dry sump question

9 posts in this topic

I purchased an 05 XR650R, my first machine with a dry sump. If I leave it set for a period of time, all the oil drains out of the frame and back into the crankcase. Do I need to drain the crankcase and dump the oil back into the frame before starting? If I just start it with all the oil in the crankcase, it seems it would take a while for the sump pump to push the oil up into the frame to provide oil to the main pump that provides oil for the engine. I just don't want to do any damage to the engine. Concerned about this if I let my machine set all winter and then start it up first nice day next spring. Thanks for any advice.

Nope, just start it and run it. As with any IC motor, don't run the piss out of it right after startup- get some heat into the motor first.

Don't worry about the oil issue, both the 400 and 650 have awesome reputations for longevity.

As long as you allow it to warm up properly the oil will be properly distributed when its ready to ride. Though its not a bad idea to change the oil after sitting all winter. Also its not a bear, and pigs do not hibernate, get out there and ride!!!!!!

Thanks for the info. As soon as the weather breaks, I'll get my piggy dug out, dust her off, and go see what I can tear up. Thanks again. Merry Christmas!!

Start her, let her purr at low rmp's until the motor feels warm, then let her rip!:thumbsup:

Yes, that's what every one of us does...:devil:

Does that make sense?

Sounds like there is plenty of oil in the sump pick-up to feed the engine, until oil gravity feeds back to the sump to feed the engine...and so on.:thumbsup:
