Hi Jayne, really need more info - ie what sort of starter problems? Does it:
1) Turn over but make a horrible mechanical noise from the left side of the engine or just whirr?
2) Turn over slowly, or just click from under the seat and not turn over at all?
The problem is most likely to be either the sprag clutch (1), or a flat battery and/or dodgy solenoid.
Don't like the sound of this bit, sounds like it could be a sprag problem.it grinds.
now my starter is running n wants to turn over my engine but b4 its able to it grinds. solenoid works fine, new battery, terminals tight. bike doesnt turn off anymore.
In a nutshell, the sprag is a one way clutch that allows the starter motor to drive the engine but it freewheels once the engine starts (bit like pedalling a bicycle). It's bolted to the back of the flywheel rotor, behind the left hand engine cover. Unfortunately, it can be a weak point on these bikes. As already said, if you do a search there is a lot of info on here about it and the good news is there are cheaper alternatives to the Aprilia part.what the hell is a sprag? how do i get at it n where can i pick one up at?
