I'm going to start at the stock settings for my year carb (90 to 93), which are very close to how Danger's carb is set up.  I still plan on doing some plug chops just to make sure everything is okay and not too lean.  As much work as I have put into this thing, I don't want to screw it up now.   It's just now starting to get  fun to ride.  :-)
Perhaps I have a dirt bike addiction?

just remember to go small steps at a time....and only change one thing at a time.

Only issue u might have is  the carb could be worn
a few links i found a good little Graph on Top Corner on how the needle is tuned

IT amazes me how small the pilot get on later years with same motor

The range of jets suprised me as well.  The sizes are all over the place as the years change.  That's a good point about the carb being worn out. If the different jets don't help, I will probably look into buying a complete carb from Sandblaster.

I've read some good things about them on here.  Is there a good place to buy them, or do you buy directly from Lectron?

Ok, umberto, I can't call it the parts bike any more.
Stuck the carburetor back on, cleaned the tank
put everything back together and started on the
4th kick. Tomorrow after a complete fluid change
I'll give it a test run.  I'll call this one Danger4u-also.
It's not as smoky as the camera picked up.
My boss is so cool, we have no work but I still get
to use her shop and equipment.  I know most of you
don't want to hear this but I'm ready for gasoline to go up.

That's awesome!  That bike is in too good a shape not to run. Watch out Lake Draper, here we come!

i noticed something weird today, i started the bike (first kick very nice) and it slowly kept reving up as the engine was getting warmer, when the engine was hot it kept going up and down i tried screwing the idle screw out a few turns without success, after a short ride, the bike wouldnt idle at all :? any ideas?

possible air leak...
possible dirt/debris in the carb/bowl....

i recently had the carb out to change the jets, could this be the reason there might be air in the carb and thus why it wont idle since i turned the idle screw to far out?

very possible...which way did you go with the jetting, richer or leaner?....and which jets did you change?
