I just got the son a new 2004 cr250 that was old stock,, i have purchsed a vforce 3 reed block and a r304 shorty silencer and we are at near sea level but in australia,, was just wondering a base line to what to jet it at and i run 96-98 octane fuel with motul 800 at 32-1,, we havnt put any of the parts on it yet but he is complaining of it being very boggy then a hard hit of power but i havnt even changed any jet settings yet and he still is going hard on it in racing,
Thanks again
