I have a 2001 yamaha yz 125 that i just bought it wont start or turn over and when you engage the clutch and put it in first gear the back tire drags i filled it up with mystery oil and tried pop starting it but nothing ....any ideas?
If the clutch drags you need to check the plates and the worse thing to do when a bike wont crank is to pop start it you just do more damage and defiantly only use the right oil

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

Yes, the water seal is leaking. This is the indicator hole for the water and oil seal.
Enjoy the ride !

the plates will stick to each other because of oil
check the clutch lever at the motor and make sure it is moving the arm that pushes the pressure plate and make sure it is moving
SOURCE: what oil should i have in yz 125 2 stroke
The clutch and gearbox share the same oil. The oil for the motor is 10w40. Stick with the major brands; Pennzoil, Quaker State, Mobil, Yamalube or Shell.
SOURCE: oil
on a ratio-rite there are hash marks for cc. a cc is the same as a milimeter
.65 liters = 650cc
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.
