What's wrong with my Triumph Tiger?

One of our Facebook followers is having trouble with his Triumph Tiger 955i, so one of our experts has some friendly advice…


My 2006 Triumph Tiger 955i keeps cutting out and shuddering at speed. Could it be the coils? Fuel pump, maybe?


Yes, and probably something else other than them. The easiest repair could also be the simplest and inexpensive one and that involves looking. Check the condition of the air filter. If dirty-dirty, replace it because a blocked air filter will reduce air volume intake at speed when the engine needs it most.

Next, check the condition of each spark plug; if in doubt to their age replace all of them. Also check your fuel lines to make sure the fuel system isn’t starved at high engine rpm by a twisted/kinked fuel pipe. If your model has coils and HT (High Tension) leads, spray with WD40 – if the bike is fine with a test run then you’ll know the leads are arching to metal especially in damp conditions.

One other place you can try is the fuel filler cap. Occasionally grit and fine dust can block the cap’s air vent and cause a vacuum in the tank at high engine rpm. To quantify this, unlock the cap with a spare key while riding and during the problem experienced. Don’t try this with a full tank or open the cap wide open – it just needs to let air in.

After all this and no fix has occurred, your best bet is to go to a Triumph dealer for a system check with the official diagnostic unit. There’ll be a cost involved but it’s less time consuming.
