Try the airbox pressure sensor

Re: Who should i get to fix the SV650

Pretty sure there is a guy neat Leeds who is handy with the SV but can't remember his username

Re: Who should i get to fix the SV650

YEAH...he goes by the name of Yorkie_Chris ;)

What happens if you disconnect that? It seems logical it could be something like that. Or maybe a coil breaking down under load.

If the air box pressure sensor is what is described as (intake air position sensor - IAPS) we did test that with a multimeter following the tests shown in the workshop Manual and it seemed fine, we didn't however take the bike for a run with it disconnected, but may be worth disconnecting it and trying again.

We swapped both coils over from my bike and this didn't stop the issue so I think they can be ruled out.

My pal is just about ready to throw the towel in and leave it at a main dealers really gutting to not be able to find the problem though as I got him into bikes and said if he got the same bike as me we could sort any problems out as we can swap parts :(

Also im guessing a main dealer would charge many hours labour re-checking all the things we have.

All the input so far has been very helpful!

We need to check the fuel jets still, but its starting to look a bit too "technical" for us.

Re: Who should i get to fix the SV650

An 04 pointy will not have fuel jets, they are fuel injected.

Intake air position sensor could (and I am guessing here) be related to the secondary butterflys in the intakes, they are ECU controled and rely on a sensor to tell the ecu where they are so it can adjust them as it sees fit.

Re: Who should i get to fix the SV650

Nothing like a challenge eh.
You tried dealer mode and check for codes? Any FI light while problems occur?

we have exhausted all options using our limited skill's:
Changed:

* Battery
* Spark plugs
* HT Leads And coils
* Fuel tank and pump
* Air filter
* Fit a standard can
* Checked all pipes for leaks and kinks
* Changed ecu

This has not solved the problem, so now i think we need to get someone with a better knowledge of the sv on the case.

I know there’s a few sv guru's on here and just wanted to know if there's anyone around the leeds area (willing to travel to them up to around 50mile).

If they would be willing to take a look at it i would happily give them some beer tokens for there efforts.

many thanks stephen

* its an 04 pointy.

a mate of mine had a similar problem on his cbr600 and it was the throttle valve sensor the thing that on the side of one of the carbs or if fuel injected throttle bodies with a couple of wires comeing out of it

Re: Who should i get to fix the SV650

might sound a bit daft but have you checked the vacuum spigot nipples on the throttle bodies as one may be cracked or loose?
