Lots of oil good. More oil better. At least in particular for small bore high revving engines.

My 300 by comparison, ridden in mid to tight areas , I'm off the gas as much as on it.

I was surprised how my 200 had virtually no ring wear. I'd replaced the piston out of guilt 3 years in, but was still at Top of tolerance.

My 07 300 I replaced piston when I bought it in 09. It was badly scoured like it had been drowned or filter leak by PO.

New piston carefully gapped ring to top end measurement, and several years later I replaced a leaking base. Rings hadn't appreciably worn.

Then, suddenly after barely 11 years of life, the left main took a shower. New rodkit while I was there. And measuring the ring was surprised as it had worn 1/3rd of its allowable tolerance. It's still in service today. Outstanding.

Golden Spectro at 40 to 1. I used it in the dirtbikes as one of my less radical small bore road racers showed little wear running it. Perhaps it got better from the 90s?
