You dont have to increase jet siize.You can coat lightly the piston with oil before reassemblinig,same for crank bearings.

If you use oil on the pistons, use 2-stroke oil. Otherwise that white motor rebuilding grease works xcellent. No need to soak the crank, although that wont hurt anything. Just squirt 2-stroke oil in the bearings.
