Here we go! Fuel Moto 128" upgrade

I dropped my bike off today for tomorrows appointment. Hopefully I can pick it back up on Friday. I'll do a few heat cycles and try and wait for my dyno appt. next Thursday before putting any real miles on it. Obviously I don't have a lot of faith in their dyno guy, at least as far as TTS tuning experience goes, but lots in the tech.
Nothing is ever easy in my world! :drummer:

Got my baby back yesterday! I was told the tune is a "get you buy until you take it to your tuner next week" so they only put .5 miles on it but it basically runs ok. I took it out for about a 15 mile heat cycle run yesterday, varying rpm's up to about 3500. I'll do a couple more between now and Thursday (dyno day) to get things broken in.
On another note the unrelenting 2900 rpm pinging I'd been dealing with forever seemed to be caused by an inordinate amount of carbon on top of the pistons due to oil consumption, as a few of the builders on here mentioned. A few months back I rerouted the head breathers OUT of the throttle body, so hopefully this along with new cylinders, rings and pistons does the trick. Nothing appeared to be defective or broken upon inspection.
The bike now has just over 49K on it and they say the bottom end is very strong and now the top end is brand new including having the used CNC HD heads gone through, including being decked, new valve springs, guide seals and cleaned up.

Today was the day to get my bike dyno tuned. I used Nell's 2 Wheel Dynoworks in Kirkland Wa. for the 1st time. He is no stranger to the TTS tuner system and supposedly has no issues using it. Everything went really well and I ended up with 126 HP and 147 Lb Ft of torque. Exactly in the realm of what I was expecting. When he was done he said to go home and change my oil and that the break in would then be complete.
He uses STD on all of his settings instead of the SAE that I'm used to seeing. When I questioned him about that, he explained that since we are AT sea level, here in Seattle, as opposed to 1000' or better above and our average temp is closer to 70 degrees than 80 that using the STD setting is more accurate. First I've heard of that but he's the man so no argument here.
He said that my combination of components (which I listed above) was really well put together so the job was a fairly easy one that should last a good long time with no issues. That made me feel pretty good.
The blue lines are from the tune I was sent home with from the shop.
Here is the chart;

Nells also did a final dyno run with the A/C off and found that I only lost 2 HP at above 5000 RPM's so I'm more than happy with that!
Here is a pic of my oil plug from today after all was said and done, looks great, no filings;

Nice!
Part of the build process is to do your homework and use a proven combination of parts.
Talk to a builder who has done many builds with what you are looking for. Follow their advice and expect similar results.
I followed advice from a builder who has done many big, high HP builds BUT knows how I ride and suggested a combination of parts the would fit my needs. He doesn’t do motor builds as a business but is a straight shooter.
I have a local machinist that does ALL my machine work.
A friend turned me on to a guy that does r&d dyno work for other companies and I was fortunate to have him tune for me.
Proper parts selection, good service from experts, a little more difficult than just dropping the bike off at the dealer but I believe a better product in the end. JMHO, of course but I’m happy with the outcome.
I’ve got over 5000 miles on my latest motor and smile every time I go for a ride!
THATS what it’s all about!
