1998 Big Bear 350 Carburetor Difference 2x4 vs 4x4

Recommended Posts

Does anyone know if there is a difference between the carburetors in the 2x4 vs the 4x4 models of a 1998 Big Bear 350?  I was going to purchase this carb off eBay 1997-1998-Yamaha-Big-Bear-350-Carburetor-YFM-350-2x4-Carb-ATV-YFM350 but it says only 2x4 models.

 

I don't see why the carbs would be any different but mine is a 4X4 so I don't want to put the wrong carb on.

The same seller is showing what looks like the  same  carb,  advertised as  good for  both the   2x4  and 4x4, and at the same price.  My  guess would be  the one    shown  in  your link  may have  jets optimized  for  the   2x4  model  and possibly   would result in a  lean  burn  for the  4x4 which  may  require  a  little richer  mixture for the  extra power demand of   4x4 .

Yeah it looked the same to me too but they advertise it as a 87-96 only where is mine is a 98.  I don't see the difference other than what you said about the jetting may be different on a 4x4 carb.
