After getting the head onto to the workbench, I started to disassemble it. Am I the only person that hears "no disassemble number five!!" every time I type that word?
Anyway, I got out my trusty valve spring compressor and went to work.
I love this tool, if you are working on motorcycles, I highly recommend the OTC model 4572 spring compressor.
For less that $45, it's a screaming deal and the design works in very tight spots. Well worth the cash..
That's some carbon build up for just over 10,000 miles!
