i herd your supposed to change the rings on your 450 every 30 hours of riding im thinking about buying one but i wont if thats true any of you guys had to change your rings and if so after how long

 

didnt you make this same thread like an hour ago and get an answer

 

no u dont thats if u race it, i have put over 2000 miles on mine in a year and the only reason im about to rebuild it is b/c some dirt got into my motor, thanks to the air boot falling off

 

I got my YFZ on 7-9-03.... I ride almost every weekend i havent had to rebuild it yet....Still runs great, doesnt use any oil....I do take very good care of the air filter though. I think that will extend the life of any motor...[img]i/expressions/face-icon-small-smile.gif[/img]

 

I have put around 40-60hrs on mine and i havent had to rebuild it yet.. Just keep you air filter clean and the rings should lost a long time.. Unless you race it alot.

 

i have never heard that
