What would happen if...???

Question

If you were riding a 1000cc sports bike, like lets say yama yzf 1000 and it was speed governed to 50mph,

what would happen if you gunned it FULL acelaration as if you intended to go 160mph, what would happen when you reach 50??

would it slow it down or engine crack under pressure?

what i mean is if the bike wasnt speed governed, once it reach 50 it only be a few seconds before its a 100 considering its top of range sportbike

Could it wreck the engine governed to 50mph? i dont see how the governor could hold it to 50mph at that accelaration force

thanks

Answer 1

I understand what your saying...  that the bike is accelerating at such a rate that the enertia that is generated will carry the bike over the govened speed..  but this is only dependant on the governer that is being used.. if the govner is on RPM then the bike would not allow it to exceed this rev & the engine would act as a brake to keep the bike from going over..   If however the governer was on the fuel supply then I could see the engine over reving on a lean mixture because of the enertia of the bike.....

Look at the formular 1 cars.. they are rev limited & they dont exceed the speed limit when they accelerate out of the pits....& they have better pick up than an R1 yam...

Answer 2

Some bikes have a rev limiter, so you don't over rev the engine.

Mine is adjustable, so you can set it to max out at what ever rpm.

When you hit the setting (say 6,000 rpm), the ignition starts cutting out, so you can't rev the engine over that rpm.

I guess it could be set so that the rpm's wouldn't allow it to go over 50 mph in high gear.

Answer 3

I'm a car mechanic and not a bike mechanic, but in most cases it would act the same as a rev limiter in any car.  will kind act like its surging, but will not allow you to increase speed.

I am NOT saying a governor is the same as a rev limiter, just saying the effect is similar.  

If your bike is speed governed, it will simply not allow you to go over the set speed.  it doesn't matter how much you throttle it, it just won't happen so no worries on damaging the engine....governor's were designed to protect the engine in the first place....well, and the driver lol

Answer 4

You're getting your physics a wrong.  Accelleration doesnt carry momentum as you're understanding it.  Accelleration only occurs when a force is being applied.  When a governer stops any additional power from being supplied the bike will no longer experience any increase in speed.

Answer 5

it's governed at 50 that means it can't go any faster, even if u tried pushing it to 160.

Answer 6

It'd be just like when you hit the rev limiter now - the engine just wouldn't go any quicker, and the ignition cutout will make the engine stutter.

Answer 7

The Buick Grand National Regal had a governor built into the ECM PROM that kept it from going over the speed rating of the tires, and if memory serves,it was around 130mph. It didn't sputter like a "rev limiter" but acted more like it was running out of fuel. It still ran fine at the designated speed but it just wouldn't generate any more power. It couldn't deliver any more boost to the turbo and wouldn't let the fuel system deliver any more fuel. You could purchase a performance PROM for it but it voided the warranty. The same was true with the original "Vortec" engine in the General Motors truck. We dealers were issued special seals to install on the computers in those vehicles if we had to perform warranty on the PROMs. If THAT seal was broken without documentation from an authorized dealer, the warranty was voided and it was entered immediatly into the GM system so they couldn't run to another dealer to get service.
