My 98 kdx 200 misses when getting into high revs, so it doesnt get to high revs at all, just misses and splutters, even when you in neutral and hold the throttle open just doesnt get to that constant revs, could it be the carb cause i have been having problems with the carb, like the carb flooding badly where your header pipe is full of petrol, please help

i would try to map the fuel system as it sounds like its totally out? ive never heard of it affecting it that much? also try replacing air filters.

The side stand kill switch can go bad and do this. Check the switch with an Ohm meter. Also, check the wiring harness connections. Fix any loose connections. Check the handlebar kill switch. It can go bad also.

Please rate this answer. Thanks hd87lovetori!

Use a hotter spark plug. They do have different heat ranges.

I had a similar problem. For the float needle there is a seat that it goes into, check this for dirt first, then if no dirt present, the brass part (not the needle but the part it seats into) has an o-ring where it mates to the carb body. If that o-ring is not tightly sealed it will allow fuel to bypass. I found o-rings very cheap at pep boys just take an old one with you to match for size. very cheap too. (under 5 dollars)

It gotta close the valve when the bowl is full. You can test by replacing the bowl in place and connecting the gas, if it does not overflow its good, it gotta let the gas enter the bowl till full and it will be correct. Its not a precision settings, just try and see...
