Title says it all I guess.

P.S. how many do you have on the bottom end?

0.9 on the KX125- just did the top end. New rings/piston at 20 hrs of play racing.

2 or so on the KDX200- ditto. New rings/piston every other year.

Dunno on the KTM200sx- just got it. Will re-ring later this fall after I sell the KX and KDX.

Never touched the bottom on any of these bikes.

I only record liters of fuel, of which about 300 for the top end and the same on the bottom(new bike). With my slow riding, this is about 45 hours probably.

I'm planning to do the top end right now and I hope to sell the bike before I have to touch the bottom end(maybe 200 hours).
