View Full Version : 250x/300ex jetting



02-14-2002, 09:28 AM
I have a 1987 250x that I am about to hop-up with the following parts for the upcoming riding season.

I will be using a UNI filter, modified airbox lid, and a Supertrapp IDS 2 head pipe and silencer system. What would you guys recommend for jets in the carb? Or, do you think I should spend the $50 and get the jet kit from K&N? I was hoping that I could just change the jets without buying the entire kit.

The places I ride vary in altitudes from 500 to 1500 feet above sea level.

Any help would be appreciated.

Don't waste 50 bucks. Go to Cycle City and buy yourself a 128 a 132 and a 135 main jet. They cost 4 bucks a piece. You can change them on the quad without too much trouble.

I agree with countypark.There is no use in spending 50 or 60 bucks for jets.Go to cycle city.

(Just a second opinion)
