Tightening Nut on Engine Frame Brace

by Doug Bridges

I recently came up with a solution to the problem of tightening the nut that fastens the left side frame brace to the engine on the early 175 KTM motors. Someone may have already come up with this, but just in case I am sharing my solution.

I took a 10mm coupling nut and screwed a 10mm x 5/8 Allen head bolt in the end and then welded it to the coupling nut. Then using a special Allen head wrench that allows you to tighten it from an angle ( bought the sets at Shucks Auto parts) I am able to tighten the nut even with the cylinder and carb mounted.
