Hmmm, choose your words carefully Brenden.
Firko, I have owned/raced a few evo/pre 85 490 maico's and I would agree that the motors don't deserve the breako tag but..... the overall finish of the bike leaves alot to be desired compared to a Yamaha.
Here is a list of things that happened to an "84 500 I bought new from geoff udy's ,
Exhaust melting fuel tank (twice), decomp handle bar mount pressed tin breaking straight away, fuel tap leaks from new, air cleaner mounting bracket breaking destroyed engine, rear chain adjuster weld breaking chain derailed into engine cases, bent shock, fork seals leak from new don't get me started on the rear brake lever or the rear brake backing plate, cables made of dental floss.
These things just don't happen to a jap bike of the same era.
Yamahas are like whores you just ride 'em then just lean them up against the shed till you want to use them again, Maico's are like the woman of your dreams you have to caress and pamper her every hour of every day, then and only then will she give you the "ride" you've dreamed of. Just so you know I've never been with a hooker, so I'm just guessing on that bit.
