I am by no means a gear head. I've never really tinkered with mechanical objects. That's never been me. That said, I've taken it upon myself to learn my bike. With that in mind, I really don't have any clue with regards to what things should or shouldn't look like but I can make educated guesses. Shiny = good. Black = bad.
There's a longer story to why I had to pull the cylinder head off the block. But nonetheless, I pulled the front cylinder head cover off my SV tonight and my piston and valves looked like this.
- I don't think there's supposed be little pebbles on the piston
- I don't think the piston and valves are supposed to look like that
My questions are,
- Do my piston and valve look OK? I don't think so but this is my first time pulling this apart. I will assume the rear looks the same.
- What corrective action should be taken?
Also, what do y'all make of this spark plug?
Thanks.
