[QUOTE="Aasland, post: 1136264, member: 14773"] The engine was not exposed for long before I took that photo. While we're on the topic of carbon deposits, there's the head after a first-pass of gum cutter: [IMG]https://i605.photobucket.com/albums/tt134/Norskie_photos/FJR%20Forum%20Photos/P3290978-small.jpg[/IMG] The first pass removed the surface stuff; what you see above are the thicker deposits which I had to manually remove. They were particularly heavy in the squish zones. And yes .. I did on occasion redline, if only because I had to go from 1st to 3rd so I'd wring it out in 1st. For reference, here is the "new" (24k) head I didn't use ... before any attempts at cleanup: [IMG]https://i605.photobucket.com/albums/tt134/Norskie_photos/FJR%20Forum%20Photos/P3040894-small.jpg[/IMG] Not much for deposits, but an interesting tan color. This engine was from DFW, TX ... averaging 3k/year it probably sat for long periods or was ridden short distances every day. [/QUOTE]
