You will need to slightly loosen the line where it goes into the master cylinder,...then squeeze the lever and hold it in...fluid should come out. While holding lever in,re-tighten bolt. You should get a lil bit of lever feel now. Making sure there is fluid in the resrvoir,...squeeze lever multiple times,and hold it in,....loosen the banjo bolt again,...slowly,..untill fluid rushes out. Then,..while holding lever in,retighten banjo bolt again. Check fluid,...then pump the lever multiple times again,and you should be getting some good lever feel now. After this,you may need to bleed the air out at the bleeder a couple times till alll the air is out.

You might have bent shifting forks or the dogs on the gears are worn. That would be a case split and Removal and Repair of bad parts.
TRY THIS FIRST:
Work on your shifting technique. When you want to shift from 1st to second apply up pressure with your toe and roll the throttle off and let it pop into gear. Don't use the clutch other than for starting or a few suituations where you need to idle while in gear. You might not be allowing the transmision to pull 2nd gear all the way in and it drops back to neutral.
Hope this helps.

Start in the middle. Check you spark plug it should be a nice cocoa brown color. If its stumbling and not running correctly then lower it 1 notch (This Raises the Needle alowing more fuel) if the plug is fouled and wet then your over fueling in the middle to high end so raise the circlip (Lowering the needle - reducing fuel) adjust accordingly using your spark plug color as the guage.
The Main Jet determines fuel mix at top speed and the needle fits into it's oriface regulating speed depending on throttle position. You may have to to up or down a size depending on you altitude.

Any easy way to bleed
With a vacuum type bleeder is the easiest & best way. They can be purchased at the auto parts store
Leaking transmission oil
Thank you for contacting FixYa with your inquiry.
We probably need a little more information on the year and model to provide exacting details of the parts involved.
In general clean the engine up real good and try to determine the source of the leak. It might be something as simple as a loose case bolt that just needs to be tightened.
Might be a gasket, O-Ring, or a seal. Most cases these are pretty easy to remove and replace. Sometimes gasket sealer or silicone gasket maker can be your best friend.
Search your bike info on the below fiche finder and it should help identify possible leak locations and related parts.

2005 ktm 125sx how to
The Magura hydraulic clutches on KTM's aren't really adjustable. If it's dragging a little when you put it into gear, there is still air in the system.The proper way to install the fluid is to fill it with a syringe from the bleeder screw until the reservior is full. This insures there is no air in the system. There are kits available aftermarket specifically for Magura hydraulic clutches that come with a syringe and a new line for around 30 dollars. It is a good idea to change the fluid and line every couple of seasons.

If the carbs are the same inlet and outlet size and you swap the jets, it should work fine
Lowering seat height
you can lower the seat height by adjusting the rear shock preload decreased the pre load and it will lower the seat height atleast by an inch or two...
My bike throttle is cutting
Your bike has a rev limiter on it when it reaches a certain level it starts cutting out to save the motor from blowing up

You will need to bleed the system. This occurs after long periods of sitting.
Leaking behind the front sprocket..
Yes changing that seal is going to require thus splitting the cases. So if you have the time and tools it is maybe two weekend project. As for how long a mechanic is going to take, it is going to depend on them and how good/familiar they are with the bike. KTMs tend to be a little weird and take longer to get parts for than say a honda or yamaha.
