Dies on bumps

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?

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!

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.
