Motofino Issues :/
Hey guys I've got a motofino MF50QT-6 4 stroke scoot.
As soon as I got it, I changed the oil, (Was black and filled to the BRIM.) New Spark Plug Cleaned carb (was already clean, just went in and did it anyway) Also adjusted the valves to .004 It will idle all day long, Take it out on the road, it bogs with throttle, unless you keep it at like 1/4 or so. Then if you let go of that 1/4 throttle, it kind of sticks. Almost like it has a vacuum leak or something. Any ideas? I've got some exhaust nuts on the way now, since the exhaust valve was taking a beating with a huge leak like that. |

The revs staying high or "sticking", if not the throttle cable/butterfly physically sticking, could be from running lean from an air leak. an exhaust leak can also cause it to run lean and not return to idle right away. also check the fuel supply is flowing and that the jets aren't blocked.
