1994 kaw kdx 250

[Greenrider250]

Thanks. new to this site . Having trouble finding info on complete engine rebuild kit for my 1994 KDX 250. Does any aftermarket company offer complete kit or will I have to piece one together? Original problem...lower main bearing on connecting rod bad.

For that lower bearing you will need a connecting rod kit, and have the crank rebuilt with the new rod. I do not know of any complete rebuild kit in a box.

E-Bay? I'm not sure if this is it but I found a lot of these...http://www.ebay.com/itm/NEW-KAWASAKI-MO ... lT&vxp=mtr

The KDX250 motor is based off the 1990-1991 KX250 motor. So parts for the 1990-1991 KX250 motor should fit the KDX250. The 90-91 KX250/91-94 KDX 250 motor has a 70mm stroke vs the 92' and newer KX250 motors 72mm stroke. The 90-91 KX250/91-94 KDX 250 motor has a 1mm larger stock bore than the 92' and newer KX250. This is why you can't pick up a newer KX250 rebuild kit and put it in the KDX250.

Parts for the KDX250 are becoming harder to find. The following two companies sell engine parts for the KDX250

Wiseco: (Piston Kits) http://www.wiseco.com/ProductDetail.asp ... AppID=2765

Do you have a local motorcycle dealer or independent motorcycle shop that can rebuild your crankshaft for you? I did this recently with my KDX250 crankshaft. They installed a new Pro-X connecting rod, balanced and welded the crankshaft for roughly $200. I am piecing the rest of my bottom end and top end parts together because so far I haven't found a kit to buy all the pieces together.

Your ebay link for the connecting rod looks like a good one even if it isn't a name brand.
