Hello all,

(Though I'm ashamed to admit it) I have never really done much of my own work on bikes and have relied on the garage. I'm currently on a long trip though and budget is tight, so I decided that the time was right to start learning - and I have promptly f***** things right up.

Today I changed the sparkplugs and air-filter on my 2014 Triumph Tiger 800 (basic stuff I know) - to get to the spark plugs and air-box on the Tiger, you need to remove the fuel tank.

Essentially, after replacing the spark plugs and changing the air filter, I have the following issues:

- Bike struggles to start. I have to open the throttle to get the engine running and this was not the case before, the engine always started with no issues. Once going, it seems to idle relatively normally, about 1,000rpm. The engine did not cut out during normal start/stop city riding when I took it for a short ride.

- The engine warning light is showing.

- On a short ride (40 minutes) fuel consumption seemed very high, dropping several bars on the gauge.

- All three cylinders are firing, so I don't seem to have done anything wrong with the plugs.

- I removed the airbox to clean when changing the filter - disconnecting breather pipe, snorkel, etc. When replacing the snorkel, it did not seem to fit as snugly as previously.

Would really appreciate some advice on:

- what is the likely issue and what should I try to fix it?

- am I likely to do further damage to the engine running it?

Thanks in advance for any advice!

(I'm currently in Tallinn in Estonia and will be heading to Helsinki on Monday morning - anyone in either city able to help out in person will receive a .)

So, but of an update.

Gone back and redone airbox and spark plugs. First time, I had failed to reconnect tube to the mapping sensor - doing that fixed the start issues and slow idle.

But I'm still getting an engine warning light - all connections are correct and tubes reconnected to airbox and petrol tank.

Any tips on what might be causing the engine light are welcome.

If not that, recommendations on the best, cheapest mechanics available in Helsinki...

double check any loose cables, if it was previously OK and now you have engine warning light on it has to be some sensor not connected right.

may be the warning light is for the fault you fixed and it needs clearing? Simple things sometimes work wonders. Disconnect battery count to 20 reconnect battery, it might help.

Hello all,

I know it's late but thought I would explain what the situation was.

The whole problem was just that I'd failed to reconnect a tube to the map sensor. This was causing the start issues and warning light.

What I didn't know was that the light remains on until the engine has gone through a couple of heat cycles after a problem has been resolved, so after reconnecting the tube and finding the light was stlll on, I completely dismantled the airbix and refitted the spark plugs a second time trying to find the remaining "problem" that was causing the light to stay on

Eventually learned of the light staying on on the Tiger 800 forum and sure enough, after a couple of short rides it switched off.

So, lesson learned is, when doing something for the first time, I'll write down the steps as I go and cross them off as put everythnig back together - a bit time consuming, but not as much as doing the job twice trying to find what you missed the first time.
