hi people im warren from nireland hav had a 660 for 9years an shes still goin strong one problem lately,shes feckin about starting up.for the first time she spluttered and cut out on a recent spin its def a fuel prob ive good battery power.she has never done this to me before i eventually got going again but if i gave full throttle it would die on me so had to keep half revs in 4th gear. next day shes going like the clappers again.is this common?seen posts with similar problem is this gonna cost loads to sort out

I had a temperamental Suzuki RF600 many moons ago that didn't like getting wet. Turns out it was due to the coils being bolted onto the inside of the frame and the water ran between the tank and the frame straight onto the coils.

It would run on 3 cylinders when this happened and I had to keep it in a low gear at a constant throttle until it cleared itself.

Is the bike kept outside? Been stored for any length of time? Using a different petrol station? Changed spark plug recently? Is there a strong smell of petrol when it's not running right?

Hi Warren and welcome.

I assume your XT is a 2004 model as you've had it 9 years? Your problems sound like they might be down to a dodgy throttle position sensor - symptoms are very similar to what you describe? Was your bike ever recalled for a replacement TPS in the early days? The track could also have just simply worn out in this time. You can check its operation through dash diagnostic mode.
