Good looking bike. Like your paint scheme and pin striping.
I have ran Motorex Synthetic 2T in my Ktm 2 stroke dirtbikes at 50:1 for years. It runs clean. I run it mixed at 25:1 in my 165 and have found it to run almost smoke free, no 2 stroke puke and no fowled spark plugs. Its good stuff.

I have a 1953 ST. In 1953 the book said mix 25:1. Modern two cycles mix at 50:1. Is it the modern engine or the modern oil? What's the party line on what the mix should be?
