Segun he leído tambien se utilizan en preparaciones de motores de Karting con muy buenos resultados. Tambien comentaban que serían una solución para futuras normativas anticontaminación en motores 2 tiempos, ya que necesitan la mitad de lubricación que los demás.
Estos americanos ya hacen experimentos con ellos. En este mensaje ya dicen de su buen resultado en una gg250 comerodamientos:
100:1. A diversion from the original topic, but I have to chime in on exactly that. I am (self proclaimed) Mr. Crank bearing. I've blown more crank bearings in more bikes than I care to admit. I was sponsored by a nameless company that was pushing a 100:1 oil and insisted that I run it at that ratio. I was riding a KTM 250 EXC at that time and blew a crank bearing for the first time on that bike, just days before a national ISDE qualifier. I had a replacement for the weekend and decided on the short notice, and the need to drive a long way, to just put my bars and hanguards on the bike, rejet, and ride the rest stock. It was fine, but day one the awful stock tires haunted me. A quick tire change that afternoon to some good meat and day two was better, but guess what? Yup, Mr. Crank bearing again. ON A BRAND NEW BIKE. It was unbroken in, but still, it's a two stroke. It was too lean of an oil ratio.
I've lost plenty of GG crank bearings, on one bike. It was my second GG. An EC 250. I lost three, then sold the bike, the new owner lost one just weeks after getting the bike from me, now he has a new case half and ceramic bearings. No problems since then.
At any rate, I won't be running 100:1 until GG recommends it for my next new one.
Aquí os dejo el mensaje completo. Incluso se los enseñan a Boni Geebelen o como se escriba, jefe de mecánicas 2t de gasgas y se asombra de sus resultados:
