We almost tacked the frame rails last night.
But, I want to take a trip to the nearest KTM dealer with my scale and tape measure.
Verify, verify, verify...
Once I'm totally happy (I think I am there now) I will take the setup to my welder who use to tig weld chromoly bicycle frames and have him do a nice job.
I'm sure that Jason Tanner could weld it but I'd rather have a professional do it on this project.
We are currently removing the engine mounts from the old frame rails and seeing if they will work..
It's funny how close the stock KX500 mounts are...
