Got a Zenoah two stroke with Japanese bearings. Easiest build I’ve ever done. It said high quality. I believe it, for a two stroke. It is the least smokiest engine I’ve ever used for Two stroke. I’m using synthetic, but still, very low smoke. Easy two start compared to other 2 strokes. Good quality pull start. Quieter than other two strokes, comparatively speaking. No cheap Chinese gas tank to mount and constantly adjust. No clutch cable wearing out and clutch arm to adjust constantly like the cheap Chinese ones. No motor chain to mount, adjust, or worry about breaking. Thought the tire wear would be worse than this, but not bad either, and I have cheap tires. No cheap Chinese carb back washing, leaking, and adjusting constantly. Thought I might be disappointed with less cc than the Cheap Chinese 66cc, but I AM NOT DISAPPOINTED. Very fast little engine without upgrades, especially after broke in. There are after market upgrades for these too on Dave’s Motors. Soon will get an expansion pipe. Not that I need it, but you guys know how it is. Very fast little engine. Something in my DNA had trouble getting a friction kit. There is just something about the center mount motorcycle looking bycycles, BUT I AM NOT DISAPPOINTED AT ALL WITH THIS LITTLE IT FROM Staton. Very good decision, with no regrets!
