Default Riding advice

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.....

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

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

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).

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!
