Just thought I share an easy mod I made to my bike to make it a little easier to work on. I used a length of 3/8-16 threaded rod, two couplers and two lock washers. It makes a nice lift point for your jack.
Careful of using threaded rod for engine mounts. I used it a fair bit to mount racing engines and I seems to snap fairly easy. Even the HT stuff. I am not talking about high power engines either. had trouble mounting a Honda H100 and CR85 motor in a Honda RS125 frame ( special class racing). Ended having to go back to finding the nearest size proper engine bolts. I suspect the rod lacks Moly or vanadium need to handle the vibration.
