Snappy engine

Took the K3 in to the local dealer for him to have a look at balancing the throttle bodies and FI system this morning, just picked here up with the explanation that the TP sensor required setting, bike is a lot better now with no undue slamming off of the engine when the throttle is shut off. Happy lad now as the work was done under the 3 month guarantee.

Glad you got sorted mate.

Thor, you might want to get that looked at ASAP, could turn nasty real quick.

Lean running = save petrol / kill engine
Rich running = waste petrol / save engine.

Just a thought.

Cheers Mark.

Oh totally, but I have this irritating moving issue to sort first Don't worry though, I'm not using the bike very much at the moment.

In fact, is there anything temporary that I can do to make it a bit normal (short of putting the stock can back on)? Say, taping over part of the snorkel? I simply havn't got the time to get it done properly at the moment.

Theoretically restricting the airflow should re adjust the fuel/air ratio; however the dynamics of just blocking part of the snorkel could make it run like a pig & the ECU would be working it's little butt off to correct what it see's as a problem.

Until such time as you get it remapped, I’d be cautious of high speed or distance runs, the engine running hot will also increase oil consumption, so keep an eye on that to.

Cheers Mark.

Never riden a FI model so I can't comment, but I have a carb'd K1 which exhibits exactly the same behaviour that you all seem to describe.
Very jerky and virtually impossible to ride slow and smooth in 1st.
Your right hand has to be ultra sensitive to stop the bike suddenly lurching. Takes a bit of getting used to and I can see where folks are coming from when they talk about slipping the clutch - although I conceed that you should never do this on bends as this leads to "coasting" and a serious lack of control.
Engine braking on the SV is amazing - makes your pads last miles longer.............

Thor... If the system has a removed removable baffle, get it back in for the moment, it'll give you just a little restriction and may help matters. Mine runs as rich as a rich thing with it in.

Banus, have you had the carbs balanced recently? Checked the throttle action? The crbed SV throttle can be quick but not usually snatchy as you describe.

Oh aye, some people are confusing slipping the clutch and coasting I think... One is bad- coasting leaves you basically not in full control, but slipping isn't nearly as drastic, since you still have drive.

I may go around bends like a crippled granny, but I always feel the need to slip the clucth in extremely low speed corners (10 - 15 mph) because of throttle jerkiness. If I slip it, I'm able to overcome the "jerk-zone" and still get some drive on the rear wheel. Am I screwing up or is this the right thing to do?

Sounds about right to me mate. Very slow bends and roundabouts I always use the clutch to give me more control, fine clutch and throttle control is the key!!!

Unfortunately not - it's a hindle!

Rictus - I don't do long distance or high speed often so should be ok for temps. I'll keep a check on the oil though.

Thanks to all for the help/advice.

As for slipping the clutch, I hate doing that on roundabouts because it's hard to do that and work the indicators and keep up with observation simultaneously.
