Im wondering if a 2007 big bear has any interchangeable parts with other 4 wheelers. Im about 99 percent sure the bb and Kodiak have some interchangeable parts, but what exactly? What about the grizzlies?

 

I think Yamaha uses many interchangeable parts on there ATVs for cost saving.
I use this site to match up part numbers for different atv parts when I need to know a part from e-bay will work or fit. Dirt Cheap Yamaha, Honda, Arctic Cat & Polaris OEM Parts & Accessories – Cycle Parts Warehouse

 

So as long as the part numbers match I can use it? Sounds simple enough thanks.

 

does anyone know if the exhaust from a grizzly will fit a big bear? I checked the part numbers and the griz was I think e4711 and the bb was an e4710 I do believe but every other number matched.

 

Which Grizzly? They have 4 completely different motors in a Grizzly. A 350 air cooled and 450,550 and 700 Liquid cooled.
The closest to the 400 Big Bear is the 350 Grizzly there the same motor but the 400 was stroked to a 386cc but they have the same bore.
I,d just be concerned if the two frames of the ATVs are the same so the pipe has the correct bends.
Do the pipes look alike on the Parts Site"s picture? Maybe all it would need is a re welded mount bracket or something.

 

I got a 2007 HSUN (HiSUN) 400ATV in trade for some ATV work, and
it seems to share many parts with the Yamaha Grizzly/Bruin/BigBear
350s. This unit was so rusty, I dumped it. It sat near the ocean for
a few years.

 

I need more help on this subject. I look at the part numbers and they'll be like a letter or a number different, like just one number or letter everything else would match. how would I know if itll fit?
