Rock the bike gently forward and back while shifting into fifth gear. Now push the bike forward while sitting on it and see if the rear tire turning will turn the motor. If not, your motor is stuck. If it turns, you have a kickstarter issue.
Many people never learned to depress the kickstarter down until you feel it engage before kicking it through. Kicking from the top slams the gear teeth together and causes damage. You may need to pull of the engine cover to determine if there’s damage.

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.

how do i adjust the valves in my 2006 dr-z 125 sizuki

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

Yes it is possible to make it work,he has to dis assemble carb slide anyway,so while it is apart he can try it,should work though,doesnt hurt to give it a try.

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.

the intake is set at .004 and ex is .006

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 .

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

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

Have you held the bike up off the kick stand and checked the sight glass ?

Behind the radiator on the left side. It is the device with cooling fins, even though the electronic parts are embedded in rubber paste.The location isn't ideal and sudden defects leave people stranded so what people do is relocate the regulator/rectifier to a cooler place. Perhaps to the air inlet, under the air filter. Follow the three, mostly, yellow cables that originate from the stator when you don't find it behind the radiator.
