KX 125 - 1998 # Bought for a rebuild

[Hugo4x4]

Heres my bike that i bought yesterday for a bargain, the owner said it was a 1998 KX 125 but i'm not sure about the engine's year.

Can you guys tell me?

The idea is to transform the kx into a enduro bike. Now it doesn't have compression, it starts but the ex-owner said the piston is knocked-out.

Now the pictures that i took, and that the ex-owner send me 

Thanks!

interesting...that the engine case serial #, I believe, is of a '99 KX250.

I also thought of that, they said that this rod is stronger than the kx 125 '98 stock one and that the engine case is from another kx that he had...

here's a good way to verify the "bikes" year, just to be sure it's a '98....ignore the fact that it says KX500 VIN#, as it works with the 250 & 125 the same way...
if yours really is a '98, the 10th digit will be a W.

The frame i guess it really is from '98~'98.

But the engine i really don't know.

[Hugo4x4]

So i was checking and this is the real engine number Anyone?





New front mudfender and removed the vinyl on the front

It's either a 92 or a 93 engine...
Probably a 93..
If you have the cylinder, check the numbers
1672 is a 92
1687 is a 93

[Foxx4Beaver]

yup, "J" indicates the model...
now...that swing arm, doesn't jive as '98....that's a '94-'96 swingarm.

have you checked the frame VIN# Hugo?...you'll find it on the right hand side of the frame neck.

Thank you guys! Do you know of this engine is good in terms of power or better buy a more recent one?

About to send the cylinder for a nikasil bath.

What about piston, wiseco, wossner or oem?

[Foxx4Beaver]

wossner, all the way.

[Hugo4x4]

wossner, all the way.

That's also the brand that i'm more about to buy.

So here's the last video of my bike after the rebuild.

Hope so send the cylinder do Airsal this week
