How do you check float height? The manual is a little brief.
I've checked and wiggled every wire I could get my hands on and found nothing. It has to be gas related. I checked bouancy on the float..it defintely floats and doesn't leak anything inside. Being all plastic, I would think it's not adjustable?
It HAS To Be Gas-Related

Greetings:
You are correct in that the float is non-adjustable. Honda-san's prescribed remedy for an out-of-spec float is to buy a new one.

I'm not convinced yet. Maybe it's in one of the wires you didn't/couldn't get hands on? There's some stuff behind the front cover and right side plastic too.
The carbs on these things are not very impact sensitive, unless it's a loose/stripped mounting. If you can reproduce the kill by * the carb, that may be it. The carb flange threads are prone to stripping if abused. Otherwise, I'd still rule out electrical. These intermittent faults are a leading cause of male-pattern baldness.
No bump-related float malfunctions have been reported before, AFAIK. If you mount a known-good carb from another bike and the symptom's unchanged, you will have your answer quickly.

You generally check a float by placing it in warm-hot water and looking carefully for air bubbles forming on the surface of the plastic. Any bubbles appearing form nowhere indicate a leak. Don't use really hot water though - you may pop it!

Update?

same thing happened to me yesterday. its raining right now or i would look into it but yeah, going down the road i hit a bump and it sputtered and died on me and wouldnt restart.
gas and oil were topped off, i doubt its a gas delivery problem.
i'll post when i get a minute or two to work on 'er.

Make sure that the plug cap is secure on the spark plug.

it is a short somewhere. I have seen scooters do that. check the coil and cdi connections, also check you stator connections. . You are grounding out somewhere. double check your ignition wires also.

well i finally had a chance to check out what my issue was; the spark plug had backed itself out of the cylinder, as well as the positive side ignition wire worked itself loose. fixed both and ta-da! ran again no problem.
as an aside, this is the second time in the few weeks i have owned it that the plug has backed itself out of the hole....once i get a new plug i'll have to loc-tite it in there.

Well, after putting a new needle and float in the carb, the thing still continues to die if you * it or bounce it. Anymore suggestions? I guess I'll keep checking the electrical.

Something's wrong if you have the plug backing out. You shouldn't have to use loc-tite, and in fact I would be fearful to use loc-tite. I suggest maybe you're not torquing the plug down enough.
I'd still (not?) rule out electrical. These intermittent faults are a leading cause of male-pattern baldness.
One of these days, Wheelman is going to honor us with a photo of that bald knob.

I'm with the ole baldy on this one. Although, there might be a vacuum line that is wiggling on bumps just enough to kill you. It's a long shot, but check for old and cracked vacuum line. Then go back to checking electrical.

Be careful about torquing a steel spark plug in an aluminum head. The threads will strip out of the head if you get ham handed. Use a torque wrench when in doubt but the torque setting for an aluminum head is 15 foot/pounds max. I would suspect that a plug that keeps coming loose has a over crushed washer. FYI, Loctite on a spark plug is a no-no.

There was a thread a while back called "Bumps cause Spreeicide" or something like that. You might find more info there as well.

did you play with the bystarter at all make sure it is working right i think that may have spmething to do with it if its not electrical
