Re: 100:1 Mix
Goat Herder's article explains what happened to my CAG bike engine. When I use Opti-2, it will be only at 40:1 to keep the engine from overheating and locking up. And yes, my plug was tan and run only on Opti-2 at 72:1. At the manufacturer's recommended ratio it is a good breakin oil to get the eutectic benefit. Then switch to something cheaper.
