Ignition cut
« on: April 05, 2021, 07:26:18 PM »
For 2 days, following a magnificent ballads, my tiger 800 of 2016 between 2 and 4000tr / min is in love with small cuts which I think come from the ignition !!

At idle no symptoms, as above 4000rpm.

No fault has appeared ....

I will either think of a capricious candle, they have 30000Kms, or a partially defective pencil coil.

What is your opinion on the subject?

The original Tiger 885  had problems with the igniter coil/sensor at around 30K. Not seen it on the 800's generally, but its a possibility?. Any codes in the ecu?

The crankshaft sensor on the original triples became temperature sensitive after about 20k miles, so it would cut out (seemed like it was running out of petrol) when the engine got hot, and after cooling down for a while it would be fine. Triumph changed the sensor and the subsequent version was fine.

The way you could tell it was a crank sensor problem was that the tacho would drop to zero whenever it spluttered - if it was running out of fuel, the tacho would have remained the same. This would happen to every bike, not just the odd one, and initially when it got hot, but would gradually deteriorate.

Yep, I had that, plus failing coil, plus fuel starvation from collapsing filter, etc, etc, When it ran, it was great, but FI is soo much better, its a real shock when something plays up. Maybe coil stick then?

No fault code.

I don't have this problem with the tachometer

I replaced the 3 spark plugs, and will do a test tomorrow once the air box is reassembled because I took the opportunity to balance the 3 cylinders.

The problem is solved, it did indeed come from a capricious candle. . .  :152:

I observed them, and no visible defects !!
