GRKGUY--A measurment from you ir anyone would be greatly appreciated.  No my frame did not crack there but i have heard it is a potential weak spot--ounce of preventation thing for me...    After blasting the frame I was pleased to find no cracks but i did have two small cancer/rust spots that had to be addressed.

Once I get a measurement of swingarm to chain slider clearance I can determine if I want to add a reinforcing plate and then get it off for powder coating monday.
