I am about to buy a Honda 300EX big bore 396..and the pistons seals and gaskets and everything like that are just put on it with 0 hours...he doest ride the 396 anymore cuz he got a yz...but I was wondering how many years it would be until I would have to rebuild the gaskets pistons o-ring oil seals and that kind of stuff..I was looking at the stuff and it only would cost a bout $150 each rebuild..I was just wondering how often I have to rebuild..I was thinking every 3-5 years..Im not going to be racing just trai riding and riding some trails and tram roads around the camp in Potter County..

 

Cant someone here help me with this...how long do you think it will be until I have to rebuild with the 396 kit? Im not going to be racing but trail riding and riding some trails and tram roads around the camp in Potter County..Come on guys...PLEASE
