1996 zrt 600 top end rebuild

ok to make a long story short, i had a nephew that passed away a year ago, my sister gave me his 96 zrt 6oo. my nephew took the top end off, pistons still attatched to the connecting rods. after inspecting the pistons i noticed a hair line crack in one of the pistons, so i bought all new pistons. rings wrist pins clips and top end gaskets. now my question is?? do i need to take the engine totally apart to clean out the crank case, there is a little bit of antifreeze in the case, he had paper towels under the pistons so nothing could fall down there, and plastic rapped arond top of engine.
thank you

One thing I would be concerned about is possible rust in the crank bearings from the coolant.
BTW - My condolences..........

No... a 2-stroke in a sled will have a separate oil tank. The oil pump will mix the oil with the fuel in the correct proportion. The entire engine receives lubrication when the fuel/oil mix enters the crankcase.
Hope this helps!

Some guys use rags/paper towel to soak it up....other have used a shop-vac.
Someone else will help with the torque specs!
