i jetted my 300ex according to dynojet. i have an aftermarket exhaust and i am runnin no airbox lid. and when i give it gas like half way it jus boggs down. and it gets worst in higher gear. i need help or wut am i doing wrong asap. thanks

Odds are that it is running to rich. If it bogs when you hit the throttle then chances are it is getting to much gas into the engine. Try putting in a smaller jet. But that is just if you changed the main jet, if you did other things, then it might be something else.

i changed my main jet, and moved the needle.

[hondardr4life]

How many notches up or down did you move the needle and what kinda mod did you put on to require a jetting change?

[JRP]

i moved the e clip down 4 notches on my needle. i put on an fmf megammax 2 exhaust.

[hondardr4life]

Moving the needle down, if im correct i might have it backwards, will make it more rich. Also, what size main jet did you put in.

[JRP]

im rele not 2 sure wut size i put in. it jus came with my quad works preformance. there were liek 10 main jets and each bag had numbers.and the number i used was 124. it said so on the directions 4 the jet kit.

[hondardr4life]

Well, i dunno what brand of jets they are but if they are kehin, the stock jet size is 122, so I would say to maybe get a 126 and move the needle back up those 4 notches. The problem with jetting is that you have to experimant to get it right.
