Hey guys
I want to know how do I clean the engine fins of a bike. The spaces between the find have acquired some sort of hard brown thing and I am finding it impossible to remove. I tried rubbing it with soap water and also kerosene using paint brush but in vain. What should I do now. Can I use the all purpose degreaser from Amazon by wavex? Or should I buy some heat resistant paint and paint the fins? The find are powder coated black from factory. Please help me out.
