06 YZ450F Oil level check??
Posted 30 January 2006 - 11:10 PM
The manual says to run the engine for over 3 minutes then check the oil level, and it should be between the two dip stick marks. It seems strange for the oil level to be so low after sitting over night. I thought that the oil would drain down and fill the tank and give a higher reading.
I haven't even run the thing since I got it from the dealer. Just making sure that everything is set up right before I take it for a ride on Wednesday. This low cold oil reading kinda worries me. Do I need to add oil before I fire it up. Maybe I should just drain it and refill it with the recommended quantity.

Yamahas are shipped from the factory with oil in them. Maybe not the right amount, usually too much, believe it or not.
Follow the instructions, you'll be OK.

There's nothing semi about it; it's a dry sump. The fact that the oil tank happens to be inside the engine doesn't change that fact. It still has two oil pumps, and still stores the oil supply away from the actual crankcase in an isolated (if not remotely located) reservoir. As the bike sits, the oil does what all fluids do, seek out the lowest place it can get to. It will gradually run past the feed pump shaft and into the crankcase, throwing off the reading on the dipstick. running the engine for a couple of minutes gives the return pump (which pumps oil about twice as fast as the feed) time to put it all back in the tank, so you can tell how much is actually there.
Your bike has a semi-dry sump.
