I passed out,
took a little nap.
Went out and took pictures and a one minute video of
the beast and it's symptoms.
now the plug looks black, it loads up like it is too rich,
yet still dies at full throttle.
should I post pics and vieo here?
I could make a youtube video and post a link here.
thank you everyone.

The video won't load on youtube.
Maybe I should ride it like it is.

Raw Dog...

How does it idle.... fine?

If so then maybe your main jet needle is seated high? What is the main jet on that thing? There is a number on it... that is the size.

Think those things are like #68. What position is the main jet needle? If you are sealed up with clean oiled filter - then maybe you are up to high on the main jet needle (typically they should be in the middle of needle grooves - verify in the service manual)?

Did you download the service manual - it a great tool every spree wrencher should have.

I had a condition like yours where someone was over compensating for a blocked pilot... and jacked the main needle. I cleaned the pilot and put the needle back to the correct position - now it runs like a champ.

For grins what is your compression number... birthday boy Path would typically suggest that folks have shinny cylinder - just needing a cylinder hone.

Does it bog on the center stand at WOT... if it does not, then it would point to a compression issue.

Best of luck... report back.

That needle will get you like that for sure. I agree if it starts and idles fine it proib ain't the pilot now. Its probably a given that it has what I have now named "Shiny Bore Syndrome" but I suspect something else is the issue causing it die unless its been soft seizeing. Usually "SBS" shows up as runs fine until it gets hot on a long ride and the take off just starts to get worse and worse.

I dunno the jet size, even with these reading glasses. The jet has to be screwed in as far as it will go as it holds that brass tube with holes in it, in place. It will rev up and die on the kickstand with the wheel spinning on riding it with a load on it.
I am at a loss.

[patthesoundguy]

You will likely burn it up if you ride it like that. If its as lean as it sounds a melted piston on will be the result. Put it on the stand get it to idle and put your fingers partially over the intake holes of the air box as you try to rev it up. Vary how much you choke it as you rev it. If you get it to rev up that way its lean somewhere. It may be easier to pull the hose off of the carb to do it, not every one can reach under on the air box and rev at the same time. Where there is no manual choke this is an easy way to richen things up.

Dude swap in a dio

[rawhead]

Good idea!
Hand choking it will tell if the bowl is emptying out or not as well. Yeah, I do not want to seize it.

Dio motor? Same carb,on them?

[patthesoundguy]

No the dio carb won't really fit I've been told, the by starter doesn't clear the shock. And he didn't mean swap in a dio carb from a dio, he meant swap in a while dio motor :-\ from a trouble shooting point of view that isn't the best idea, what if the new motor has more issues than the spree motor does in the first place.

This morning I am borrowing
The neighbor's chinese 150cc
to run errands.
It is an xing brand.
I get to ride it whenever I want because I work
On it. Amazing how much goes wrong with it when it is
Only two years old.
I really want to ride my Honda.
