So here is the list of newbies, and people who have yet to understand. Goose, Supafly, and Solo.
I will try to explain it for the last time.
The race is 660 feet, 1/8 mile
Your motor can turn a MAX of 9000 RPM with a 200 pound rider.
Your motor only has time to turn 4100 RPM in the 660 feet.
You start off with the wrong stall at 4500 RPM.
The motor only has time to turn 8600 in the 660 feet distance. BUT you notice your motor was STILL PULLING!!!!
So you now raise your stall to 5000 RPM
Now the motor has enough time to MAX OUT on RPM turning 9000 RPM 20-30 feet before the finish line.
You have just FINE TUNED YOUR COMBO. You have gained MPH, RPM, and a quicker E.T.
Now, you can maybe understand, Goose, Solo, and Supafly.
Raising the stall helped you gain. Because your combo wasn't tuned correctly to begin with. You still CANNOT go past 9000 RPM max unless you change your gearing, motor mods, or lighter rider. FIRST you must reach your MAX. Solo NEVER reached his max, so he was still gaining speed and RPM.
Read this over and over, try to understand that I just took time out of my day to teach you guys. Any more I have to start charging.
