Engine Oil Level
The 800 EFI twin engine is a wet-sump engine, meaning
the oil is contained in the bottom of the crankcase. To
check the oil level:
1. Park machine on a level surface and set the parking
2. Stop the engine. Allow the oil level to settle for 3
minutes before removing the dipstick.
IMPORTANT: Do not check oil immediately after
engine operation.
3. For easier access, remove the seat the RH side panel.
4. Unlock the lever lock (A). Remove dipstick (B) and
wipe dry with a clean cloth.
5. Reinstall dipstick and push it into place. Do not lock
the dipstick.
NOTE: Make certain the dipstick is inserted all the
way into the filler tube to keep the angle and depth of
stick consistent.
When reinstalling the dipstick,
make certain to seat the lever lock.
6. Remove dipstick (C) and check to see that the oil level
is in the normal range. Add oil as indicated by the level
on the dipstick. Do not overfill. (See NOTE below!)
NOTE: Due to the dipstick entry angle into the
crankcase, the oil level will read higher on the
bottom side of the dipstick. Proper level indication
is determined on the upper side of the dipstick as it
is being removed, regardless of the level marks
being on top or on bottom. (See illustration)
NOTE: A rising oil level between checks in cool
weather driving can indicate contaminants such as
gas or moisture collecting in the crankcase. If the oil
level is over the full mark, change the oil
