rev abit while shiftin betwween gears. gd?

[espada]

i see alot alot of ppl always rev abit while shifting between gears especially those RXZ. is there any benefits to it? according to some of my frndz who did tat, they said tat it is to maintain the rpm for smoother transitions. true?

[redbeacon]

That method is called blipping.

 

Doing so, your friends are having the idealogy of matching the engine torque (speed) to the already spinning wheel.

 

You've got it right; the benefit would be "smoother transitions" -- a correct layman term that a lot of new birds use.

 

From my knowledge, this helps a lot during downshifting. Never heard a lot of people recommending blipping the throttle during upshifting and any benefits that this action brings.

 

Anyone care to comment?

[espada]

ic... juz to throw in 1 more question, anybody got any idea hw to prevent the loud ' tok' sound when shifting fr 1st to 2nd gear? i seems to get it which ever bike ride.

[myxilplix]

I notice alot of the 2b riders do it when blasting up and down yishun dam, no idea what they're thinking. If they want to be faster they should just do clutchless upshifts.

 

On downshifts i don't know if they're attempting to rev-match or just blipping for attention, because most of the time they let the revs fall before letting the clutch out which totally defeats the purpose.

My sentiments exactly... Seems LPPL to me...

 

 

 

[rhema83]

I only do that for downshifts on the track, nowhere else.

[ZzGaNgStErzZ]

my fren taught mi tis method last time, but not 4 any performance. is 2 act nia. peh, clutch in peh peh. up gear, peh again.

Blipping is usually used to match engine speed and road speed when downshifting from high speeds. It is to prevent rear wheel lock-up. Usually done when entering corner at high speed. Also, it allows the bike to be in the corner at high rev allowing the rider to get thru the corner and to pull out of the corner with optimum power. Especially useful for 2 strokes playing on track.

Yes, there's some benefit in blipping during downshifts for 2 strokers on the track, but bikes with bigger engine capacity are able to benefit from it the most when the rider does so.

 

Trivia: That's why one of the bike designers decided to invent the slipper clutch. Its use is targeted for those (mostly "newbies", in social talk) who are agressive to the bike's engine with every gear downshifts they make.

[espada]

hmmm...so tats hw slipper clutch comes abt. so if we blip on a bike wif slipper clutch, wil it be even better? or worse?

[UrAaYu]

Downshift the gear without using clutch?Won't spoil the gearbox?

[natgw]

yes it will. but for upshifting its not as bad.

I dont even have the time to rev a bit while changing gear leh ?

[Dos]

I have tried this blipping method, but i always ended up like what myxilplix said, letting the rev drop before disengaging the clutch, which serves no purpose to me or when i corner :/

 

I can't seem to find the correct rpm to blip at haiz.

Fact situation: All bikes have gears that are continuously meshed... all speeds. You change gears by putting a dog clutch into the correct set of spinning gears so that they connect with the output shaft.

 

No need to blip on upshift... ever... just insure that you shift whent engine RPM drops to appropriate point for next higher gear... most everyone does this automatically.

 

No real need to blip for downshift in most cases. Quick gear change on deceleration will allow close enough RPM's to change gears... like we all do every day. Blip when you are about to make aggressive gear changes... high speed, quick change to lower gear.

Once more useful tips from Strong Eagle. I'll practice that. Cleared my doubts. Thanks.

There was a bike magazine article featuring the technique of blipping. Read that it provided a comfortable ride for your pillion; that is, no more helmet collision between pillion and rider's helmets during downshifts.

 

Haven't tried it yet though...and when I pillion somebody, my passenger's helmet still hits mine when I brake or downshift. *sigh*

This is the article on blipping the throttle

On my NSR 150 dun need to blip lah. It has more of effect of making others think I'm a punk rider without any practical impact on the riding. On S4, unless I'm approaching red traffic light at fast speed and want to make rapid downshifts then sometimes got a bit of difference. Normal riding not needed, waste petrol only. Agree with strong eagle. But for litre bikes i think this method is used more practical and useful due to much stronger engine braking power.

[redbeacon]

Immense concentration is needed for blipping during braking IMO, especially when you're aiming to slow down at a planned point or to successfully stop at the red light.

 

During my 2B days, I had fellow bikers tell me that a biker like me need not try it out as this method was for experts. However, I didn't choose to believe them and gave it a go on my 2-stroker on a controlled area, and a few months later, went to try on my 400cc.

 

Fact is, this method allows for smoother gear downshifts as well as to prolong the life of the clutch plates by a fraction. Also, it's the bigger-capacity bikes that will benefit from this the most, whilst the smaller ones aren't affected a lot by rough gear downshifts.

indeed a useful article. it's more tan meets the eye to blipping.

[Powieee]

so can i say IF DONE SLOWLY it's - clutch in , rev abit , then release clutch ?

 

so engine brake will not be harsh ?

[myxilplix]

If you do it slowly, then no use because the revs drop back down before you can clutch out. Your clutch has to come out just as the rpms peak.

 

Another positive of blipping on downshifts for strokers, my personal opinion anyways, is that the added squirt of 2t into the combustion chambers helps to prevent piston seizure from engine braking/closed throttle at high rpm.

Btw is it possible to install slipper mechanism on stock bikes with normal gearbox?

If there's a slipper clutch kit for your bike model, of course. Money can do wonders.
