SHLEPY:
Im scared to death of my frame breaking with out holes through the rails thanks to my mistake of going to george at MPS but it may be a differnt animal for you it would be alot neater looking.

sandblaster:
Yeah, there are good and bad points to doing like I want but I think the good outweighs the bad.
Thanks for your input.

I know a lot of guys weld the mounts directly to the frame but it will make engine removal in this 250F frame all that much harder.
So, I am thinking about drilling through the square tubes and welding in aluminum tubing and running bolts all the way through the frame tubes.
Here is an example:



What do you think about that?
Or, do you have a better idea?

ahh.. the AF section.... the section of the site Im never in....   But since My presance was requested..

where on the frame tube would this end up?   middle?   

Take a picture with you pointing at the frame where the hoels would be... 

cmotodad:
Not too revelent but I am doing my CRF250 to KX500 and in the section to raise the Y I put solid stock in then drilled and tapped for removable front mounts. Will post pix soon.

 That's the best way to load that rail. Make the wall thickness of the tubes as thick as possible to prevent buckling under compression. Not a place to try and save weight. A M8-1.25 SHCS (Class 12.9) can generate about 6000 lb. clamping force.
