Cuts out when i put it into gear

SOURCE: '95 Yamaha YZ 125 clutch - stays in gear when clutch is pulled in

hey dude,, just thought id come in and give u some tips or 3,, i take it when u pull clutch lever in, and try and change gear it feels like your foot will snap b4 it goes in gear,, if that makes sense,, firstly mate,is to make sure the clutch cable slides freely ,easest way is to take cable off and just grab 1 end and make sure it isnt sticky,, if so dip one end of the cable in a bit of old oil ,,whilst holdin the other end ,pull and push the cable inner, this will **** up a bit of lubricant inside the cable ,, keep doin this each end till free to move, ,,next step if the cables ok,,, and may need help if u dont no,drain the oil out,,and as u r sat on the bike is to remove the clutch casing on the right hand side of the moter,where the bottom end of the cable goes,remove the casing being carefull not damage the gasket,,then u will see clutch plates and friction plates housed,, undo the 7 or 8 spring loaded bolts carefully take the first fibre plate out then metal friction plate then another fibre plate and so on,, wen u take the 1st plate out place that on the bench ,stacking each plate on top of one another, cause they have to go back in as they came out,,wen out,,u need a piece of wet n dry paper ,or fine emery,,and just wipe round both sides of the fibre plates taking the shine off them,as u put them back in,, put casing back on with a decent gasket,, oil back in cable on, make sure cable has no free play on the lever so wen u r about to pull lever in it bite straight away,, start her up, warm it up and try it,,any probs still il eat my shoe,, take care m8

Paul,
Your Yamaha seems to be needing a clutch adjustment.
You can adjust this on your own by turning the adjusting nut out (at the handlebars) to take up the slack. If that doesn't fix the issue completely, turn the nut back to where it was, and adjust the cable at the clutch housing (right side). Start in small adjustments, and work your way from there. When you get it close, go back to the adjusting nut located at the handlebars and do the fine tuning there. Be sure to leave some slack from full release of the handle to where you feel the clutch tension start. If you don't, the clutch will not fully engage. If this doesn't fix the issue, let me know and we can go from there.
Hope this helps

SOUNDS LIKE IT COULD BE THE SAFETY SWITCH FOR THE KICK STAND ,IF THE SWITCH HAS BEEN DAMAGED IT WILL START UP FINE AND WHEN PUT IN TO GEAR AND CLUTCH IS RELEASED IT WILL DIE.(This is a safety feature)

If that don't fix,Please post back

I would be more concerned with the stuck gear than the clutch, but we will start with the clutch.

The push cam may be bent or deformed and the push shaft may be bent. Assuming the ball bearing is in place, the cam and rod are all that can really go wrong. The rod slides out of the left center case. You will need to loosen the springs to get the left side cover back in place. Roll the rod on a flat surface to see if it is bent. I fear a bent shift fork is causing the gearbox to be stuck in third. Fix the clutch and then post a comment to get back to me.

i had a simuler problem with my honda cr 250 moto-x bike it would start fine and you could keep it ticking over with the throttle(i have deliberatly unscrewed the tickover in case i come off,it will cut out) when i got on it,it would go for about 400-500 metres then splutter and die and not start again for around 5 mins. i immediatly knew it was a fueling problem. so after stripping the carb and giving it a good clean out i was baffled when i got back on and it still done the same. i then dismantled the fuel tap cleaned it all out and put it back together and tested it,it was very very slow so i unsrewed my fuel cap a little and was greated with the familur gush it should deliver. problem solved! the vent in my fuel cap had crystalised up,so the fuel was coming out but the air was not getting in,causing a vacuum and slowing down the flow and basically emptying the carb quicker than it can fill back up!!! clean your carb,fuel tap and any vents in your cap or tank. if this does not work then your bike must be over fueling or low on compression.
