I have a 2003 ktm pro senior lc for my son, the bike was running good until the water pump did a seal, I have replaced the bearing and seals, but now the bike has no power. It will start and run well on the stand but once he gets on the bike and tries to ride it , it barely moves just revs up and won’t move, any ideas guys?? Would be greatly appreciated.

It sounds like he is running out of fuel in the bowl,poss accelarator pump ?

SOURCE: will not run

Remove the water trap bowl at the bottom of the petcock, (gas valve). Any water or trash in the bowl? Drain a cup of gas from the tank. Any water or trash in the cup? Dump it, clean it and re-mount it, ( not all bikes have a water trap bowl ).

Drain the carburetor. There may be a screw on the lower side 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. Install a new stock NGK spark plug and try to start the engine. 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. Remove the two screws on the outside throat of the carb and spray into the screw holes as well.

Be sure to put these two screws back in the same hole they came out of. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Put the rest of the carb back together, clean the air filter and install the carb. Be sure the bolts are tight. Let the float bowl fill then start the engine. Set the idle speed with the idle screw, (sticks out from side of carb perpendicular to the carb throat).

If you are smoking that badly, loose the gas in the tank and start fresh with a 32/1 gas/oil mix. That equals 4 ounces of TWO STROKE OIL to one gallon of gas. Do NOT use motor oil in the gas. It may continue to smoke for awhile, until it rids it'self of built up oil in the crankcase.

On the clutch, be sure the oil level in the gearbox is correct. This is where 10w40 motor oil goes. Check the clutch cable linkages. One at the clutch lever and possibly one at the motor. You should have about 1/4" play in the clutch handle before the lever starts actually pulling the clutch.

Look into your power valve. If it doesn't operate freely, you won't get peak performance. They can get gummed up.
