I need about $1100 worth of parts (Including the right-side case) to repair the bottom end of my bike. While browsing on EBay I came across a shop selling a complete '03 bottom end. I asked them if I could replace my bottom end with theirs and they said "yes" and that all the parts are interchangeable. Since they're obviously motivated to sell their engine and probably don't care about whether I get to ride or not, I thought I should check it out first before I dump my wallet. Anybody know if their claim is true?
