gravion Posted March 7, 2012 Share Posted March 7, 2012 (edited) hello boys and girls, im keen to know about engine braking, ive tried heaps on 125cc wave, and the bike is quite able to slow down with stability, but for 650cc class when i do engine braking (shifting down) the bike wobbles hard.... i realy need to lower the speed to stabelize, but i sometimes feel really need quick engine braking and i luv da sound. so whz up? also er6n got misfiring system?? i quite frquenly hear popping sound like those rally cars.

poanoi Posted March 7, 2012 Share Posted March 7, 2012 I do engine breaking with my 1100 all the time and it is by far and away more stable than any scooter in every possible way, but it is lean running so i get backfire unless it is high rew Link to comment Share on other sites More sharing options...
BigBikeBKK Posted March 7, 2012 Share Posted March 7, 2012 do you rev match or just drop the clutch? no slipper clutch on the EX650 so if you're just dropping the clutch the back end can squirm a bit. yeah, twins pop. plugging the pair valve and installing a properly tuned fuel injection module will greatly reduce the amount of after-fire. 1 Link to comment Share on other sites More sharing options...
VocalNeal Posted March 7, 2012 Share Posted March 7, 2012 Brakes are cheaper than engines, brake with the brakes and be in the correct to exit the corner. Of course if you are a MotoGp star and want to slide into the corner Then again I am guilty as well in the past and used to purposely enter tunnels fast and snap the throttle shut same same in a Mini Cooper S Link to comment Share on other sites More sharing options...
KRS1 Posted March 7, 2012 Share Posted March 7, 2012 If i let someone ride my bike and they make the rear tire skid/chirp with engine braking...that is the last time they will ever ride my bike. Link to comment Share on other sites More sharing options...

gravion Posted March 7, 2012 Author Share Posted March 7, 2012 possibly 4000+ rpm and shifting down will cause wobble..... i tried relasing the clutch slowly, but somes wobble wooble happens... im scared, what does twin mean? i luv revving hard on 2nd 3rd gear and letting the throttle off... pop pop pop wuuunn..... brooom.....

madjbs Posted March 7, 2012 Share Posted March 7, 2012 Weird.........all you are doing is making a fool of yourself. Lets see what other FACTS of small displacement bikes you would like to argue or take as a personal insult. Usually: -They are slower -They are more unstable -They have less torque -They have less HP -They are lighter -They corner quicker -They are cheaper Take your pick? All facts, no insults.

madjbs Posted March 7, 2012 Share Posted March 7, 2012 Haha, now that is funny! I wonder if people have problems locking the rear wheels in that thing when slowing for a corner. It goes 8mph you know! Link to comment Share on other sites More sharing options...
madjbs Posted March 7, 2012 Share Posted March 7, 2012 Brakes are cheaper than engines, brake with the brakes and be in the correct to exit the corner. Of course if you are a MotoGp star and want to slide into the corner They also overheat like engines. If you are driving down a big mountain and you over use your brakes, they can overheat and you will be left with no brakes at all. Not good!

Gary A Posted March 7, 2012 Share Posted March 7, 2012 I have used engine braking on every manual transmission with a hand clutch that I ever owned. It just seems natural and certainly has never hurt any of my bikes. I do it with my manual transmission cars and trucks too. As far as I am concerned, not using gears when slowing down is the sure sign of a rookie driver. You DON'T allow the engine to go down to idle then downshift and then pop the clutch on a bike or a four wheel vehicle. The semi automatics are much more tricky downshifting because the clutch release is in the shifting pedal mechanism and downshifting is more trouble than it is worth unless going down a long hill. This is to prevent the brakes from overheating. Even my fully automatic scooter uses some engine braking all by itself. Link to comment Share on other sites More sharing options...

Correct, in UK on steep gradients there is usually a road sign saying ''Low Gear''. Link to comment Share on other sites More sharing options...

I have a BMW F650GS and a R1150GS, oh and a scoopy. The point is that you take someone stating a CBR150 is very hard to lock the back wheel in engine braking (which is a good thing, and normal on small bikes) as a personal insult. Very strange...

canuckamuck Posted March 7, 2012 Share Posted March 7, 2012 I have locked the rear while engine braking on my old CBR 150, It was fun to do, but difficult on grippier surfaces. Link to comment Share on other sites More sharing options...
madjbs Posted March 7, 2012 Share Posted March 7, 2012 (edited) that wasnt your point. I think you know what you were trying to imply My point was exactly as I said. It is not easy not lock the rear wheel of a small bike with engine braking. Anything else you think I was trying to imply is purely in your own imagination. Sounds like you are a bit sensitive on this issue... Why anyone would want to do it is a bit bewildering to me anyhow.

Daewoo Posted March 8, 2012 Share Posted March 8, 2012 I wonder if maybe you are getting two different activities mixed up... One is engine braking, which is basically the effect of the compression of the engine, in gear, throttle closed, and using that to slow the bike... the second is changing down through the gears, with our without the clutch... Engine braking is fine, in any gear, close the throttle and you should never have any break in traction on any surface... Slamming down through the gears, where the selected gear doesn't match the speed is bad news... this is somewhat softened by letting the clutch out slowly, but then you are putting unnecessary strain on the clutch... Brakes are for slowing, gears are for going... especially in a bike where the rear only does about 5% of the braking work anyway... Also, if you are loosing traction when shifting down, take note of whether you are also riding the rear brake (or if you have linked brakes)... the rear can only handle about 5% of braking duties, if you are already doing that with the rear brake, and adding more with the engine, you are looking for trouble... Cheers, Daewoo Link to comment Share on other sites More sharing options...
madjbs Posted March 8, 2012 Share Posted March 8, 2012 (edited) ^ It is the same thing, just one is a more aggressive form of it than the other. As long as the gear your are shifting down to won't red line the bike then it's fine, you might need to rev match before letting the clutch out though if you are changing down aggressively, or the back could get the wobbles.

Of course, but as per the OP, "i luv revving hard on 2nd 3rd gear and letting the throttle off... pop pop pop wuuunn..... brooom.....

WHEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEN...... broom brooom.... pop pop pop... wuuuun............. " He seems more interested in the sound show rather than the mechanics or physics, so perhaps he should just stick to the brakes and just make loud whing whing sounds as he does so.....when the machine stops he can just put another 5 baht in. The noises will probably start to annoy the others in the shopping centre though. Link to comment Share on other sites More sharing options...
