i've got a morini dart , looks like a tiny ducati paso ,

it is basically a 125 cagiva 2 stroke chassis where they managed to shoehorn a 350 morini engine in.
as the chassis was meant for a two stroke it does not have easy access to the engine.
to check the oil level you have to completely remove the fairing.
typical of italians ,
build beautiful things, but practicality not at the top of the priority list.
I have a Ducati Paso 907ie, and yeah, removing the body work to do anything takes about a half hour if you're careful about it. Anytime Desmo service comes up on one of my bikes I pay a shop to do it. It's ranged from 2.5hr to 6hr services. Modernish Ducatis in general are not very end user mechanic friendly, even for the Scrambler Icon 800 I owned they don't officially publish a workshop manual which was a factor in me deciding to not buy another new Ducati when the DesertX came out. That said, I replaced the clutch on my Ducati Scrambler in the garden of my apartment at the time in under an hour... watching a video of someone replacing the clutch on a Moto Guzzi V7 and I hope mine never wears out!
It's amazing how many bikes have overly difficult valve service though, take the new Royal Enfield Himalayan 450 for example, you have to pull one of the cams to adjust valve clearances. Absolute nightmare compared to something that was simple on the 411 predecessor.
A notoriously stupid design from HONDA of all brands is on the modern Cub engines up until a few years ago, the 110cc and 125cc from the early 2000s up until ~2022 depending on the model had the oil drain plug on the engine just opposite a bolt with the same head size that held the hydraulic cam chain tensioner plunger up in the engine. Come the first oil change, many people pull the wrong bolt and accidentally drop the plunger out the bottom of the engine and lose the spring inside the left hand crankcase cover which requires pulling the flywheel to retrieve it... for the latest Euro5+ engine Honda changed that plunger bolt to a button head allen/hex bolt to avoid the common mix up.
