My dt wont stat in gear with the clutch engaged?

Check there is free play at the clutch slave cylinder , if the cv joint or drive shaft is broken it should make a noise when in gear with clutch engaged .

The gear box should be okay. Check the clutch-watch if the clutch fork on the bell housing moves when someone presses the clutch. If it doesn't move, the cable needs adjusting, or if hydraulic clutch diagnose the clutch master and slave cylinders. Either one should cause the clutch fork to move and engage the clutch.

If the tranny will not shift into third (or any other gear) the problem is a bent shift fork. As far a clutch slippage, don't use any type of synthetic oil or oil with "Special" additives. Just use standard motor oil in the gearbox. Be sure the basket and center hub don't have wear notches from the plates. This can cause the disks to hang up on a notch, thus not letting the plates to fully engage.

If you select a gear without pulling clutch in it will grind and stall.
If you are certain the bike is engaging a gear and still seems it is in neutral, your clutch drive is broken.
Alternatively, the gear selecter fork bolts maybe loose behind the sidecover, allowing selector to partially engage only and return to neutral. Try selection thru' higher gears, place bike on a stand and turn back wheel in gear, if gears turn and motor doesn't...it is the clutch. If you cannot select a gear proper with rear wheel turning, your selecter is suspect.
Goodluck, and Cheers.

it will be down to adjustment, there are 2 ways to adjust one close to the engine casing and one at the lever just have to get a good balance :)

Check hydraulic fluid for clutch pedal.

i actuall have a yamaha enduro 100 and had this same problem.
First thing is take the clutch apart take all the rings out and clean them good with momry cloth assemble the clutch compleatly as it came out and when tighting the springs tight them all one turn at a time and after everytime you go around try to move youre clutch with youre bike in gear. if it trys to move it is engageing just keep turning the screws untill they stop. also recomend putting threadlocker on the drive gear bolt and the clutch bolt that holds the clutch on. if you have and questions just e-mail me at [email protected] just make shure to tell me that i responded to youre fixya question about youre bike and i will walk you threw it.

ps just rember to put the clutch pushrod back in

Is it not engaging, or not disengaging? Does it just slip when you put it in gear and let out on the clutch? You can try a clutch adjustment, but may need to look at the clutch discs themselves.

Does it have a kick stand interlock switch? If so, the stand needs to be up when you select a gear, or it cuts off. If the switch is bad or out of adjustment, it will cut off when put in gear.

if it wont drive how do you kno its engaging if it is in gear and you arent pushing in the clutch it should move forward if it doesnt move then you will have to replace the clutch
