Fine sand paper or wire wool will do the job.

I believe soak them in vinegar then brush with a fine wire or toothbrush. I've never taken mine apart, but if you have all the time in the world.

If you dismantle the plugs be sure to take a photo before, else risk incorrect / mis wired reassembly!. And whilst you can clean the male connectors, you'll achieve little if the females can't be serviced (ooh!).

A mild & agitated acid bath as Lester suggested, in perhaps a cheapo ultrasonic cleaner - if you have one - might be an alternative, followed by a good wash with brake cleaner spray.

A tip for when you 'power up' first time, and assuming your fuses are nice motorcycle / Honda ones... replace them with household fuses of similar rating (eg 13A instead of 15A) ... until you sort all / any issues out.

I cant even ride the bike if it was finished, done my mod 1 awaiting to take mod 2

I have another bike which I use at the moment, just want the bike to be clean and run well and thought electrical contacts would be  good place to start to make sure of this
