KXF 250 2007 for KX500AF

[Dutch-K5 Fan]

Today I've take the K5 engine out of its frame
and took a quick look how it would fit.
It looks like "only" the Y section and some engine mounts are in the wrong place.
First I'll take the cilinder of and will drill the swingarm bolt hole. Thinking to take clutch
cover and clutch basket/hub off for smooth survice to rest on.
Will post some pics next time( if the battary's aren't empty)

Saterday gone drill the swingarm hole up to 17mm, and try to put the engine
cases into the frame so I can see whats in the wrong place.

not sure you can get the motor in the 250f chassis without cutting it, even with the cylinder off I think it is to long.

Because of some family matters I haven't done much with the bike.
And It's standing at work, have no place at home. normaly its in my fan.
But yesterday in my lunchbreak I have drilled the swingarm hole up to 17mm, was a easy thing to do.
It whas a 45min job to take the clutch and cover of for smooth survice, and drill it.
Today put the engine in, and it doens't fit in the front. But now i now whats in it's way and what i have
to cut out the frame.

Should I make a welding calibre( If translated correct) for deforming when welding on the frame?
Or Is that not a probleme? The main frame tubes are BIG and massive.

WooHoo. Progress in action. I know you can make it work.      If you get the angle that the axle, swingarm and countershaft make the exact same as the KXF450 you can run a stock spark plug. Anything less...its a shorty. I hope you dont have to convert yours to diesel. Lets ponder....Detroit 8-71, 6-71, 4-71 and the new KX 1-30
More pic please.  JFAB

Looks like Point of no return

Diesel engines have more torgue , so might be a good idea

I cut the main tube just a bit higher than the lowest point of left radiator.
But the gastank and plug info is a good idea. Didn't thought about that realy.

As you can see the frame came to holland by Canada.
The old owner made airvent from the engine case true the frame, so when cutting there
came a lot of oil out. Or looks like it's bleeding.
tryed to put engine in without cutting the Y section. It's to sjort like you said  Don.!!!

great man ,i ll be happy if it al works out just fine..
ik zal voor je duimen jongen  en hou ons op de hoogte 
oow and ill be riding from march or so ,we,ll catch up then 

[Dutch-K5 Fan]

Thanks MAN.

Frame works is the first step, for the front exhaust I'm using the HGS from my
self or my uncle, stil have a hgs cr250 mufler and a stock one . Some mod's and I'm running.
Airboot from cr250 or kx250 and some aluminium.
Have some  idea's about Suspension. Heavier spring in the back. And if it doensn,t work, I'll go
first to my own local shop(Cross shop Vijfhuizen) or Reiger maybe. they can do wonders with that!!!!!
Reiger is threated like gold in rally sport and by  Gerard De Rooi.

The springs are the same basic part number for both KX500 and KX250f. The stock 250 has a 5.1 and most 500's that year are about a 5.6 rate. How much do you weigh?
