Hi all. I've had bikes, and motorcyles in the past, gave them up years ago after a work accident. Now, with gas prices climbing i'm considering motorized biking as an alternative to driving my big Ford PU around town. I'm planning to start out with something simple and reliable, like a Staton friction drive kit with a Robin Subaru four stroke engine. Has anyone here tried any molybdenum oil additives in these engines after break in to reduce friction and wear?
