I have an 02, 1100 V-Star Classis.
It will hold 4 qts if you change the oild filter, and approx 3.5 qts if you do not change the oil filter. If it has the factory exhaust system on it, it has to come off. If you have an after market, the front pipe has to come off to get to all the bolts that holds the cover on over the filter.
This applies to the 1100 V-Stars and hope it helps.
