookin at case splitters witch one should i get. Theres a cheep one for 57 bucks and a motion pro for 159 bucks. Or should i look somewhere else? Help me out here guys.
