Wha??? Don't mean anything buy it man. Just a "tip". You know when you txt your friend or Chat IM that's one thing but, when you need to be descriptive and writing an explanation of things, than being clear is important.

I'm not pointing fingers. Just trying to be helpful. : (

 

I know what you mean Koopa. Some of the questions are very hard to figure out because of extremely poor grammer. Incidentally, you have many grammatical errors yourself, but at least I know what you're saying.

You used "no" but should have used "know".
You used "buy" but should have used "by".
You used "than" but should have used "then".
You spelled Wha instead of What.
You spelled you instead of your.
You missed numerous commas.

Should I stop now? lol. Just razzin you, man. But seriously, yes, I know exactly what you mean. It's very hard to answer a question like this:

I have a 400ex that has a axel problem with it that turns but not always sometimes and if i kan get it it will not fix to be has anyone heard of this.

Are you running the air box lid on or off? Also what size and brand of jets are you running ? thanks</end quote></div>

Front of the airbox lid is clipped down but at the back of the box turn the clips into the box and let the lid rest on them, then snp the side clips on. This opens the back of the airbox lid by about a quarter to half an inch.
I use Keihin hex jets.

I don't remeber what size jets but it was what HMF recommended.

Sorry, double post, don't know how that happened.

Haha, oh ya man I am horrid with English. It was my weakest point in high school, lowest score on my ACT and was a killer all the way through College.
Glad you get my point. Hope I didn't offend ol' BlackCloud to bad. I really didn't mean to sound cocky.

Anyway, my setup was a lil' diff than Red400EXRod. I had dynojet's with lid off. I still never touched the that screw. 3 turns out on idle screw worked. Also helped on bro's ex and best friends. Never touch screw on any of them.
