grim..
i have pipes from FMF for the KX500AF conversion,(KXF450 based ),
 but they would likekly work well in a kx250 to 500 conversion as well..?

but to be honest FMF simply took the low boy CR500 stamps, redid  them slightly,
and yes they are dented to clear that water fitting,,
and not quite enough, =/

so i make a water fitting to change the hose angle slightly.. so all then clears well.
(on the production KX500AFs i am going to both use that water fitting, and mill the cylinder where the fitting  bolts to,  as there is plenty of material there to take down and help with clearence in a critical area..

with that said-
let me know if yioy want to give this pipe a try.

I have pipes to they are the zip-ty low boy pipe and they fit perfectly and they were made for the kx500 I have been waiting on mufflers but totaly got screwed on that after waiting for monthes. I had posted that the dies to make these had been destroyed but that turned out to be false. I coud have more stamped but Its a large envestment and after all the crap I have gone threw tryng to have mufflers made I do not know If I want to deal with It

saw your bike BDI,, nice work man.

and yeah i thought you had styated the dies were destryoed ..
as i anted to get one of those pipes as well to try out ..



i do have silencers,both regular and Q,
 but they are made to fit with that KX 500AF pipe -
so its desgned towars the  450 subrframe-
but,
 hey they might fit up with your pipe as well..?

i would imagine guys doing variuos conversions could work out the brackets,, ??

ive certainly cut them off often enough in the past for proto type bikes  and relocated them?

just a thought for those adventurous enought to be doing the KX250 conv,
 or whatever other conv..

Thanks AJ your bikes are not half bad either. you see my problem Is this I need a muffler to build the pipes to so the whole project has been put on hold. I was supposed to be getting a brand new 06 kx450 with no motor but that deal  got screwed up too I have had a string of bad luck on my new bike project the bike was supposed to be built by now and I have not got one pipe made. :|

The reason I would stay away from an 03, its kind of a 1 shot wonder, 99-02 are pretty much the same, 04-07 pretty much the same. If you were to get the whole bike the 03 would be fine, but if your going to try to get the parts don't use the 03 as there aren't as many, primarily swingarm and linkage are the biggest difference. I've pieced them togather from parts off Ebay and rarely do find 03 parts. I had an 03, it was a great bike, just all alone in design.

 Can anyone provide more info on a 500 motor in an '04 - '07 250 frame? This is a conversion I would love to tackle and I just want to see if there are any more "little obstacles" to overcome in doing this swap. I've tried the 250/500 search a couple of times and can't seem to find anything about these year chassis'. I like the fact of the newest 250 frames having the head stay in the rear.  Any photos, links, or other info would be greatly appreicated. Thanks!!

 Well, I've made the first step toward doing my own conversion. I picked up a complete, great running 1993 K5 locally here in SoCal. This is definitely gonna be a slow process for me, just for the fact that I have waaaayyyyy to many projects to finish first. I just couldn't pass up the price on this one. Plus I have my '04 500 and '01 250 to hold me over until I join the best of both into one bike. I just couldn't bring myself to rob the heart outta my '04. (Being a last year K5 that I bought new in August of '04, I would of felt like I was killing that beast.) :evil: :-D
 The '93 has some cool extras too. Talon rear hub, Pro-tapers', FMF pipe and silencer and whoever had the suspension redone had the Blue fork tubes stripped and re-anodized black. They look great! Like a factory applied coating!
 Again, I'm looking for any extra info regarding a 500 motor in a '04 250 chassis. So, if anyone can provide some insight it would be greatly appreciated.
Thanks guys!!
Nick

I've kinda backed off for now.  I'm having a hard time swallowing that I'd have to sacrifice a perfectly good bike.  Maybe if I find a good deal on an engine......

Waiting for my 01 chassis to arrive. Suspect I will sell the bike off this spring though as its really overkill for a daily rider that isn't drag racing or sand duning.

I disagree... big-bores makes prime daily riders... IMO the tractor like low-end power makes them easier to ride...

Hope so, means I don't have to sell and can save some money over buying a new one.
