SumpThing is the world-famous complete kit that enables you to remove the external oil tank and oil-lines on your SOHC Honda CB750.
Instead of the original system with the external oil tank, SumpThing reroutes the oil internally into a lowered oil pan. Just like all older Honda CB’s (And 95% of all modern motorcycles) it’s making it wet-sump instead of dry-sump. Oil capacity stays the same at around 3 Quarts /2.8 liters and oil is filled thru a tappet cover. The sightglass will let you know the level.
Please check the following information before you order.
- Check your exhaust clearance as the kit, being 50mm thick, will lower the oil pan with 50mm.
- Check if this fits your machine by simply making sure it’s in the list below.
