Question about 2007 Suzuki DR-Z 400 SM

1 Answer

Wont rev up, just makes a noise like a tractor

Sounds like carb freeze, wont rev up, just makes a lot of noise. its not carb freeze, have taken carb off and checked it over and everything is ok. taken the head off to see if the cam chain is causing the problem, but its not its fine. the bike is also very hot after about 2 minutes of running, can not hold hand behind exhaust because its burns after 2 minutes.
think now it maybe the cdi unit under the seat.
hope somebody can help

My jd 111lawn tractor wont start was mowing it just slowly died.now it will turn over but wont start


Sounds like a fuel issue. Check and make sure your gas tank has fuel in it. Then check fuel filter to see if it is allowing fuel to the carb.

Try looking at the Governor on the engine. You can usually adjust this out at the Gov arm by loosening and tightening back when smooth. Could also still be dirt in the jets. Make sure all the small holes on he carb are clear and check the float height too.

Starts on choke but won't rev and stops when trying to rev or choke off


It sounds like either the jets in the carb are plugged or the slide diaphragm in the carb has a hole in it. First take the air filter cover and air filter off the carb. Start the engine with the "choke". Do not get your face too close to the carb but look into the carb and gently rev the engine. The slide should move up and down. If so, the diaphragm is probably alright. If the bike has been sitting up for a good while, the gasoline in the float bowl would have evaporated and left behind a thick gummy residue. This may have the main and slow speed jets plugged up. The carb will have to be taken off the engine and professionally cleaned.

Good Luck

Why does my lawn tractor tractor rev way up when the throttle is on slow and the choke is off?


that could be caused by a sticky float valve--remove the bottom of the carb and make sure the float valve moves up and down very freely

Runs very poorly on occasion when cold. It smokes, sputters and makes popping noises. Seems like it wont warm up. Temperatures usually in the teens and 20's when this occurs.


popping noises are most caused bij lean burn. make sure that there comes enough fuel to the carburator, most of the times there is water or dirt in the carb. clean and blow with airgun special the litttle fuel restrictors. good luck

sounds like your carb could be blocked with dirt if it wont start unless you put juice down plug i would take the carb off and give it a good clean and also make sure the jets ok just clean them with carb cleaner and a paper clip

Wont start sounds like it's getting no spark and starter makes noise.


check the compression and timeing it is easy that the during the lay down the coiles and resistor could have shifted just a little and through off the timeing.

Engine loses revs on tickover and makes a stange clicking noise.


Could be a carburation problem, or could be one of the many ignition/carb control devices faulty, a workshop manual would guide you through the separate continuity tests for the separate components. |You would need to be able to use a circuit tester! The noise you hear maybe nothing but sommit thats become more audible to you because the general noise has dropped, but sounds to me like a fault on an electrical component on the carb.
