Used but work great stock carburetors  I use the ski they are in about 3 times a week, it's a stock big pin 750 

Dual keihin 40 mm

Still has choke hookup

Comes with manifold but not reeds

Should work on small pin but do some research first

You get the choice of one spark arrestor

Number one is cut to fit in an x2 Kawasaki

Number two is normal nothing special but was off mikuni carbs so will need to be drilled on the base(I will do if needed)

Neither have the screens 

Local pickup available for no shipping and lower price

Ask any questions before buying
