TPEHAK- this thread is 2 years old!
And I had to read it from the beginning to remember I started it!
Three things to report regarding this thread, after my second rebuild:
1) I would still like a Dean Adams full system but am unable to justify dumping any more money into my bike since it runs perfectly fine.
2) I do not have a wife band set up. Would love to make that mod but see reasoning of #1.
3) I do have a breather reroute. I've been running a very simple, very cheap, reroute for as long as I can remember on my bike. Only time I ever find anything coming from said breathers is a very small amount of oil vapor condensation when it rains or the temperature changes drastically.
No my valves never looked like yours. At the time of my 37k rebuild there was normal and minimal carbon build up on the bases of the valves. At the second rebuild there was nothing on the valves.
I've never seen crystallized carbon build up, or any for that matter, on my valve stems.
Hope this somehow helps.
