I got the back wheel bouncing on a down change today on the way to work. I've had this before and I know what causes it. Bike never feels uncomposed but I am never sure what to do in this situation. Don't say fit a slipper clutch cos I ain't got the dosh.

I normally just ride it out until the engine and wheel speed are the same. Is this this right thing to do or should I pull the clutch in?

Advise greatfully received.

I would just say change down after you have reduced speed a little more. When the bike is boucing about, are you really in control??! I know I feel like I'm not! :(

If the bike is bouncing about - and you are happy with it, then thats fine.

As for the right protocol.....:confused:

Sounds to me that you are braking hard and changing down at the same time. By braking very hard you're putting all the weight over the front so lifting the rear too much. You may also be in too low a gear?

Try keeping in a slightly higher gear and braking a little earlier?

That's exactly what I'm doing. I've done it maybe 5 times ever, but I wanted to know what to do "if" it happens. Ride it out, clutch in???? It doesn't bother me when it happens, I just wondered if there is a correct way of dealing with it other than slow down a bit :wink: :lol:

Scoobs, if you are blipping the throttle and feeding in the clutch you should be able to stop it bouncy. Don't just dump the clutch and then you can make minor adjustments to get the rear wheel settled, matching the engine and wheel speed. I wouldn't pull the clutch fully in if it's bumping or you'll end up in more bother with no drive and braking hard. Remember to push back on the tank and keep arms a little flexible to easy the pressure off the front.

You mentioned slipper clutches, I found this weekend that you can still get the back to step out if you want :p

Sounds like you are chaging down too early. I used to do this all the time, especially in the wet. I seem to have solved it now by blipping and chaging down a bit later. hth

Blip the throttle on the down changes a little more and maybe don't go down to many gears, the SV is torque laden and so will pull cleanly from a higher gear! You don't need a slipper clutch on a road SV, not even on a 750. The thing is to not start moving about excessively or try to tip the bike in at the time the rear is bobbing, I know this sounds obvious but many people try to and end up on their a*** because they think it looks cool!

I must admit I do tend to get the back end bobbing a sliding on the 750 sometimes (rider error), as long as you have confidence in the front end and you are doing it in the right weather and road conditions it isn't to much to worry about. Try not to over work the front end!

PS It's an inline four. Apparently, they have no engine braking (or mid range). :wink:

Yep none whatsoever, so a reliable source tells me.

It's so true. My bike doesn't even get going until you get to 34'000rpm. And town riding is just a joke! :rolleyes:

I wouldn't say NO engine braking,just a lot less than a twin. Just a matter of adjusting the revs you change at as the bounce can easily spit you off. The no engine braking,when you close the throttle the bike slows down and the reason you are changing down is either to increase the braking or keep it on the boil------------------only my conception having ridden 4,3,2 and single potters which all behave differently

Scoobs just admit that you ain't got a clue, give up and stop home:p

Same here but it doesn't bother me.....just makes me grin :smt003 . I never ever dump the clutch when giving it some(as Balky mentioned).

Try braking hard, going down a few gears, rear bouncing as you chucking it in....now that gives a bigger grin :smt040

... no?

Oh well, that's my stock response out of the window then. ;)

Too much rebound damping/preload?

buy a Kwak ZX6R, did i mention they come with a slipper clutch as standard;)

+1 about keeping still-ish, like so many things if you panic it doesn't help at all.

Backing it in does look cool, it's bloody hard though, I kinda started to learn it because I was always skipping the rear in the wet, so thought hmmm here's an opportunity to entertain myself on a damp day. Didn't last long before a very near miss and skidding to a halt with my foot down. Oops. That's one better off played with off the road...

To avoid it skipping just don't let the clutch out so fast, don't see the point of a slipper clutch.

lose some weight fat boy

thats the answer
they all too scared to say it cos they think that's yer real body ..

I nearly always blip the throttle on the change down to stop this, also saves extra sudden stresses on the old chain and sprockets.

Yes IL4s do have engine braking, well a gixer thou does anyway (slipper clutch gets an easy life with me) and certainly an IL1 has hoooge engine braking (MT-03)

Are you a throttle blipper scoobs? If not, try it (clutch in, prob down gear, blip throttle, clutch out). If you are...use more revs on the blip

This was happening to me on track when braking really hard at the end a long fast straight. I was doing all the right things, blipping whilst downshifting but my instructor tailing me saw that I was skipping.

We went back to the paddock car park to learn a few tips. We practiced hard braking and stoppies so I could feel what the bike was doing and understand what was happening to the suspension and weight distribution. (It's like a high speed stoppie) During the stoppie practice I learned brake control to stop the bike going too far forward - i.e easing off just a tiny touch. The other thing was shifting my backside towards the rear of the seat under hard braking. Next time out I put it all together and it worked brilliantly.

I also learned to blip a bit more and change down a bit later. Basically my technique was a bit harsh during the downshifts.

Some good advice here. Thanks all. I am a throttle blipper and I think pretty good at matching engine speed to wheel speed but sometimes on heavy braking and downshift I get this bounce. I'll try pushing my weight back a bit next time it happens. I don't think the easing off the brakes is an option. The only reason I am braking that hard is becuase something is rushing at me very fast. :lol:

Used to get it a lot on the SV, had it once or twice on the CBR, Its just too much break combined with engine speed i think. Let the clutch out a little slower and find that point where it doesnt do it if you enjoy the sliding, if you dont enjoy the sliding, blip the throttle.

I just get um sliding however and whenever possible, wet is fun, so is WD40 accidently caught on the tyre doing it :lol:
