Just want to pick the brains of our technical wizards.
bike has been starting fine. Then today after 1 start orrible grinding noise & no starting.
Now on a car i'd lob it in gear rock it about a bit to free it & off you go.
Tried that on bike no joy. Is this a major problem or is there some cunning fix??
I've taken off what looks like some sort of dynamo & that spins freely any thoughts??

Sounds a bit like the starter clutch is slipping. Though I hope it's something simpler as that's not exactly a trivial job.
When you say "orrible grinding noise" is there any indication that the engine is being turned over? Maybe take the nearside cover off to check.
Also try bump starting it if you can find a couple of strong mates or a decent slope. Just to make sure it does run OK and that the problem is in the area of the starter nd not elsewhere.
A thought - what oil have you got in the engine? If it's a very slippery type it might make matters worse.
Good luck - Bob

Tracked noise to a black plastic box under seat, on right hand side as you face forwards. It is behind the black panel which is below the coloured side panel. The Solenoid?? Hopefully less expensive than starter motor?
ould it be a loose connection as bike started fine this morning no slipping just a nice crisp start.

Is your battery ok ? Sounds like the area of the battery you are describing - loose battery connection perhaps?
Mine is currently toasted and I get the same noise when I try and start the bike.
If you have a hill nearby try rolling down it in second with clutch in, then release the clutch to bump start.
Good luck
Dave
Ps If it is the starter it is typically the brushes that go, messy job but easy enough as long as you remember where to put everything back.

On my 900 I find that the connection from the starter solenoid to the body of the starter motor can cause poor starting. I take it apart and clean it up when the starter sounds like it is struggling as I know the brushes are in excellent condition, having checked them earlier this year. If you see any corrosion or there is any looseness at all on this connection it will seem like the starter is failing.

Problem solved, battery was flattish. Charged it up & off we go. Oh Ok mechanic suggested it but I did hook it up to the charger all by myself!!!  |

On poking around it appears an old wire not connected to anything may have been shorting across terminals. Could have been one of those Opti-thingy charger things.
