My YZ-125 2004 says 6500cm3 on the gearbox. That seems like way too much. I'm really confused

[RockyMountainATVMC]

@lolcats121 - Its oil capacity is indeed 650 mililiters.

does it matter if I just do the drain plug and not bother with measuring the torque etc...and just do up as tight as possible?

[RockyMountainATVMC]

@OBS3RVE - as tight as possible?? There is a good chance you will strip bolts out if you do this. With experience, you get a good feel for how tight a bolt should be. To be certain, use a torque wrench.

[RockyMountainATVMC]

@OBS3RVE - It should hold the 650cc (650ml) fine if you are draining it and measuring it right. technically the 650ml is the volume when it is totally dry, which is almost impossible to do - there is always some old oil left in there. So 650 will slightly overfill it, but not enough to matter. Drain the oil when the engine is still warm so the oil comes out better.

I'm going riding in a couple days and dont have time to have the preferred oil shipped. I'd like to change it before I go so I can start fresh but I'm hearing that you can use several oils. Some say 30 to 40 weight engine oil some say 80 to 90 weight gear oil some say tranny atf. What would you recomend to get me by till my order comes in?

[RockyMountainATVMC]

@ferebeescott211 - It depends on the bike you have. Refer to your manual to know exactly what should be used. I wouldn't use an 80 to 90 automotive hypoid gear oil if that is what you are referring to. If nothing else is available, use a 10w40 motor oil. However, I would suggest motorcycle approved oil when possible.

@fokenWiannjopous Okay thanks. Well I put maybe 50-100ml too much, but It's recommended to put 100ml more than noamrlly after engine re-build so I don't think it's so serious even though my eninge was not re-builded. Well it's being rebuilded right now.. =) But it's not because it broke :)

[ismokewead420]

@OBS3RVE the point of a torque wrench is to prevent overtorqing/undertorqing bolts. as tight as possible is the worst thing you can do in most situations

[fokenWiannjopous]

@tooumas could cause exessive pressure in your gear box when the oil or any air heats up and expands. Might blow a seal or gasket in worse case senario, not sure if it will effect your gear selection that might only be with thicker oil

then again im not sure if 50-150ml is over filling, better off just doing the homework and finding out the right net amount

@88yougurt88 I have this same problem with my 2010 YZ 250, I honestly think it is a bad design and the check bolt is just obviously way too low. I always went by the check bolt on all my other bikes, but not with my YZ. I just put in 800 mL of Yamalube. I put a bit more than 750 because I usually warm up my bike good before draining the oil to get more out. Anyone else know why the YZ's check bolt holes start pouring way too early??

[88yougurt88]

hi ihave a 2005 yz 125 my bike says 650cc of oil and it wont take it i put about 300cc into it and it starts pourng out the check oil hole help
