So my 2010 YZ450F oil sightglass is in an odd location. I noticed it's above the the fill plug so I called the local Yamaha dealer and asked if I should be able to see oil in the sightglass while the engine is
not running and of course he said yes which confused the hell out of me..... I figured he knew what he was talking about since his job is to sell yamahas but I'm not convinced. So what's the deal
guys?? Should I be able to see the oil level when the engine is not running and how high should it be in the sightglass while the engine is running? And what's the consequences of overfilling??
