Bike stays in gear with clutch in

I have a yz 125 2001 model
when i put the bike in gear and hold the clutch in it stays in gear, the clutch lever has tention as it should , ive been told to see if the arm pulls the presure plate and it does
the problem seemed to come from no where. i was out on it one day, parked it upand left it until, the next dae and the problem was there.
i have checked the clutch friction plates and everything it all seems to be in good condition ,justa little bit sticky because if the oil but ive been told this is normal.
it shifts gear easy and works fine neutral if that helps anything
help would be really grateful .

You are saying that with the clutch lever pulled in the bike still wants to go forward. Generally that is caused by dirty, gritty oil in the gearbox. Go ahead and change the oil. 10w40 motor oil is what you want. I think that will fix the problem assuming the clutch plates were installed properly. The first plate installed and the last plate installed should be a fiber friction plate, 8 plates total. A metal pressure plate goes between each fiber plate, 7 plates total.

Be sure the lever assembly arm is installed so that it gets full movement of the clutch cable. If the full range of movement is not present then full disengagement of the clutch is not going to happen.

cape cod bob did you a good service in the manual referral. Be sure to say thanks.

2002 yz 125 when I put it in gear it will shut off acts like the clutch is not working when I adjust it on the handle bars it slips


Mechanical issue: clutch not disengaging completely...
engine off - put in gear and roll back and forth with clutch released does engine stop the bike from rolling? Now pull clutch lever in and try rolling again is clutch cable adjusted properly?
Electrical issue: bike thinks clutch is still engaged and kills motor when not in neutral
Is the clutch switch properly connected and working? Is it adjusted properly? Use a multimeter to read resistance across switch contacts does it change state when clutch is pulled in?

I need 2,3 & 4 gear for Yamaha 1100 special 1982 model


Instructions
    • 1 The gears on a motorcycle run in this order: first, neutral, second, third, fourth and fifth. When you are moving, shifting up from first gear will skip over neutral and shift you right into second gear. The only time that shifting up from first will get you into neutral is when you are not moving.
    • 2 Pull in the clutch lever and tap the gear lever down until it stops. This will signify first gear. Pressing the gear lever down will shift you down one step and pressing it up will shift up one step.
    • 3 Tap the gear lever up one click while still holding in the clutch. This will put the bike into neutral.
    • 4 Start the bike. The bike needs to be in neutral to start.
    • 5 Hold in the clutch lever and tap the shifting lever down to shift to first gear.
    • 6 Release the clutch slowly and give it just enough gas to get moving.
    • 7 Listen to the motor to know when you need to shift. If the engine is making a low grumbling noise, then it will need to be shifted down. If it is making a high squealing noise, then it needs to be shifted up.

I put the bike in gear but when i pull the clutch lever in, it wont disengage and stays in gear??


if the clutch lever feels it has plenty of tension, it may just be the clutch plates stuck together from sitting.

Roll start it and ride around while holding in the clutch, vary the throttle, and they usually unstick. Give it an oil change when it warms up.

No clutch control,bike stays engaged in gear with clutch depressed


assuming the cable is fine and you have pressure at the lever.sometimes the plates can stick together when it sits for a while. put it in top gear 6th, put the front wheel against a wall, hold the clutch in and put some weight on the kick start. or push start it and hold the clutch in and vary the throttle to try and free the clutch

I have a yz 125 with a rebuilt motor i put the nuw motor


A very common problem with wet clutches is that many folks do not use the correct oil. The plates in the clutch are sandwiched under spring pressure and there is nothing in the mechanism to release them, so if the oil creates too much "stiction" then the plates can become suctioned together.

I suggest first trying an oil change using an oil designed for use with wet clutches. Then, get a running start, hop on the bike and drop it into gear. Then pull in the clutch and while holding the clutch lever in, rev the motor to break the plates loose. If this fails after a few attempts, your plates could be rusted together - possibly from a leaking waterpump seal or a ride through deep water. A simple tear-down of the clutch will tell the tale and this can be done without buying any parts if you are careful.

Clutch will not disingage when i pull the lever .


Sounds like it is not adjusted properly, or you have the clutch misaligned. You can check for proper operation with the bike off, and the clutch cover off while pulling the clutch lever. Should be able to see it move 1/4-3/8 of an inch.

'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
