Hey Guys,

which radiators did you use for your build?

We will use the KX 500 radiators...
right side is fine! left side is very very close!
It would be nice if the left radiator will be about 1 cm shorter...

i used also the kx500 radiators, because they fit perfekt to the 93 kx250 -steelframe, that i used.
why dont you try to lift up the left radmounts 1cm on the frame. would be much easier as cutting and welding on the radiators. you must only look for enough clearance, that the frontfork can´t hit the radiators by turning full to left and right .

where are you in germany?. i live in the northeast in mecklenburg/vorpommern...

We are coming from near Frankfurt/Main.

All radiator mounts have to be new! The problem is less space between the Fork and the Y Frame section!
But it will work! If we do not short the radiator it will be fit a little bit diagonal...
The mounts on the picture are only for testing, we are looking for reuse the old mounts to be new welded at the right position!

and so i hope i can get it cheap with blown engine and maybe i take my kx360 engine for the af-build. the time will show it, what happens in the future  :-)

Oh yeah, that would make a cool bike....
I hate to wish your buddy ill will............ But..... KX360AF .... Nice  8-)

thats the plan   :-D  i´ve said to him, if he dont look better to his bike he will destroy the engine. he smiled and said: this is a kawasaki!!... so all i have to do is waiting ...  :evil:  we´ll see what happens :lol:

i think youre y-section is a little bit to high, but the fitment of your radiators looks good at the first view.  dont forget the clearance also to the pipe... which pipe you´re planning to use??

YES next bike we will will make the "Y" a little bit lower!

I bought a new DEP Pipe and DEP silencer for CR 500.
We want to adapt these to the bike. Also i have the old KX pipe to reuse the connection to the engine!

The four stroke engine: That's one stroke for producing power and three for wearing the engine out.

PIPE: Honda CR 500 /DEP
Silencer: HONDA CR 500 /DEP

Exhaust is fixed and point welded...
If we short out the pipe for 15 MM we could reuse the silencer mount.
We want to cut the pipe at the weld in the kickstart area and cut of 15 mm there.
We had also fixed the engine connection from the KX5.
The silencer should be shorted at the end.

sorry for bad english  :roll:
