stage 2 jetting
#11
The reason I removed the air box assembly is due to the snorkle collasping under load and restricting air flow. Knuts said that the direct K&N gives a 3hp increase, thats huge! (on a small motor) Is the acc. pump necessary I know 400EX's have them no there carbs but if it's hard to dial in thats just what I need! All kidding aside if thats what I need I'll get it, but I'd rather get the carb dialed in w/o it. I guess i'll try fatting up the needle.
JSsDS,
When I went to set the jetting, I used the old plugs to get the motor warm and then put new plugs in to get a fresh reading. All my connections are good as far as I can tell.
One other thing, when I took it out, my tach was acting up it read well at low rpm, but after 4g's it went wild so I took it off. My last ride I got water in it. I'm assuming it is water damage, but thats off the subject. (I think)

I hope it's not the coil or the box! The coils look hard to get to and the CDI was $$$$. [img]i/expressions/face-icon-small-sad.gif[/img]
I still belive it's jetting related, because it was fine before I did the work. I'm thinking on the positive side.[img]i/expressions/face-icon-small-wink.gif[/img]

Double check both connections to the coils. Anytime you remove those connections, before re-connecting, you should close up the "connector jaws" a little bit to ensure a very tight fit.
How much water did you get on the tach? I have sprayed the back of mine with water before and it survived, although I try to avoid doing that.
Swapping known good components is a good idea to eliminate possibilities. FYI, I rotate my CDI box 180 degrees so that the wiring harness hangs down near the valve cover where I can reach it easily. Now I can swap CDI boxes quicker/easier.
