Not much to report.
Just making brackets and threaded tabs for the cdi and coil.
Our welder is about two weeks out so we are stuck making busy work on it...
The four stroke engine: That's one stroke for producing power and three for wearing the engine out.

Before it goes to weld we are gonna make templates of everything.
I really want to see if we can make this happen with the 500 engine.
I'm doubtful but you never know what a little tweaking might do  :lol:
I have no interest of making conversions for others as there is plenty of skillful people doing it.
But I will share what I learn and showing what you can do with some very basic hand tools and some elbow grease..


the 500 motor does only need a little bit diferent front mount ...  i noticed this as i did my 93 steelframe conversion ..  8-)

in the meantime a pic of an bad welded honda-conversion-frame...

You know that guy is sick to his stomach looking at his bike.  That frame is trashed!
Perhaps I have a dirt bike addiction?

and more as good to see the clear break of the bad weld over the y-section ... the rest of the frame cracked like a joint as result of the y-section-break 
note that it is straight like cutted in the next pic

 

bu t nobody of you all had seen the dual silencer  :wink:

I missed the twin mufflers  :-P

Yes, the Y area is always a concern.
The Y section wasn't the best design for that generation of frames and Honda continued to update it to improve the weld surface area.
We have a few things that we are going to do and see if we can make it better  :-o

i know you are able to do it to perfect bike-finish..   :wink:  ..maybe on your kx500-al-frame-project or on the supermoto-bike you will do the twin muffler thing ... i think its getting a better weight balance and a amazing look...  8-)

thats not the stock yoke in that CR photo. thats one of those machined yokes off of ebay.
looks like the actual pocket of the machined top cup broke off. very odd.

Nope... It's a completely stock 01 CR250 cradle.
If I do another this way I will probably use the 03 CR250 cradle..

wow, the valve cover is pretty tight to the frame in that pic!
or is the motor just sitting in there unbolted?
