Inheirited an ole Manco 2-seater... any do/don'ts?

[Half-breeder]

Looks pretty cool but i would be a bit worried, your head being that close to a angry 250cc motor reving to 7000rpm but thats just me

Yea... that worried me too for alil bit... then I found a 3/8" bent piece of aluminum sheeting and an equally sized/shaped 1/4" steel piece of sheeting... NOT saying those 2 combined will prevent an injury 'IF' something goes snap/boom/bang wrong... BUT... by theory they 'should' help considerably. And if anything they'll deflect alotta the heat that will be radiating off the header/head.
