You can shine a flashlight into the hole to see the slot in the crankweb at TDC to see what shape to make your point....

Just measuring up the KTM OEM locking screw and it has about 25mm of thread....

Good luck...
Thanks for that info. I found your post about this from last year but wasn't too sure.
Will take a photo of the mesh filter to see the debri from the cam.
There wasn't any sign of metal when removed the front spin on filter and drained the downtube.
Lots of fine-ish metal and very fine dust like metal around the two bottom magnetic drain plugs tho.
Haven't taken off the RH paper filter yet. Tomorrows job.
