Blipping

[axe]

How and when do u blip the throttle

[James Deuce]

On the way down the box, to match engine rpm with the gearbox and driveline to stop the back wheel from locking up. It also stops a big chunk of your maximum potential horsepower from being delivered in a big bang to the driveline and gearbox.

Done right it sounds cool.

[ZeroIndex]

I've never actually thought about it.. it just "happens".. um, listen to a bike race, or even cars, when they shift down.. and immitate them :D

[cowboyz]

to be honest, on a 170 I doubt the engine braking will be enough to lock up the back wheel. On bigger bikes, especially in the wet it becomes nessacessary (sp?). Dont do it in every gear or it just sounds stupid. Nicely timed and it sounds cool and gets the odd boyracer reved up.

I was going into town yesterday and coming up to the lights I have it a bit of a blip. Not a lot. Just enough to satisfy my ears. Then this boyracer in a supra came up beside me hitting redline in every gear. Sounded very ghey.

[Motu]

Lot's of blipping,higher each time just before a burnout.

As Jim says, but it's even more important on a four stroke single or twin. And it does impress the car diivers so.

Remember the good old two stroke days and stamping down through the gears. It was a hell of a shock when I got my first XL and realised that you couldn't 'coast' along on a closed throttle.

[Mr. Peanut]

I tend to do it when I see old ladies, young children , or hot chicks:laugh:
Cut pipes and a drilled airbox, need I say more - BAPPPPPMmmmmm ring dinga put dinga dinga PPUT BAAAAAAAAPPP!!!!!!! :headbang:
Ixion will know what im talking about...

[Two Smoker]

Why is that??? He should do it on every downchange so it becomes natural...

I do blipping because it makes riding far smoother, gearchanges faster and less wear on the clutch and driveline/gearbox...

[bugjuice]

ditto..
i blip when changing down, just makes the ride smoother like 2S said, regardless if i use the clutch or not..

[Hitcher]

I never got the hang of "blipping". I just use a combination of clutch and throttle and "feel" for the change. Too much time spent driving trucks and heavy machinery, I guess.

[sAsLEX]

Especially with the overrun burble or whatever you call it!

Must fix the air leak in my exhaust :headbang:

[Motu]

In '70's speak - drawback!!

[sugilite]

I'm with Hitcher, I don't do it and never have. I just feel out the clutch and match revs with the throttle.

Even in racing I think of blipping as an added distraction.

In my humble opinion, blipping the throttle being smoother and easier is poppy cock.
I don't remember locking up the back whilst slithering around a damp/wet track on my high compression slick shod Superbike at Manfield on the Weekend?

[madboy]

The only appropriate time to blip the throttle is if you've got a big pipe and there's hot chicks wanting a piece of it.

Personally I use it with my soft pipe and no one wanting any of it, but then that's just me.

Your wrong, I've never thought about it on a bike(I dont change down hard often), But thats how you change down hard in a car (if you dont you shoulnt be driving). Theres no real excuse not to.

The way I was told was, there are two speeds you have to match when chainging gear, gearbox and engine (rpm) let the rpm drop a bit when changing up and increase the rpm when changing down.

I dont bother when Im just crusing around because there isnt that much stress on either the engine or the box/driveline to make any differance apart from being fractionally smoother.

[Edbear]

Especially when I'm coming home from a ride and changing down as I approach my driveway to let the wife know I'm home safe, and then before switching off in the garage to emphasise the fact, just in case she didn't hear!:ride:

it did lock up once in the wet for half a second (i forgot once), but it sounds cool (my bike has a lot of back-fire type sounds coming out of it) and on monday it will sound even better - new exhaust

[vtec]

I do it all the time. I keep only two finger's on the brake, cause that's all I need to pull stoppies on my CBR (when the brakes are working properly). Having the other two fingers on the throttle help me control the revs when I'm on the brakes. Just be careful not to give it forward drive when you are slowing down ultra fast. If you don't do it when you are hard on the anchors, you will lose the back end, because there is no weight on the rear wheel for it to have enough traction to bring the engine up to speed.

What sugilite is doing is really the same thing, matching the engine speed with the gearbox is what people mean when they say blipping the throttle. Only it's a more controlled blip when you get that good at it.

So how's the double clutching work on a bike then????!!!!!

[Eurodave]

but it's even more important on a four stroke single or twin.

Hell yeah!!,blipping down through the gears & listening to the throaty overrun on my Conti 'mufflered' '74 Guzzi 750-S is definately one of lifes pleasures!!:Punk:

[vtec]

So how's the double clutching work on a bike then????!!!!!

I'm pretty sure that double clutching, is where you go to launch off the line, but your revs get pulled down too far by giving it too much clutch. So you pull the clutch in a bit to lift the revs. It's like taking two goes at launching your bike if you don't get it right first time. If done quickly, it can salvage a good launch. But will never be as good/quick as getting it right with one clutch movement.

[Hitcher]

Hasn't your bike got an H-gate shifter?

[Smorg]

i try and blip on my mountain bike but it ends up sounding gay......so i dont bother

Conclusive proof that gears are for queers.

[ManDownUnder]

It's one of those things - you think about doing it and you'll get it wrong... practice it then forget it and it's easy...

That may be one usage of the term. However, I have usually heard "double clutching" or "double declutching" used to refer to the change technique used on non syncromesh gearboxes (eg those fitted to trucks or heavy machinery, as per the original reference). I think this was the meaning intended

The clutch is disengaged, the gearlever moved to neutral, the clutch engaged again, the throttle blipped and the clutch disengaged again to allow the gear lever to move to the new, lower gear. But much quicker than that. On normal bikes it will not work because we do not have a H shift, hence we cannot move from (say) fifth to neutral. And the wet clutch allows enough drag that it is unnecessary.

However, on the BMW, with its dry clutch I do indeed double declutch for the second to first shift . It works

[cowboyz]

You only *need* to do it when coming through the gears hard. With every bike I have ridden the gearboxs are so close together you don't need to blip the throttle on every second gear. And it loses the cool value and sounds very boyracerist. Nicely timed through 4 to 3 or 3 to 2 and it sounds cool and will get you some looks. I don't blip the throttle ever going from 6 to 5. rarely from 5 to 4. 4 to 3 and 3 to 2 are common. Never actually get to 1 till stopped.

Yeah that's what double clutchin' is, vtec's got it crossed up, trying to manually match cog speeds because otherwise they'll mince themselves. Synchro's are a fantastic thing.

Many a ricer does it on the way up too for some bizarre reason, but I find it easier to just slip it out of gear without the clutch, then put the clutch in as you drop it into the next one. Can get on a good flow of nudging levers and pedals for well speedy changes.

But generally it refers to the way down.

[Motu]

The way I got shown how to double de clutch when I was driving old British trucks like Leylands,Albions and Atkinsons - was,in the neutral part of the shift I'd move the lever gently into gear until the dogs just started touching (no neutral detents),you could feel the gears slowing down,and when it ''felt'' right,you'd plop it into gear,sometimes we didn't even bother with the clutch,sometimes you couldn't.

I did the same on my old singles and the slow shifting XLV750 - gently moved the lever until I could feel the gears slowing to the same speed.On a down shift sometimes I don't blip - just raise the revs to the appropriat speed and drop it in.For use with slow riders only....

Blip on the upshift was for twinsticks - changing up on the main box,down on the aux.

Good explanation Ixion.
Yeah was indeed tweaking the nipple!
However interesting method on the downshift for the BMW.

[kiwisfly]

Hasn't your bike got an H-gate shifter?
Naa, ripped it out for a dragstrip type crash box.
1st to 5th gear in 3 meters...then the bike falls over through a lack of momentum!!!!!

[vtec]

So I'm trying to write a smart arse response but my eyes are full of tears of laughter...ahh bless ya!:killingme :killingme :killingme What's wrong with my description... it's more relevant to the world today. And having two goes at the clutch on the launch does match the term double clutching. Not capable of a smart arse response? Doesn't sound like you're capable of understanding the perspective of a far superior intellect either :stupid:

[vtec]

I think it may have been addressed earlier in this thread.

[N4CR]

Open the throttle breifly... 'bwap' sound on most nice sounding bikes. Do it when you shift down to match revs instead of letting clutch adjust engine speed (engine braking as such).

Helps stop the arse coming out on the corro loop jumping 3>2 or 2>1 on mine when you forget just how sharp that 35k corner is ;)

[jonbuoy]

I always blip if I'm changing down, not round town or at low speeds or it does sound a bit try hard.

Keeping upward pressure on the lever on first to second shifts (or all shifts if you like), till after the clutch is fully released is a kind thing to do to your gearbox as well so I was told. I've never had a false neutral since.

[bert_is_evil]

Do you blip the throttle before the clutch is fully released or as you release it?

[jonbuoy]

I do it on releasing it just before it starts to bite again, I think the idea is just to keep the revs up a bit, just so its not on idle when you release the clutch. Stops that lurching feeling as the engine isn't being sped up by the bike motion. Depends on the bike and type of riding youre doing. Some bikes seem to have bigger "gaps" in the gearing. Don't need to if you gotta supercool slipper clutch.

[bert_is_evil]

Thanks! Wasn't sure I was doing it correctly or just ending up looking like a try hard

[sugilite]

Your wrong, I've never thought about it on a bike(I dont change down hard often), But thats how you change down hard in a car (if you dont you shoulnt be driving). Theres no real excuse not to.

I must have performed a miracle last Sunday then. As mentioned I raced my high compression superbike, (comp is so high, the motor wants to overheat if on idle for longer than a minute after a race or 2 minutes before a race!) the race conditions went from dry to wet through the race, I was on slicks.
Only oil or ice could be added to that scenario to make it any slipperier, oh wait, thats right the track was slippery from oil dropped by a car on the Friday!

My point is, I did not blip the throttle, not even once. I was braking hard so the back end was light, this combined with slicks, a wet cold track is a good test to find if NOT blipping the throttle is going to cause problems.

Not even once did the back try and lock up, even at the end of the frount straight where I was going from 6th down to second. I don't think I can be accused of riding like a nana, because I won the race.

Again, blipping the throttle being a MUST to be smooth? Poppycock!
:mega: Don't believe the myth!

[Kendog]

That's a good piece of advice,Thanks. I'm a shocker at bunging it into neutral between first and second, reving the shit out of it and only slowing down! (Highly embarressing, especially when dragging off the little boy-racer boyz! LOL)

But you eased the clutch out and bought the revs up to match the wheel?

Just a diff way of doing it really.

I flip my gearboxes now so upshifts have you standing on the lever, well putting downward pressure on it, now upchanges just involve putting preuure on the lever and backing off the throttle slightly and the next gear just clicks in.

[ZeroIndex]

my new work bike (Honda CT100X) needs blipping on the gears, since it's clutchless.. when you get it exact, it sounds pretty good..

Ah racers do that for tipped over gearchanges as well I think. Wouldn't wanna get mixed up when you jump on your road bike he he.

And this is why im investing the thousand odd bucks to get a slipper clutch --so I dont have to blipp no more (the zxr750 has a factory slipper clutch )
For those that dont know slipper clutches make it possible to down shift heaps and NOT lock the back wheel up

[Motu]

You could just get a 2 stroke...no locking the back wheel and more power to boot....

[Mr. Peanut]

:stupid:

Two-strokes are the shizz,

I just hope they don't get a bad image from all the newbies on their learners licence...

Wait a sec :mellow:

Funny how they think two-strokes are dead, I could build an NSR from scratch using aftermarket or replicated parts.

[Ixion]

Phoebe will lock the rear wheel with a clumsy 2nd to 1st change.

[Mr. Peanut]

Jesus Ixion,

jeeesh, some of you guys are ruining this experience for me.... I only bought a V-twin and put a c/f pipe on it so I could blip on the down changes and sound cool :headbang:

What model ZXR750 comes out with a slipper clutch? I thought only the kawasaki 600 and 636 + ZX10R had those?
The bike I was reffering to with slicks was the ZX9R.

The only slipper clutch my 750 has only seems to work when the power/revs rise :laugh:

[Mr. Peanut]

:bleh: I have a dry clutch :headbang: try slipping that XD
Rattle rattle....

[FROSTY]

Sug- You are kidding me right??

[Felicks]

Two things. From memory my bike has a slipper clutch. And if thats the case then while it may be good on the down change beware when chopping into first gear hard under brakes like approaching a sharp 180 turn. Despite the slipper clutch I still have had the back wheel start to slide because of engine braking on occassions.

The other thing, does blipping actually help the gears to get up to correct speeds for changing? As the synchros do that, I was wondering if speeding everything thing up in the gear box during a blip may possibly work the synchros even harder. True or false??

[Ixion]

Motorcycle gearboxes do not have synchros.

[Grizz]

I'm with you Marknz, IMO theres no better sound than a twin. Axe check out the 'arriving' file to hear how good a twin sounds blipping down through the gears.

[Storm]

Well, I have a 350 single four and I dont always blip downwards , but when I do, I will be the first to admit, the sound it makes does indeed give me my jollies :D:D:D:D:D
Then again, sometimes I let the engine burble and backfire just to hear it as well, so maybe I'm not the most responsible rider out there :bleh:

[Gazman]

What's blipping?

[Felicks]

Oh, wasn't aware. That being the case and the sequential thing aside, how do they change/survive without spitting teeth all over the road? Or is that too difficult to answer without boring everyone else in this thread - except me?

[Ixion]

Dog clutches. The gears are constant mesh, with dog clutches to engage the one desired. Like Frazer-Nash.
