I have a tecate 4, which is running extremely rich. I have a Trinity pipe, bored-out and boyesen pro reeds in it. It runs really rich, even when i run it without the filter box attached to the back of the carb. The motor lacks throttle response. I'm running the stock jet (260). With the mods shouldn't i need a bigger jet? Could a weak stator cause this prob. Any help would be appreciated.
