Your car or vehicle is in neutral, or the clutch is shot.
there is black knob on side of carbs turn clockwise to increase rpms
When you slow down in a vehicle without stepping on the brakes, the RPMs typically increase because the engine needs to work harder to maintain a consistent speed. This is due to the transmission downshifting to a lower gear to match the reduced speed of the vehicle, increasing the engine speed.
If you accelerate and the transmission shifts to a lower gear of the overdrive disengages the RPMs will increase. If the vehicle has a manual transmission a slipping clutch will cause the RPMs to increase if the clutch is defective.
640 rpms
Roughly 800 RPMS while in park and roughly 600 RPMS while in drive or reverse
cars idol speed in 640 rpms
It depends on what type of car and what gear you are in
Apporximately 1200 RPMS
my 1990 tracker runs at a little less than 3,500 rpms and it has a 1.6 backed with a 3-speed trany.
The more you push on the accelerator the more you increase the fuel/air mixture to the engine which will cause the engine to turn more RPMs, thus propelling the vehicle at a faster speed.
If by bike you mean bicycle then: Yes if you increase your speed or the intensity for that matter then your heart rate will also increase.
Initially more MPH can usually be gained with an Aftermarket Variator, which adjusts the gearing on the belt drive. 2005 and Earlier models are rev limited at 8000 rpms, 2006 models are limited to 9000 rpms. This quickly becomes the speed limiting mechanism. Third party CDI units can be used to increase the rev limiter and change the timing.
