Check your fuel supply.

You probably cannot ... It takes special tools and expertise to properly balance a motorcycle carb. If you think it is the carb, take it to the dealer for a tuneup.

You will be busy installing a new oil seal as the water pressure has blown the seal. A gearbox set up will help.

Your motorcycle is equipped with a wet clutch . The engine, clutch, and the transmission all run in the same oil. Use any oil that is JASO MA certified motorcycle oil. 10w-40 for cold climate. 20w-50 for warm climate/touring. Car oils use different additives and may cause scoring in certain types of cam bearings. Do not use any oil that says " Energy Conserving " on the label . It will shorten the life of your wet clutch and transmission gears. If you choose Synthetic oils, they will help your bike run cooler and shift easier.

Also a four-stroke has the tendency to tick somewhat unlike the 2-stroke. If it seems too noisy or the ticking is more like a rattle have someone check your valves.

It sounds like you have to take your carb apart and clean it or you will possibly need to rebuild it.
Make sure your air cleaner is clean.

Throttle cable needs oiling ,Up for choke on .

2003 Suzuki DR-Z... | Answered on Mar 20, 2010


There isn't necessarily an adjustment on all bikes. You can drop the ride height by adjusting the tension on the spring on the rear shock and lower the front end by moving the forks up in the clamps on most makes and models.

Take the Carbeurator apart as much as possible. After that spray carb. cleaner in all the little holes that carries gas. I did it on my yz-125 and found a grass-hopper leg that kept over flowing the carb. Also make sure your throttle cable is good

2003 Suzuki DR-Z... | Answered on Nov 15, 2009


or you looking for the idle screw or a screw to keep someone from opening the throttle the whole way?
I the idle screw is located on the carb, as for a " stop screw " if it has one it should be one the throttle housing. if it does not have one you can order one from world of powersports.
if you need more help feel free to contact me
