If you want your Kawasaki Triple to run right then any two stroke needs a good solid crankshaft to start  with. Thats what I do. Send it to me and will disassemble and give you an exact estimate for needs and costs. I will look over the whole crank and determine what is the best recommendation for you. You then tell me what options you prefer such as seals bearings and rods as you wish. From there we do the crank for what meets your goals. Some folks use is for street ,some racing , some use premix . Then we determine which seals and which bearings.  Some want to use their own parts.

Below are pictures of typical Triple cranks I have taken apart. I find that almost all original seals have excessive clearance between the collar and lip of the seal. See the pictures below. This is what causes the power loss and hard starting. The new seals dont have these same problems. We also see wear in the metal surfaces of the rods , collars , bearings. As well as almost anything else over the years parts have improved so we can make your crank work great. This is very important to a strong smooth engine.
