[sjrdr]

hey all, will be pulling the clutch out tonight and need to gather the tools. do you know if the center nut is 27mm or 30mm? thanks for the help.

2004 YZ250

It's 29mm..which is pretty rare in most tool sets.

it was either a 27 or 29 for us. Sorry but don't remember...We bought an impact wrench set that came with most sizes because previous owner messed the clutch up pretty bad.

lucky for me i had a 30mm on hand. it worked like a charm!

It's 27mm for the 125, positive it's the same for the 250 ?

[Syrpe]

So, which size was it??

?

[sjrdr]

it was definitely a 30mm.

[brentn]

Part numbers are def different for both the 125 and 250 of the same year

05's for example are;

YZ125

NUT,HEXAGON

90170-16326-00

YZ250

NUT,HEXAGON

90170-20255-00

Damn, I was really really hoping that the 250 was the same size bolt, now I gotta buy a friggen 20$ socket again...

*edit*

Confirmed, this is a 29mm nut for the 250!
