1999 yz 400 lifters???

rebuilding a 1999 yz 400 that dropped a valve, got the engine in pieces when i bought it, ordered all parts needed to rebuild it but they asked what colour lifters i need??? said theres 3 kinds yellow black and green read the whole manual and it doesnt say anything about different lifters???

If you can make out the paint marks in the head adjacent to each bore, the ideal thing is to get a match for each one. The color, though, can become indistinct over time. If you either can't determine which ones it has, or the alternatives are not available, order the black ones.
