on/off: SV1000 vs SV650 - SV650.org

05-05-05, 01:01 PM

Talking about the annoying on/off effect common to all injected SV bikes, some people owning a SV1000 (K3-K4) state it shows less on/off than the 650 (K3-K4). Other people state tho opposite.
Anyone who rided and knows both bikes can clarify about this issue?

not noticed it myself
It might all be down to throttle control - or the lack of

No, not riden the injected 650 but have had no problems with the 1000.

A snatchy throttle is a common complaint of FI bikes, some are better than others, the SV isn't noted as being particularly poor in this respect, however the throttle is also very light so it may just be a matter of getting used to it.

If the throttles aren't balanced correctly it will feel worse.

It can also be down to the gloves you wear! Think about it. I mean only if you're having a hard time with the on/off with the throttle perhaps try a different pair of gloves, just another variable in the brain-throttle body link...

well, I'm not saying I have real problems with the throttle, but sure my SV is not so smooth at low revs as other bikes are.
However, this is a common issue of all SV (and v-twins more generally), and we already talked a lot here about this some months ago.
Coombest suggested me to adjust TPS position and so I did. Search for that interesting thread if you like. After that regulation, the on/off was reduced. Neverthless, it still reamins a bit.
Evidently, you assume it is normal cause you're used to your SV, but if you rided some other bikes you would probably undertand it is not so smooth at low speed - low revs as some others can be.
So I was curious to know whether the SV1000 was (for me surprisingly) smoother than 650 or not, since some friends told me it is, but I never had chance to ride it to make a comparison.

The problem you mention can be exaggerated when going from open to fully shut and then open again on the throttle. Often a full shut off is not needed and then the re introduction of more gas takes place a lot more smoothly. Probably is a technique question rather than looking for fixes on the bike.(For what I know of course!)

Another small contributing factor might also be the standard gearing on the SV which if you are rolling on and off in the low gears can create a touch of jerkiness.

The SV is a bit snatchy by nature. I have an older '99 650 (carburetted) and it is still a bit hard to find an intermediate position for the throttle if running slowly inside town. I've heard this is common to largish V2s in general...

..sorry, but I'm not interested in subjective opinions about SV jerkiness.
I already know my SV is much more jerky at low gas - low revs, than many other bikes I rided, so I know what I mean. We're not talking about an hypothesis, but about facts. And I also could try the 650 of a friend and his bike is exactly the same as mine (and he agrees with me, like many other people here - check old posts...).
This has nothing to do with gloves I wear, neather can be considered a good driving habit to retain throttle a bit accelerated when you're slowing down, to avoid the engine jerkiness when you re-open it...

Simply, what I'm looking for is SOMEONE who rided b>> BOTH 650 AND 1000 <<, who can tell me the difference about jerkiness, if it exists...
