    Top-End engine rebuilds

    Does anyone know when a 4-stroke motor needs to be have a Top-End rebuild?

    I know several guys told me that they rebuild the top ends on 2 strokes about every 100-150 hrs after racing them!

    I havent heard of anyone having to rebuild one yet. I think Thomas has well over 200 hours on his skis.

    i've seen a couple that needed rebuilds.... luckily a unit under warranty 9 times outta 10 will get you a whole new motor... but the units that were tired and kinda maxed out in spec were units that were horribly neglected, beat on, and ridden in salt water and stores in water on jet dock and had over 100 hours on them..... but that says alot what i jstu said, was mostly neglected units that were just filthy and uncared for.
