Honda Cg125 Black Carbon deposits on Spark Plug!

Don't experiment too much.
Clean your filter and plug.
Ride bike in normal use for couple of days and check again.
Seems a bit rich mixture that could be due to less air in mixture (reason could be dirty clogged filter) or too much petrol in mixture.

If it's OK with filter removed then it's due to too much petrol.
Buy new main jet of same number and do not throw away old one at any cost. Because when filter is removed then too much air is sucked as no restrictions.

Otherwise it could be restrictive filter.
