Another fork question...

[Trimmer]

I was reading all the fork conversion posts and found one answer, but not the other so here it is.

2004 KX250 forks and triple clamp on my 2005 220.

The stem has been swapped out from the 220 to the KX clamp. There is too much slop side to side. (the top of the stem, and the center hole of the top clamp)

The shim/washer idea seems to remedy the up and down problem, but not the other.

Any ideas appreciated.

Update: I'm having a collar made.

With or without bearing?

No, the cranial density is quite heavy over here Ryan when it comes to this stuff.

The complete KX forks w/triple tree (and bearings) is assembled and mounted to my 220.

In other posts people have mentioned stacking washers below the top clamp and above the stem nut. I can see this working but...Where the stem sticks up through the top clamp center hole, the inside diameter of that center hole is considerably greater than the OD of the stem, allowing for about 4mm of space surrounding the stem.

The guy doing the work for me is going to machine a collar that will serve two purposes. Replace the washers and snug the stem in said center hole.

I didn't know if the 05 220 bike and 04 KX250 forks had a change in design that would prevent this match from working.

Everything else seems to be fine, I happened on a good deal for a complete set of black excels/gold hubs (with new tires and rotors even) off a KXF. I will probably need to buy new carrier rings for the rear hub and the front is already on and looking rediculously nice.

Thazz-all..thanks guys

o, ok i did this conversion myself, with 99 kx forks acutally and i did the same thing. Instead of using shim stack, a buddy of mine made me a spacer with a very thin sleeve to act as the shim. I still needed a spacer though.

Trimmer-I had a Collar/Shim machined and it works great. There will be a small gap between the collar/shim and the steering adjuster (one with the noches in it). Place a washer between the two or it will back out and you will have major slapping up & down & side to side. Trust me on this one.

Thanks GH...I'll do that.

I'm off for vacation, I'll post pics of the finished bike when I get back. I have a week to figure out how to explain to my wife the new excels when the bike comes home.

Yes, she'll notice.

Too many Questions!!!

There are like a million KDX riders wanting to know what forks fit on this year or that KX swap over with little or no work. Why not just buy a KX and make it woods worthy? It is easier to detune a racebike than dump a ton of money into a woods bike that is will probably never live up to your standards. Yeah the initial cost of the bike may be more but a bigger tank and bark busters are usually cheaper and less work the trying to cobble some front end off god knows what onto a mediocer bike. JUST BUY A KX...

Anyone else agree?

I don't really agree.
The KDX motor is perfect for the woods for me. I've got a slightly modified 220 motor.
My opinion is that trying to detune a KX motor into a good woods motor will result in a poorly running KX motor.
The KDX's biggest weakness is the stock front forks. They really suck. They can be improved to be pretty good, but can't seem to match even a set of poorly maintained KX/YZ/CR forks.

Of course trying to turn a KDX into a MX capable bike is a waste of time, in my opinion.
Making the KDX an even better WOODS bike is easy with some improved forks.

I ended up building a hybrid. '99 CR250 chassis with a KDX motor in it, so I am kind of agreeing with what you are saying when it comes to detuning a MX bike for the woods. I just prefer the KDX motor.
