Question about Suzuki DR-Z 250 Motorcycles
1994 Suzuki dr250ES, starts and idles ok, rides well but if you throttle on under load it coughs and splutters. Carby pulled apart and cleaned, tank cleaned - could it be the coil?
Possibly but from you description I would be looking at a condenser failure ( not allowing full charge for the coil)

carbs need a good cleaning. had this same problem with an 82 GS1100. cleaned the tank as best i could, you can never get all the rust tho. finally had an idea to place a couple of old car speaker magnets on the outside bottom of the tank to catch any residual rust. been 4 years now with no more problem.

Sounds like water in the gas.
ALWAYS have a fire extinguisher on hand when working on carburetors.
For each carb > Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. If the bike doesn't start and run properly then shut off the gas and remove the carburetor from the engine.
Remove the float bowl and clean the entire carb with a spray carb cleaner from the auto parts store. Wear protective goggles to avoid getting spray in your eyes. Spray into all the little airways and fittings in the carb. Put the carb back together, clean the air filter and install the carb. Let the float bowl fill then start the engine. This process should get you back on the road.
Please rate this solution. Thanks!

big spring is for the dighram! the only other wouls be for the pointy mixture screw
wind the screw in till it just stops [not hard]
then wind out about 1 & 3/4 turns that should be a close air fuel mix then adjust idle & mix till you get it right
