Hi I have a 1991 trx250x that starts up fast and rides good but I'm having a issue at top speed. It gets there and drives good but after a few seconds it starts to stall but if you let go of the throttle it doesn't die but if you hold it the atv will stall and day. Any advice? Its stock but has a white brothers exhaust on it.

 

How long has it sat. It might need the carb cleaned and a new air filter

 

It hasn't been sitting I run it every week or every other week for a good while, I do the oil changes on time and the air filter was changed recent. Also I had someone rebuild and clean the carb, I changed the spark plug, cdi, and the ignition coil (I believe that's what it's called)

 

what do u have the carb adjusted to? could be that i had a 300ex did that all the time i adjusted it and it was fine

 

may need float set to allow more fuel in bowl.. hope this is helpful
