Try one off of a yamaha seca 400
try the yamaha seca store.
Maxim 400
It should be an 12N 12A-4A battery
The correct spark plug for this motorcycle is: NGK D8EA
0,263 litre 10W30 oil
my manual for '82 seca 400 says "Periodic oil change: 2.2 liters / 2.3 us quart .... With oil filter replacement 2.5 liters / 2.6 us quart"
According to WikiAnswers, the proper battery for a Maxim 400 (the Seca's sister) is 12N 12A-4A. I'm looking for one also. This is the same battery I used in my '72 Yamaha XS650 although it had a "-1" designation at the end.
the only place i have found is www.targa-acc.com there like 400

According to the parts list, no, but they should be interchangeable. They just are built for their specific purpose.
how do you know if your yamaha atv is a 400 or a 450
