We just fiised rplacing the top end on a 85 cr 250. After we put it back together it started dit up in like two kicks. However when we rode it for the first time there was like no power. As the engine warmed up it gained some power but not what it had. Once it was hot for a while we pushed more but there was still not as much power as there used to be. What can be the problem???
