Extremely interested and thanks for sharing. Don't know about the plugs Q, but on the main points they make, I am amazed and impressed. That is some difference, between say an 'ordinary' head overhaul, valves, guides, etc, and one of theirs. Sounds as if you're in for lot of fun, and better performance all round. You deserve it, because I suspect this was not a cheap option. As for making 2 degree changes to ignition timing, good luck on that too - without taking off the primary case or the timing cover and rigging up a degree disc, and without a very sensitive meter to measure the resistance across the points in the mag to get the point of 'break' with ultra precision (or figuring out how to get a strobe on the thing) that could be a challenge. Be fascinated to hear how you get on, as I'm sure a lot of folks will be. Think I'm envious!
I do agree with the retorquing though, per previous threads here, although it may be a bit over the top! It's just a peace of mind thing with me.
