Re: first build murry montery
if that monterey is older like the one i got (guessing probly 70s/80s) from a local bicycle bone yard,
i wouldn't put a china-girl on it let alone that 4-stroke... i was thinking when i got it, same as what others have said about welds/gussets to make it stronger. my son tried and problem is, the tubing is so thin he couldn't weld it without burning thru.
just my opinion, and speeking only of the frame i have, but i wouldn't motorize a monterey.
