Amount (Per Side):
When changing oil:
VN1700J Model: Approx. 405 mL (13.7 US oz.)
VN1700K Model: Approx. 410 mL (13.9 US oz.)
After disassembly and completely dry:
VN1700J Model: 479 ±2.5 mL (16.2 ±0.085 US oz.)
VN1700K Model: 482 ±2.5 mL (16.3 ±0.085 US oz.)
Wait for about 5 minutes so that any suspended air bub-
bles can surface.
Measure the oil level, using the fork oil level gauge [A].
Special Tool - Fork Oil Level Gauge: 57001-1290
Set the gauge stopper [B] so that its lower side shows the
oil level distance specified [C].
Insert the gauge hose into the inner tube [D] and position
the stopper across the top of the inner tube [E].
Pull the handle slowly to draw out the excess oil until no
more oil comes up the hose.
If no oil is drawn out from the beginning, there is not
enough oil in the fork. Pour in some more oil, then draw
out the excess.
