WATER STAINS IN THE ENGINE

[la gran malanga]

Over time and laziness on my part my bike has accumulated water stains in between the horizontal ridges on the engine.

Any ideas as to how to remove these things?

Wash well with automotive soap, dry with a rag and after spray a bit of WD40. Should work!

Take them off and throw them in the sink with some white vinegar. The hard water calcium deposits will come right off.
