Check Engine Light on S2R1K

[David Lowenstein]

Long time no post, but thought I'd seek some advice on a problem that just popped up.  Bike has been running fine (for years, and including my 200 mile ride yesterday).  Immediately after my last refuel (which was perhaps a little fuller than I intended), I noticed the check engine light stayed on with the motor running.  I did a quick inspection and noticed nothing unusual, and the bike continued to run fine for the next couple of miles home.

Questions are:

1) Could overfilling the tank have caused the light to come on and, if so, will the issue resolve itself with some riding (or perhaps by draining some fuel out of the tank)?

2) If the alignment occurrence with fueling was coincidence, and it's something else, am I reasonably safe in continuing to ride with the light on, assuming it continues to run well?

3) What are my next steps to resolving this, assuming it doesn't go off on its own?  The service manual doesn't tell me a lot.  Am I resigned to a dealer visit for diagnosis by error code?

Relevant bike details:
- '06 S2R1000
- DP ECU (Paul Smart - P/N 96517006b)
- PCIII (717-411), open airbox
- Full Zard (O2 sensor removed)
- Evap canister removed (in accordance with original DMF sticky)

Thanks for any useful input.

too full as in to the brim or too full as in flowing on the pavement?

if it overflowed I could imagine it hitting an electronic connector and causing a problem, if that were the case though I imagine it would also have had a problem in ANY wet condition and would return to normal after it dried out.

If it were too the brim the only potential problem is with vapor locking the tank, which is still unlikely.

a trip to your local dealership will allow them to put the bike on a DDS for an exact fault code.

Thanks for the reply.  To the brim - no overflow.

The closest dealer I trust is more than 90 mins away, so I was hoping to avoid that, or at least rule out the easy stuff first before making the schlep.

Other than responding to inputs from things like the O2 sensor (which I'm not even using), I don't have a good sense of specifically what feeds the Engine Light.  In general, if the bike is running well can I assume that it's safe to ride even with the light on, until I can get it to the dealer for diagnostics?  Or are there some drivers for that light that are serious enough that the bike shouldn't be operated, even if it seems to be running fine?

Thanks.  Can you point me to a link for the correct cables?  I assume it's not a standard connector.

Scroll down to the Links section and you will see the 2 parts you need for the cable.

For anyone who was dying to hear the (quasi) resolution of this issue:

After sitting for 5 days, the Check Engine light did not illuminate when I restarted the bike.  I put 500 miles on it since then, and the light stayed off and it ran fine. So I'm attributing the issue to overfilling of the tank, and will try and avoid that situation going forward.
