I always used to put grooves in the skirts of my race pistons - MY purpose was for oil retention / cooling. I did that ever since I stripped a Lacey Manx Norton engine I had and found the pistons so modified.
Welcome back! Hope the virus situation gets past all of us soon, but fear pockets of unvacinated populations will produce more variants (like the "Delta" - from India). Meanwhile, it appears some governments are slowly fine-tuning response to be both effective and less intrusive. I really like the side-fairing change on the FZR. Wondering what would cause such wear in a Honda gearbox? How many miles?
That's some serious high pressure damage. On the accel sides I assume. I don't think it is wear, more likely bad metal.
