Help with 93 KDX 200

[horakn]

Hi,

I bought a 93 KDX 200 about 2 weeks ago. It's in good condition and going BUT it has no power at all. I cleaned the carburetor, new air filter, new spark plug. New gearbox oil. i also cleaned the petrol tank.

When i open the throttle the bike goes but as soon as i open the throttle a bit more the bike just stops.

Can anyone help or maybe let me know where i can get this fixed or maybe help me with a workshop manual for the 93 KDX 200?

Thanks

How smokey is it ?

What condition is the plug in after running ? wet, oily or what ?

how wet is the muffler ? does it need a decoke.

It's smokes allot and when i took the old plug out it looked like there were some oil on it.

what do you mean with "decoke"?

PS.. i must be honest to say i'm new to bike fixing, so any help will be good :-)

If it's smoking alot there's a few possibilities but depends on what colour the smoke is.
Here's a plug chart to compare the plug with

if it is oily then it's possibly rings, but if its just fuel wet then it means your running too rich.

Decoke; Over a period of time carbon & unburnt fuel deposits collect in the exhaust and choke the flow of the pipe & cause loss of performance, a decoke is just the removal of these deposits

Did you remove the main jet when cleaning out the carb?
Maybe you didn't put it back in again. That would cause it to go way rich when you open the throttle.

WOW thanks for all the info. never thought i will get this response :-)

i think i know the answer. I MUST TAKE IT SO SOMEONE THAT KNOW BIKES :-)

Is there anyone that could guide me to where i can go or even help me fix it?

You did remember the needle? And it's properly clipped?

Where are you in Auckland?

If you are on the shore, go to Spectrum, just off barrys point road.

Not that I'm an expert or anything... but I recall my brother having probs wit the power valve on his KDX (side of the head) and I cooked the piston in an older yz250 and it ran like you explained... with a big hole in the piston...
wanna swap for an 82' xr200
