Engine braking after full throttle max rpm?

[Irongamer727]

So let's say you are riding your 4 stroke motorcycle and decides to go full throttle max rpm.

Would or should you ideally just let off the throttle at let's say 13-14 k rpm and just engine brake to safe speeds?

Is a 4 stroke designed to withstand that sort of strangulation? I'm personally all to used to riding 2 stroke so I'm really really scared at just letting the throttle off.

What's what?

Doesn't change a thing, of course you can use maximum engine braking. As long as you don't push your engine and stay within the safe limits there is nothing to worry about. There's a slight myth with 2-strokes saying when you are going downhill you need to brake but accelerate as well to keep oil going into the engine. That my friend is bullshit unless you're going downhill for a very long period of time.

Engine braking in general causes wear to the cylinder walls, bearings and gearbox. That's why newer cars now rev match when you down shift.

@Calum including 4 strokes?

[Irongamer727]

@Minia Yeah but my question is whether people just let off the gas after a full throttle run. Basically.

[Calum]

@Irongamer727 Well it's just natural wear and tear of the internal combustion engine. Say if you wanted to maximise the life of an engine.

I always blip the throttle regardless of whether people think it's a myth or not.

Besides, I now run premix which means no throttle, no oil.

[Irongamer727]

@Calum yeah I have always done that to my 2 smokers. Though I highly doubt it's necessary on a 4 stroke.

Nothing better than the sound of a throaty engine on overrun I do it on my 4strokes, sue me lol

[Irongamer727]

@finnerz89 Are you running carbs or injection?

[finnerz89]

@Irongamer727 injection

[Calum]

@finnerz89 I do it all the time on four strokes. Won't hurt them.

[finnerz89]

@Calum saves on pads and discs lol

[Irongamer727]

Even after redlining at 12k rpm?

[Calum]

@Irongamer727 Oil pump is driven directly off the crankshaft. So as long as the oil pump is up to the job.
