It sounds to me like the clutch is stuck. If you hold the clutch in and rev the engine a few times, sometimes it will unstick the clutch.

SOURCE: Clutch problems Suzuki RM125

Do a gearbox oil change. Then do another one 50 miles later. This should flush out the dirt and grit currently in the gearbox. You may want to invest in a new clutch cable also. 10w40 motor oil.

SOURCE: Broken hook on RM125 engine that holds clutch cable in place

The best fix is one of the steel epoxy tubes you find in any hardware store. They work great and you can attach the broken piece back on or if it is gone actually shape a new one.

SOURCE: 2002 suz intruder clutch wont dis engage

First , there is no cable to adjust or check. Suzuki uses a hydraulic cluth release on this model. There is a tiny hole in the resevoir on the handlebar,check the condition of the brake fluid in your resevoir.If it has not been changed in a long time,2 YEARS or more,Change it and clean the muck from the bottom .Make sure the holes are clear.Flush the system with clean brake fluid down to the slave cylinder located at the lower left side of engine. What is most likely happening is every time you pull the clutch lever the slave is moving out,with the hole in the master clogged the slave cannot return, this is leaving the clutch disengaged at all times.I would suggest checking this out before pulling clutches out ,or the engine out to check shift forks. Best of luck to ya, Gixrfixr.

SOURCE: clutch wont dis engage cant find nuetra;

You either need to adjust your clutch, you have too much oil in your primary, or your throwout bearing has failed.

To adjust the clutch, follow the clutch cable until you find the rubber bellows near the down tubes of the frame. Slide the bellow up or down to gain access to the adjuster. Loosen the lock nut and adjust the adjuster inwards making the cable as short as possible.

Now, remove the derby cover on the outer primary cover. In the center of the clutch assembly you'll see an adjuster screw and locknut. Loosen the locknut and turn the adjuster clockwise until you feel a resistance. You don't want to force the adjuster screw as you'll start to release the clutch, go in just until you feel resistance. You may wish to do this several times until you get the feel for it. Once you feel the resistance, back out 1/2 to 1 full turn and lock the locknut. Reinstall the derby cover.

Now, go back to the cable adjuster and adjust the adjuster outward, making the cable longer, until you get about an 1/8" freeplay at the clutch lever. Lock the locknut and reposition the bellows. This should allow your clutch to release.

If you have too much oil in your primary, it will cause your clutch to drag and make it impossible to find neutral with the engine running. The oil level should be no higher than the bottom of the clutch spring with the bike standing straight up.

If you're experiencing difficulty shifting through the rest of the gears, You may have lost a throw out bearing. To replace the throwout bearing, you'll have to pull the chrome clutch release cover off the right side of the transmission.

Good Luck

Automatic transmission wont shift, its now in drive,so i cant shift it into park in order to start car. cant check fluid level blah blah blah. 2000 corolla

your gear is stuck , there is a little magic cover in front its base with tiny hole for a tiny screw driver to uncap it , and then use a small screw driver to push the lock lever down ( do that as you have your car switch ignition key on ON position ) and then you be able to shift gear to Park , then close that magic cover on that tiny hole .
if that does not work ? check if your brake lights are bad, harness melted , brake switch , or brake fuse .
Corolla tend to have that shut down of shifter as a safety feature .
if that is not the problem ?
then you have a shift solenoid kicked the bucket and need new one

I just replaced the broken shift rod. Is there a certain gear or position the drum should be in? I cant get first gear.

Whatever it was that caused the shift rod to break also bent a shift fork inside the gear box. The only way to fix it is to tear down the engine. Sorry.

Cant shift down into first gear

If not bent too radically, the shift pedal can be bent outward and away from the frame. Be sure the 10mm lock bolt is tight on the shift shaft. If it still will not go into first gear, the bike has a bent shift fork. The case must be split to get to the fork. Somewhat expensive to repair. Be sure to install new crank bearings and seals.
