650/X-2 experiance with pjs 650 or 700cc topends?

[anthonystempak]

I wana put a 650 or 700cc in my 650sx
My question is will it run? Will it run right with a single sbn44 along with a pjs
700cc pipe
Also is it worth the cost
Or just put a 750sx in it

What year is it, do the newer manifold swap with the bigger carb,stock pipe mod and drill the water box.... Huge jump in power and all stock parts
