.....how am I (or this guy) going to get 10 more MPH on a bike that already hits the limiter in 6th gear... by leaning out the last 800 rpm?
I mean really... let's think about this: an extra 10mph --in addition- to the 190 or so my 06 does at sea level on stock gearing with a big tire on it (and it's still pulling into the limiter...). Leaning out my mixture a full point and a half would give me a 200+mph on a stock bike IF I did have the gear to get there? How much HP do you think that is that you're picking up by going lean like that? And is it honestly worth the risk/complication for a street driven vehicle that sees the limiter in 6th maybe a handful of times per year? That's just plain bullshit. Show me a dyno graph, or anything that coincides. All my graphs and real world testing show otherwise. I HAVE run it back-to-back AND on the dyno: the bike likes it fatter. It picks up 1/4mph and still pulls all the way through 6th. It sure as hell didn't pick up enough hp "in the last 800rpm" to go 10mph faster @ 190ish mph when it was lean. It didn't lose a damn bit of hp when we took it from 14.2 to 13.0... and it went faster in the 1/4 by 1-2mph at 12.5:1 vs 13:1 (dyno #'s, all those).... though I still don't know exactly why.
"The 08/09 10R with full exhaust (no PC3/V) is running pretty close to stoichiometric at WOT close to the rev limiter, and are doing GPS197mph with +1front/-1rear every day."
----show me the same run(s) with the A/F cranked down to the low 13 range and show me that it actually goes slower. I'd like to see that.
...and we're not talking about speed trials here anyway... we're talking about a good, strong, SAFE street AUTOTUNE that the guy can set his bike to and forget about. Even IF (big if here) you're right, it's about usless to this guy anyway. We can all appreciate some pedantic input/bench racing here and there, but this guy wanted some real world info... and it's just responsible to give advice to strangers with a safety margin added in. I sure don't want to be the guy that gave him the aggressive advice and he ends up fragging the top of the piston @ 170+mph because he had a bad load of pump gas. Common sense man.
