Default Smokey Bear
Looking at a 94 big bear,runs and sounds fine. Problem is it lays down a lot of smoke. Wondering if it has to be rings or is there any vent issues that could cause a lot of smoke

There is a vent issue on some Yams. The crankcase breather exits above the air filter, condensing fumes drip onto the filter overnight and you get a cloud of smoke on startup, which then clears.
