2003 Suzuki VL 1500 Intruder LC fork oil capacity - Fixya

Drain the fluid and measure it, the drain plugs are at the bottom of the forks leg, then unscrew the cap at top fork tube and install the same amount of fork oil as drained out.

The fork oil should come to just below the bottom of the threads of the bolt by the o ring. do not use regular motor oil as it doesn't have the correct viscosity that fork oil has. Make sure both forks have the same amount of oil to prevent an unbalanced feel to the front end

I have a 2001 Suzuki vz800 marauder. I'm doing the front fork seals but I dont know exactly what weight I need to put in the fork. Some say 10w and some say 30w. Can you please help

Hi, all model VS 800 from1992-2000 take the same amount of oil in the front forks, using 10 weight fork oil measure into a clean measuring device or mark the side of the oil bottle 413 mls, pour this caerfully into 1 fork, and the same amount into the other fork, 413/413 cm (3)

15wt. If that is too soft, go to 20wt but 15 is manufacturers' recommendation.

According to my Suzuki service manual it states that the fork oil capacity is 11.4 U.S. oz. It also says that you must use SUZUKI Fork oil # 10. John

from the service manual pour oil in until 88ml from the top, but make sure form is fully compressed before doing so
