The one which looks like an engine with a propeller on the front.

It flickered on this morning for a second or two then for the next mile throttle response low down was a bit sticky and the bike was backfiring badly on a downchange.

If it's like my VW it'll be the O2 sensor, the VW handbook says stop driving immediately when this happens, the dealer says it'll be fine.

What does it mean for a Tiger ? And what are the possible reasons ?

Spent several hundred miles in the pouring rain over the weekend, so wouldn't be too surprised if this is the thing that plugs into the downpipes and has got a little dirty.

Then again I've had a permanently lit low fuel light, coupled with a high reading fuel gauge for months which the dealer has suggested could be a corroded ECU.

One answer's a squirt of WD40, the other's £150 from Triumph Ant.

Suggestions ?

It's the ECU telling you it has a problem, but it could be any of the sensors, including the O2 one. The only way to know what is to use a dealer's gameboy or a Tuneboy then cross-reference to the workshop manual.

It would be well worth disconnecting the plugs from the ECU and checking for corrosion there, and putting a bit of silicon grease around the place.

Thanks Ian,

Mechanic explained how the ECU may be corroded at my last service. He told me there's a hole in the undertray where it comes out of the mould, which is right beneath the ECU. A fair bit of road crap gets in there, causing corrosion which I can see by looking under the pillion seat.

On new bikes he always blocks that up with bath sealant, mine has a hugger but didn't have for the first 4 years of its life.

I've always found it hard to believe the ECU is causing the fule gauge problem so haev hung off coughing up for one but if the bikes going to start coughing and spluttering it's maybe time to take the plunge.

If it's not the ECU then there's always ebay....

One of the first things I did when I got my 06 was fill all the holes in the undertray with silicone. Keeps my MP3 player dry under the rear seat so I hope it does the same for the ECU.

It might be something simple like a poor connection. I had similar symptoms a year ago, and it turned out that the earth connection on the battery had become a bit loose. Since tightening it I've had no problems.

Just one thing...

When everyone talks of silicone sealant, we are talking about the stuff you squirt round the bath, shower, sinks etc ?

Or have I just embarassed myself.......

The stuff I talked about is used by the trade and comes in cartridges from Builders merchants etc but bath sealant is virtually the same stuff sold in small tubes at an inflated price!

I would recommend one make sure the "sealant" used is 100% silicone and not a lesser value. I have used GE Silicone and GE Silicone II, RTV, and a few other brand names that escape my memory at the moment. All of the 100% silicone sealants I have used last very well and take all the heat the exhaust system can dish out.

I even used some GE Silicone around the header pipes where they slip into the head on my ol' 66 BSA Hornet, and a year later the silicone was still all there in good shape--just a little sooty colored.

True if for an engine application but we're only considering blocking up holes in the mudguard. Drain sealant will do fine at about £2 for a huge cartridge.

Or, do what I did when mine was new. Stick a piece of duct tape over each hole. Mine are all still there 47000 miles later.
