I am about to send off a 98 kx500 bottom end for rebuild. I am going over the parts I gathered up for the build. One part in particular I a wondering about the quality & design of is a Wiseco connecting rod kit I picked up. A few things I have found out about the kit are:
1 The top of the con rod where the piston pin passes through is about .5mm thinner then the OEM rod. In this area the Wiseco rod is about 3.94mm thick while the OEM rod is about 4.4mm thick.
2 The Wiseco rod has two offset oil holes.
3 Wiseco no longer makes this kit.
What I am wondering is the Wiseco rod gonna be a solid performer? or Will the double oil holes & .5mm thinner piston pin bearing wall be prone to failure due to not enough structural integrity surrounding the piston pin? or maybe the Wiseco rod is better because the , two oil holes lube better then one, the top of rod has no hole, the oil holes offset allow more strength in the center upper piston pin bearing wall and Wiseco's rod can use less material on the central upper ridge because its actually stronger?
Thanks for any info or opinions on this rod.
