Gear Bound

[MO Predator Racer]

How does one know if he is gear bound?

 

[racing promotor]

Your adding teeth to the rear gear and rpm is not increasing, and if you know your normal max rpm drop on your tach it will be lower than normal.

How do you solve being gear bound? Like what do you do if you are gear bound?

 

[flattop1]

depending on the gear set .
add teeth to the driver or pull teeth from the rear gear .

 

[ColeAchey]

Take gear off the back until you start losing rpm.

How does one know if he is gear bound?

Experience mainly, having a good tach like a Mychron 5 and what to look for can help.

^ All of the above.

The engine will just stop pulling and your rate of MPH increase drops off dramatically. In drag racing terms which you're more familiar with, would be "nosing over." Just like a drag car that you want to still be "pulling" acellerating through the lights, an oval kart should still be pulling at the end of the straight.
It'll feel like you're hitting the governor at peak rpm. You're too far above the peak HP and on the downward side of the curve by 700 rpm or more.

That explanation was great. When you used the term nosing over like we do when tlaking about cars in on the top end of the track in drag racing it all made since.
