That's why it has a shifter....
Extending the rev limit will do absolutely nothing for you. In stock form the 106 is done making power by 5000 rpm. Reving it past there is a waste of gasoline. The bike will accelerate quicker by shifting at 4900-5000.
If you let the engine breathe (open air filter, decent mufflers, tune... some cams even... NOW you will need to extend the rev limiter because the engine is still building power out to 6000 or even 6200 rpm. When you start making power, the speed governor becomes a pain in the ass too.
No disagreement with the man. Yes a stock bike will hit 5500 in first or second pretty quick, but this is just part of riding style. If you extend your rev limiter to 6400 (Lloyd’s reprogram) it will be easier to avoid the limiter in 1-2. But honestly, you’re just being lazy now. A practiced and skilled rider would shift a stock bike at 4500-5000 to get maximum acceleration already anyway. Let that motor operate the way the designers, not the epa, intended and it’s time to extend the rev limiter.
p.s. In case you were wondering, Half Crazy is the man.
Just to show... It seems like you have no time, but you have plenty.
Notice how much time before the 1-2 shift and how far the bike travels before the 1-2 shift. This is shifting at 5800, but on a bike that is geared 7% shorter than stock and revs a whole lot quicker than stock...
See? On a stock bike you will have over 2 seconds and 70 feet of travel to get your foot under that shifter and grab second gear... no hurry.
It makes sense to remove the speed limiter if the mapping etc. has been changed. It is a stupid feeling when the machine runs well and suddenly starts stuttering at top speed. If you have to increase the rpm is up to you. I have only increased the limiter by 500 rpm. For me it is enough. According to GPS my machine now runs 210 kmh = 130,5 mph, that's enough.
