2001 Foreman 450 ES hits rev limiter at half throttle

[Adamsmopar 0]

I have a 2001 Honda Foreman trx450es runs great rebuilt the carburetor factory carburetor still cuts out on me like it's hitting the rev limiter replace it with the aftermarket carburetor does the same thing had somebody look at the factory carburetor put it back on it but it hits a rev limiter about half throttle, fires up just fine but is there an issue with my CDI box?

i am having the same issue and find if i put the lights on it will rev up.

Check voltage regulator output at battery while running at half throttle, it could be overcharging and the load, ie lights etc, is bringing it back down

should be no more than 14.5-ish at half throttle 

Most times when I see one that wont rev out, its the CV carburetor boot is pinched/not sealed under top cover or the  timing is off one cam tooth

Yours is definitely electrical if it revs out with additional electrical load

Definitely check out battery and voltage regulator condition
