How many hours before changing piston

Recommended Posts

If ridden pretty hard, but not constantly bouncing the rev-limiter, about how many hours can I put on a crf250 before I need to change the piston?

When did you do your first change?

the book call for every 25 hr. I have about 138 hours on mine and just pull the head and jug, the valves and head is getting ported and a vavle job and the piston is about due

PS I ride this thing like, I'm running from my X wife all the time :thumbsup:

<font color="pink"> I have a 250r and the manual calls for a piston change every 15 hours..but the guy at honda said to change it once every season unless you doing some hard core racing ... i bought my bike in the beginning of august and im gonna redo the top end in april before i start racing...i guess its good becasue i dont too too much riding over the winter anyway....as for the valves im going to check them after my next ride and then from there on out its recommended that you re-inspect them every rebuild
