Pointy running poorly.

[timbuk21980]

Hi,

Iv got an SV650 (N) K3 2004 model. running really bad right now. its mainly just before i accelerate the bike feels like something is holding it back, it judders a little then picks up. and it has started doing the same thing when im cruising at a regular speed. its not a smooth ride at all really.

took it to a place where they looked at the throttle bodies and a load of sensors but its not helped much.

wondered if anyone else has had a similar thing happen

thanks, Tim

Did they check the intake air pressure sensor on the airbox?. Fairly common fault on that year of bike. They dont always fault code and run really rich causing similar symptoms to yours.

[timbuk21980]

yea they checked that apparently, took it back today they gonna plug it into a laptop, so will see what that brings up.

Has someone checked the spark plugs? I hope they are not jumping in with the laptop, before going over the basics? Plugs, air filter, etc. Not sure the laptop will pick up a clogged air filter. If they've all been checked then forgive me! Hopefully they'll find the fault.

[timbuk21980]

yea checked spark plugs. all the sensors have been checked, it has got a K&N filter on it which may make a difference if its not set up right, iv ordered a pipercross filter to replace it because i hear the K&N ones affect the throttle response and the pipercross ones are slightly better.

confusing stuff really

[SV650Racer]

K&N versus Pipercross no real difference and certainly wouldnt cause those symptoms unless its seriously blocked.!.

The sensor fault doesnt always show on the SDS so see if they can swop one off another bike just to try if they have one.

Also check the Throttle body balance and TPS settings.

[timbuk21980]

ok, yea good advice ill look into that then, ill post back when i find out more, thanks again

Shoulda bought a curvy ;)

[timbuk21980]

yea i am beginin to wonder.

[Milky Bar Kid]

Or better still, get a CBR600RR...lol!

Sorry, this really isn't helping...hopefully I made you smile though!

[timbuk21980]

yea it did fanx for that. i think ill be getting a bigger bike after this one. as much as i like it im 6 foot 5 and need somethin slightly larger. dont know what though

[Milky Bar Kid]

Ah, well, then the CBR600RR is not for you! I be little so it suits me! Only 5ft6 so I'm the ideal size for it!

[timbuk21980]

ah nice. ill keep lookin i think. was thinkin a honda vtr firestorm. my mates got an 04 one real nice.

[Milky Bar Kid]

VTR, nice!

[timbuk21980]

yea i thought so. one day

[Milky Bar Kid]

Awesome...right...I better stop derailing before I get shouted at by Sid..

[timbuk21980]

Ok update: the air presure sensor was checked before and that is all ok, the tps is all ok and the throttle body balance is fine also. so still no idea, ill update when iv heard back from them

Shoulda bought a curvy ;)


And be classed as "old fasioned" with an "ugly bike"....

Just out of interest, where are you taking your bike for the work?

[timbuk21980]

I normally send it to a place in East haddon, they really good but i know a guy who is a mechanic at suzuki in daventry he has got it at the moment

[speedplay]

Ah ok.

I always have a local mobile guy do my bikes for me.

Tyre changes on a sunday morning in my back garden for £30 plus the tyre... Result :)

[timbuk21980]
