i wanted to no if a 400ex carb will be ok on my 300ex but its not bored it got a cobra exhuast system and its got a stock carb jettted stage 2 with k&n air filter and i want to no if it would be good idea to swap the carbs but no jetting the 400ex carb????
true no i was wondering what there runing in the 400ex carb on a 300ex they say u have to rejet just trying to figer out what i would need they gave a forum but that just tells me about smaller and bigger jet i just wanted to know the numbers i need thanks tho
Well If I'm correct the stock jet on a 300ex would be somewhere around 120 for altitudes below 3000 ft. a 400ex is around 138 to 140 below 3000ft. putting that carb on a lightly tuned 300 would be too much fuel.
