welcome SOHC!
good lookin '90...what forks are on it?...don't look like the stockers.
-
Choice bro! Nice to see another 90 being brought back to life. Mine has gold forks as well maybe different forks for different markets?
-
Hello
They are stock forks but they are very rotten, big chunks flaked off about 4mm deep, they are too corroded to use.
I have a replacement pair of blue 1992 forks witch I have polished silver and I need to make a custom axle as the 1992 forks have a bigger hole where the axle clamps, and the 1992 axle doesn't work with the 1990 hub bearings.
other option is to remove the aluminum parts off the steel stanchions and swap them over, I understand they are very hard to remove.

I was gonna say....I don't remember the stock 90's having such a deep bronze look :lol:

Its probably the light in the photo but that is the stock color,
-
could be the light...
they probably "browned" a little with age too ...I had a new '90 in 1990 and don't remember them being that dark looking....

If you measure the chrome diameter they should be 41mm.
1990 was the only year with the 41mm forks.
The reason I say to check them is because if they are 41mm then the blue forks won't fit the triple clamps correctly.
I'm not saying you can't gag them open enough to make them fit but they won't be correct.
-
Oh s**t thats something I will check now, I guess I will need to find another set of yokes.
-
I just had a look, your right the 1992 forks are a 1mm or so thicker, I had a quick look at my parts and I have a set of yokes for a 1992 KDX250, the bottom yoke only has 1 clamp bolt on each side so is no good but the top yoke will work as it looks the same as the KX, and the whole fork leg tappers so I will just put it in the lathe and turn it down to make the bottom yoke fit. or just find a set of 1992 kx yokes
-
I just rang the wreckers and bought a pair of 92 yokes,
-
And.... Your front brake caliper, wheel, and axle should fit perfectly :mrgreen:

I know about the axle problem, I was going to make a custom one but it is looking more like swapping the bottom alloy parts of the forks over now
-
Would someone be able to give me the front axle diameter where it clamps into the forks for a 1992?

Cool thank you I will have a look at that tonight.
I got my new yokes to fit the bigger id forks and now they don't fit the steering bearings, yay.
But I have a cunning plan, I will press the steel shaft from the 1990 into the later bottom yoke and use the top yoke from a 1992 KDX I have
-
Yep.. The bearing changed in 92.
Check the link :lol:
