I'm looking for aftermarket engine plugs for my 2008+ Ninja 250 (race only). I'm talking about the 2 plugs in the alternator cover. I may be allowed to silicone them, but I prefer safety wire and the stock plugs are hard to drill. Here's an example of what I'm looking for.

P.S. I cross referenced the Ninja 250 part numbers with other Kawi road and off-road bikes and could not find anything that matches and is readily available.
