Love my 04 factory but jeez she causes some heart ache.Crap rear brake yes,lost mileage from dash yes,ohlins fork seals shot yes and she only a young bike.She failed to start click click click so into repair and fitted a "Hitatchi" solenoid problem sorted starts fine now but worried now as untill i had solenoid replaced starting procedure often consisted of a loud clatter from front of engine followed by a dying wheeze and just read on forum that it could be the sprag?What is the sprag,if it goes is it major?Sorry for ignorance but have to be honest am used to Jap bikes that dont let me down,cheers for any advice.:thumbup
 
You'll hear the sprag as a graunching noise when you try to start it.
It's a bit of a pain but not too big a deal if you know one end of a spanner from another. Do a search - there's plenty of info on here (sorry, still at work and too knackered to find the links for you now) and there are cheaper alternatives to some of the pricey Aprilia parts. If it is the sprag it will have got worse quite quickly so you may be OK if it's been doing it a while.
BTW: The sprag is a one-way starter clutch on the back of the flywheel and looks like a bearing with funny shaped rollers.
Doing the sprag is part of the initiation ceremony for RSV Zone memberhship anyway:thumbup
