2006 Aprilia RS125 failing to start

[NadiR]

Evening gents,

I have a 2006 Aprilia RS125 which I've had sat in the garage for a year. When I initially bought the bike it was running well for the first couple of months before it started to act up and kept cutting out, eventually failing to turn over.

I changed the battery which managed to get it running again, though it was very hesitant ticking over at idle, and would cut out if I didn't give it any revs. I can hear the starter motor ticking when I attempt to start the bike, but it just isn't firing up!

I know these bikes are very temperamental and I'm a complete beginner on 2 stroke Aprilia's. Any advise/ideas on where to start would be much appreciated!

I haven't had the carbs cleaned yet, I'm planning on cleaning the carbs, changing the spark plug, and putting fresh fuel & oil in. I've never gotten my hands dirty before and don't want to cock it up more than it already is so some pointers on how to get about it for a beginner would be appreciated!

Yes, the engine is turning over, but isn't firing to life. There's a whining noise that follows after the engine fails to turn over.

Thanks for all who replied! I'll definitely change the spark plug, and have a go at cleaning the carbs and report back.
