yz125 cylinder interchangeability

[mhall41]

I have a 1991 yz125 and I am curious if I could use a cylinder off a 1990? I've read that 90-92 parts do interchange but just want to make sure before I spend the dough, any input is greatly appreciated.

They look the same to me in the parts diagram but they have different part numbers. Hopefully, someone else knows for sure.

Every year of Yamaha parts have a different part number even if the parts are identical.

I am 99% sure the two cylinders in question will interchange.

Ossagp would know for sure...

I thought they looked the same as well.

I didn't know that even identical parts had different part numbers, it would make it much easier if they were the same.

In that case, I would get it because the parts diagrams look identical with the same powervalve and everything.

I went ahead and picked it up so hopefully it works. Thanks to everyone for the input!
