What did you do to your bike today?

2Wheels:
Yamaha gytr power tuner
Links are all fairly worthless, just sales pitches.
The tuner allows for 9 adjustment points for fuel and 9 for timing, at throttle openings and rpm's.
The real meat of the issue for me I guess is the general mechanics of it.
Most of the comprehensive information I have found online is car oriented and eludes to F1 technology with an asterisk, and being not bound by rules of conventional "hot rodding", and that's really where I am most interested.. when the 250f is screaming along at 10k timing retard/advance would seem more critical, as the complete combustion cycle of the a/f mix takes the same amount of time to complete, but has less time to do so.
What really sparked my interest was when I first rode the bike I felt a grin inducing surge of power from mid to top much like a 2stroke 250. I then got the tuner and seized the current map from the ecu finding +15% & +18% fuel in that range and -4° & -5° timing. The timing being retarded was a surprise, as I guess I was under the misconception that the higher rpm's would necessitate the spark being advanced to give it time to combust in the proper atdc range. Also, running race fuel with a 14.5:1 piston, again, cooler burn less detonation = advance time. So, I remap back to baseline stock settings. THERES the boring, predictable non-threatening 250f powerband I'm used to. I dicked around and created a few maps how I thought they should be, but just with mild changes to start with and just wore myself out riding and didn't switch maps often enough to get a real "feel" for what what did.
I could get a high comp piston to run no eth 100 without detonation by retarding the time?
Maybe the surge of power had more to do with the + fuel and the retard was just a safety measure?
I'm fascinated by the whole idea.

Heck, I figured you being a plumber, you would be "up" on pipes. Retarded valve timing and ignition timing is more beneficial to high rpm power than low rpm power. The engine is better able to take advantages of the faster travelling sound waves that determine how your exhaust system works with your intake. Short story: the pulse that tries to cram the fresh intake pulled through the head and out the exhaust during valve overlap moves at the speed of sound "local". Retarding the timing raises exhaust temp, which raises pressure, which makes that sonic wave move faster. So you get more of the charge back in where it counts, and that increases the high rpm "fill" or increases the volumetric efficiency. Simple enough I should have figure it out myself, but I had to have someone else do that for me. Prime reason why the length of your exhaust pipe is as important as it is.

I like that they are winning at most everything, and doing it with steel frames that allow you to get to things. Everytime I work on my crf I want to ride my yz125 more.

that too, I also like that the ones I was looking at are almost entirely just for doing yee yee shit for old washed up dudes who just want to launch off rocks all day

Garlic, turmeric, ginger, ascorbic acid (vitamin C), oregano, fish oil, every day.
You'll never be sick again.
And stop listening to western medicine!
No pills!
My son and I haven't been sick in the 3-1/2 years that I have been following this regimen.
And NEVER get another shot, of any kind, unless you want to catch whatever it is that you're trying not to get.
Also, apple cider vinegar. I home remedy cured my strep throat with it.
Natural honey, cayenne, and so many others are your natural cure. Big pharma is NOT there to make you healthier. They profit from your sickness.
Turn off the TV too.

I just eat dirt and get the same results.

It is funny how many of my friends went totally holistic, and how many of them I saw contract something serious (or even faster when a family member did) and BAM were they in front of a doc for the first time in maybe 15 years. A few of them heard "just see your lawyer" and some took some treatments that have kept them alive or extended them. I guess I should call it irony. Anyway, "western medicine" it seems has taken our life expectancy to the positive side for a pretty long time. Or maybe it is just a coincidence that through all the increased exposures to cancer causing substances, a move towards being more sedentary, dirtier air, and rising obesity, that our life is as long as it is. Truly amazing coincidence that.

from age 19 to 26 I didn't miss a single race, this year I got sick of the whole racing every round and driving over 1,000 miles in a weekend to race courses I didn't necessarily have fun on, this year I'll go race an event if its one I enjoy and I have the money, so a bike thats just there for yee yee stuff makes sense.

Kinda like how some atheists get religion when they are at the end.

I saw a lot of that "natural self treatment" when I lived in Homer, the results were pretty much what you described there Andy. Just a funny coincidence.

Sadly one of my friends who always had the mindset that critical thinking made it impossible to be anything but an atheist. His son was burned badly (didn't make it). A friend of mine who did not know Turner described how he prayed and cried in the back of that ambulance, for his 19 year old son.

I sign onto lots of people and with doctors encouragement tend to over medicate. As if you were never to suffer sniffles or aches and pain. But modern medicine is pretty amazing if you ask me.

I wouldnt' change anything that I did. My week at college started late on monday because I was late getting back sunday night. I was on the road by 2 pm on Friday. Sometimes three races a weekend and sometimes two different types and one time 3 different types. I would drink myself to sleep in the truck on my way home. Hell, I loved it. After 5 years of college I had a couple of degrees, no more substantial help to race, and felt washed up and failed. I was almost 23. I had to take another look at racing. Came to Alaska thinking I could gain some perspective if "it" wasn't in my face all the time. Didn't quite work out that way, but luck put me in a situation to discover that in Anchorage Alaska, I was not even the fastest man in my neighborhood. An ex grand national champion who was hiding from racing lived about 400 yards from me. We both decided we still loved to ride. Nearly 40 years after he and I had our first conversation, we both still do.

@Naturaledge @PALMER84ONE and @Jax
We need to go have a beer with Andy.
Maybe Floyd and that pussy Steve will show up too.

Nah, I had a great time, but you do anything too much and repetition takes it's toll, I rode an old ass wr around Moab for a few days and had a blast. So not done yet, hell I'll probably be back to racing eventually, but theirs things out side of showing up to work really sore Monday morning worth doing as a hobby

Talked to not a dumbass Steve, he says he rode brand new yz450f and went home to see how much his 4cs KTM would get him as a trade in. Local dealer is having a demo day may 6th...
