I need help with my 93 trx300ex, it runs pretty good until it gets wormed up and then no matter what gear I'm in it bog's down when I give it lots of gas and I don't have anything for power, I have to be very easy on the throttle so it runs good. is it a spark issue or what? PLEASE help Thanks
I was wondering the best jetting I should use for a stock Honda 300 ex for more power, I plan on getting better exhaust, but not for a while. I live in Washington state, elevation for the places I ride is around 500 to 1000 feet above see level.
