Question about 2008 Yamaha XT 660 Z Tenere

Starting difficulties when bike is parked outside

I have a 2008 model of the XTZ660 tenere. Since last januari it have had difficulties starting when it has been parked outside.
I´ve replaced the sparkplug after the engine was drowned with petrol for the first time. After that it started a bit better but now runs "rough" at variable speeds, like it's holding back in power.
I've checked the drive chain for worn pieces but couldn't find any. I'v cleaned out the air filter.

Anyone an idea??

Dude, forget the spark plug. Check the injection computer. Take the bike to a specialized service. Good luck and ride safe! Dragos, Romania

I've been having trouble starting my 2008 FLHRC recently...battery has plenty of power but when I go to start the bike...once I press the ignition alarm starts to flash...there's no clicki

Sounds like you have an anti-theft system interfering with your ignition. I don't have experience with that model bike or any manuals on that bike so that is the most help I can give.

Your ignition switch or starter button is stuck! Or the starter return spring is broken. I would look at the start switch to start with, sounds like it is stuck in the start position.

How long is the bike setting between when you park it and when you try to start it again? When you get ready to ride it, did you put a battery charger on it and bring the battery to a full charge?

When thinking it's getting to be time to ride, I recommend charging the battery with a charger disigned for ATV'S/motorcycles. When the battery is fully charged, take the charger off and test the battery with a load tester. If it passes the load test, attempt to start the bike. If it starts, and there is no further problems, Enjoy the ride till you park it long term again. I might suggest putting a battery tender and very slow trickle chat=rge on during storage

Hope this helps you

The bike was manufactured in October '09 to be sold as the 2010 model year. Auto dealers do the same. You can buy a 2011 Ford Mustang in September of this year, 2010.

How many miles/hours are on the bike? If it's a good amount when is the last time you tuned it up? It sounds like a fuel delivery problem starting. Most likely a fuel filter or carb jet starting to get junked up.

My bike wont start

I have the same problem and same model (2008 KTM Adventure 990 S) so injection, not carburator.
I didn't start the engine for three months. I bought a brand new battery. Lights, fuel pump and everything seemed to be ok at the first key turn. But when you try to turn it even more to definitely start the engine, ignition fails. I think the electric engine of the starter is not working properly.
I tried to start the engine driving down the slope and releasing the clutch in 2nd gear at aprox 30 km/h and it started successfully.
I left it idle until became hot (15 min aprox) and the turned it off.
however it didn't start again when trying the ignition button.
Any ideas?
