Rattle rattle, EFI oil light HELP !

6VOLT wrote: Hi all,   I was out for a ride today with some friends and have come a cropper with the bike.   It was a spirited ride but as we were on the slow down into a village I noticed that my EFI light was on as was the oil can symbol.   when I came to a stand still I noticed that the bike sounded like crap, rattling etc.   It almost sounds like a cam chain tensioner kind of sound.   Whilst riding I noticed no drop in performance and noting that sounded out of the ordinary, but to be on the safe side I got it picked up in a van.   It's an 06RSVR with only 4,700 miles. Anything going drastically wrong at this mileage is a right sod!   Would the hydraulic cam chain tensioner cause this kind of problem and EFI/oil display?   My oil is topped right up and there are no leaks.   Thanks   Dan

The oil light and efi light are separate fault warnings. Are you sure it was not oil and triangle or efi and triangle ?

The oil light means low oil pressure which would not be good at all unless the pressure switch is goosed which is poss.  A tensioner issue would not drop overall pressure nor throw a code.

They do sound like a bag of nails when they misfire. Does the batt voltage look ok still, at full power ?

If the problem is genuine low pressure it's either pump (relief valve is part of the pump) or the crank shell bearings. The latter will show copper in the oil.

The bike will enter limp mode when the oil press is low and that makes the bike like a misfiring kangaroo above 3k. Was it doing it at idle or just when revving ?

I would be tempted to drop the oil and if it shows no bad signs, refill and run the motor up again to idle briefly and see if you can isolate the noise to an area (top of motor or bottom etc) assuming it is still there. If it's just the pressure switch the bike should sound normal at idle.

You could also check for error codes on the dash when you run it up (hold in lap button whilst keying on and keep held for about 20 secs). A pressure switch failure should show as code 48.

The relief valve is in the oil pump so it would have to come out to check. (It sits behind the clutch basket).

If it were me I would drop the oil first just to be sure there is nothing sinister. If it all looks good go for a gentle ride and see what happens.

Re the error codes you have to hold the lap button at power on for 20 sec before starting. Then start once the code window appears. If the efi light etc has gone there will be no active codes so don't expect anything unless the fault does comes back. It would have to go on a diag machine to see the stored codes.

Would be interesting to know what codes if any are stored there. Nothing worse than not knowing and wondering if it will bite again.
