Is it easy to remove battery from malaguti phantom max 125

factory alarm or 3rd party aftermarket alarm.
the latter is hacked in so is obvious it is.
so is its horn going off, or not home you to hear it go off
im sure you meant key off drain.
and on all cars the test is super easy with 1 tool called and AMMETER.
0.050A or 50mA is the max allowed drain.
cars with 1 small lampstuck on are1000 mA.
this topic has a name car battery phantom drain
the tests are like day electric school stuff.
why not have shop find it,using said tool
or buy the tool and see the10 + postS i made here on phantom drains, (pulling fuses to find it)

either your timing is not set right (retarded not advanced) or something in your fuel system ? possible water or dirt? you said it is backfiring when you let off the throttle, makes me point to the timing being to retarded.

Try some Loctite on the threads:

The blue allows disassembly with common hand tools.
The red usually needs impact tools to undo.

Available at auto parts stores.

The crankshaft sprocket (for the primary chain) on Harley's use the red to secure the nut, as this is something you don't want coming loose on ya.

You can add for possible causes:
clogged oil filter
worn oil pump
clogged oil pump pick up
faulty oil pressure sender
very low oil level

could be that condensation formed in the ht cable/cap/coil. disconnect them and spray all their contacts with contact cleaner and see how it goes.

In the oil box. don't you know!. How shame!
