An oil funnel that fits
The oil filler cap on my vehicle is below the air intake housing, which makes it hard to add oil to the engine without spilling. A regular funnel won’t stay in because the cam chain is just below the opening. To make it easier to add oil, I bought another oil filler cap and used a small-core saw bit to bore a hole through the cap. Then I epoxied a funnel into the oil cap and cut the neck off the funnel about a half inch below the bottom of the cap. Now I use the new cap and funnel when I add oil, which leaves both my hands free to pour. Added bonus for me: My other two vehicles are the same, so it works on them, too.
