Welcome Syl! You'll find a ton of technical info on these forums. Lot of helpful folks on here.
If you don't already have one, I'd recommend getting a complete repair guide for your 650. Someone might have one on here in PDF format for the 2009 or you can get one on-line. This site only has up to the 2005 models: Kawasaki KVF 650 4x4 Manuals
Tradebit.com might have one available for about $15.
Those guides are really helpful for general troubleshooting and complete maintenance.
