i was going home "doing 75 in top gear" and the bike just died on me the back wheel did not lock up and there is not oil anywhere so i know the engine did not seize up
it did not overheat or anything
it has fuel and oil

i think one of the gears may have exploded

Are you sure its not an electrical fault?

So does it start, and just not give drive to the wheel. Or not starting at all?

i have charged the battery over night so it is fully charged and the bike is not turning over on the Ele start

Even though you charged the battery, it might not be fully charged if there is a duff cell. Have you tried bump starting it in second gear? Have you checked all the fuses and the most obvious of all, have you checked the kill switch?

think one of the gears may have exploded

What makes you think that?

Does sound electrical to me, do the dash lights appear? can you get neutral? and as he says have you tried bumping it?

all the lights work all the fuses that i can see are fine and i have had it turning over but the it wont turn over again
i have tryed bumping it in 1st and 2nd but the back wheel just locks

If its not turning over then it indicates starter system, if it does turn over and not start then spark plugs/leads would be looked at.

They may lock when bump starting as there isn't enough grip to turn the engine over.

i have just had the hr=ead and barrel of and the piston is not seized so that is good

but i have taken the front spindel of and the chain and when in gear it will not turn no matter what so i can only guess i have a exploded gear

i have also taken the starter motor of and that turns freely when not on the bike
but when its on the bike it won't turn

Change the gearbox oil and you should soon known if something has broken in there!

i have emptyed the oil and i could not see any metal bits or anything

i forgot to say i have also had a look at the starting sys and i have had the starter motor of the bike and it works fine the reason it dose not turn over is the big wheel that has the magnet in it gets stuck in one persion

ok i have got this far

the engine is not seized as i have had the barrle of and all is fine there.

the fuses are fine.

it has fuel.

the starter motor is fine as it speens once removed but dose not when on the bike.
the big wheel that has a big magnet in it gets stuck in one persion so it will not turn over.

no matter what i do the rear wheel will not turn it seems to be stuck but i know the engine has not seized so the only thing i can think of is that a gear cog has broken and the bits are now stopping the drive from turning.

i forgot to say

the piston moves freely in the barrle when you move the barrle but the piston and "rod" will not move

By the 'big wheel' do you mean the flywheel in the gearbox, where the starter links into?

Clutch problems could be the source. Suzukis won't start with clutch engaged, so that woudl anser the non starting, the wheel wouldn't spin easil;y anyway with clutch engaged. And the flywheel will not turn if the rear wheel is on the ground and clutch engaged. Check the clutch mechanism works on the gearbox when you pull the lever, then check the clutch plates?
