I have a 87 suzuki katana 1100 and the oil case has 4300ml on the side is that how much it holds or is that the max?????? how much do i put 5 quarts sounds like a lot???????????????????????????

6 quarts will do it.
When its on the stick give the engine a quick run and check again. Especially if you changed the filter

About 4.54 quarts.

it takes about 4.2 quarts, top it off so the oil is just at the center mark of the oil level site glass in the clutch cover

look on the engine case nearest the dipstick for a "CC" designation...All quarts of oil show a "CC" measurement on their bottle...Use that designation on the engine and do the math to arrive at the capacity. You can use ANY oil you want within the correct weight ie: 15/40W. I'd recommend Shell Rotella Synthetic 15/40W about $5 qt at Walmart.
My best guess on capacity is near 1.8qts...Why not add 1.5 qts and check using the dipstick?
Good Luck

yes its air/oil cooled most of the oil cooled motors are the same not 100% sure if it will fit or if the electronics are the same

Takes 10W40 motorcycle oil, and should be about 4-4.5 quarts.

4 qts. of 10w/40, api classification sf,when you change engine oil w/ filter.

My race bike with 12.5:1 compression and a 5 degree advancer runs between 220-240 F during a race, and I have an extra oil cooler under the tail. I would not let it get over 250 F

There are several schools of thought on this. Some say you should change your oil every 3000 miles; others say every 6000 miles is fine. In any case, you should change it every 3 months.
