No mot , not starting

[neil low]

Went to start the bike to take it for its mot , starter just spinning , not a chance in hell that its going to go today or any day ,think the starter clutch has gone but thats just a hunch from what i could not hear from the engine .Gah.

Can you drain the oil ? and take off the magneto casing ?

Look behind the flywheel to make sure the flywheel “sprocket” hasn’t lost any teeth too ?

[neil low]

will have a look sunday morning

[neil low]

Oil drained , covers off , no teeth missing , pressed the starter button just to see if the sprockets turned ,and they did but just spun ,so whats the next step , buy a starter clutch puller and see the state of the clutch , i have watched vids on YT and i am fairly confident in having ago , do i need the bike in gear to undo the bolt plus do i need a plate to screw into the mag holes or will a puller manage this , cheers

Plus , how do you take out the screws and centre bolt when the mag just wants to turn , they are on tight and i cant get them to budge

• Got the bolts of and the big screw but just need to get a puller now , is there a specific size puller or they all a generic size , cheers

I forgot off my head,  but is it possible you can measure the  bolt size that you took out from the center and find the thread pitch ?  – If not i will try to dig through my archives the exact puller tools Hyosung uses themselves.

You can also get a “generic” big rotor holder for bikes like harley or whatever that allows you to lock the flywheel in place  (You will need it to tighten the bolt back in after swapping the starting clutch)
