Didnt notice your relativity new,
was a bit of a piss take,

Ignore it haha,
get yourself a PDF workshop manual, or join up at www.korider.com they are pretty much the Hyosung forum, they will sort you out.

try to beg borrow or steel an air gun (sometimes called a rattle gun) that will undo the nut but as has been stated earlier you will need a set of pullers, super cheap auto or repco will have a cheap set or you can hire them from hire pool etc
good luck

I wondered if someone would pick up on " Afterbirth of a Monster" reference..... HSRB87.... A flywheel is anything that stores kinetic energy..... And is critical in the balance of an engine (well one that is rideable below full noise anyway).... A magneto is also flywheel in the case of a motorcycle.

You where correct calling it a flywheel.

haha sometimes i surprise myself! it seemed logical at the time to call it that. hopefuly il get my work tool box home tomorrow and have another go.

i have acess to pullers, so hopefully that part is sorted.

then i'll have to get a replacement cog. will try dealer or is there anywhere else i could try?????

That workshop manual was all about a full engine strip.

my real question is how best to lock it up so it wont turn without damaging anything else.

You don't need to lock it up.

A carefully held spanner on the nut with a sharp rap from a hammer will often loosen the nut.

Trouble is, removing the nut is the easy part.

Getting the flywheel off the crankshaft without a suitable puller is another story.

If the carefully held spanner doesn't work out, the local garage (or if you have to, a tire shop) will get the nut off with a rattle gun no problems.

A rattle gun is good at getting stuff undone but can over tighten a nut doing it up again so you will need to be carful about that.

And its best to do it out of gear, as you don't want to damage anything else in the engine/gearbox. The rattle gun works against the inertia of the rotor and crank and jars the nut loose like the sharp rap on a carefully held spanner can, but its much easier to use a rattle gun if the nut is really tight.

When I had to take a Suzuki RGV rotor off recently I got an after market puller for it from the local bike shop, about $30 from memory. I just had to know the thread diameter and pitch of the rotor boss.

Metric thread pitch is the distance from the top of one thread to the next, if you don't have a thread gauge an easy way to work it out is to use a small rule and count the number of threads in a center meter (10mm) then divide by ten, you will probably get a number like 1 - 1.25 - 1.50 or 1.75

The rattle gun and special puller worked for me and made the job easy, with no damage.

Korider looks a likely bet for more good info ....... there may be someone there who has done this job on the same bike as yours before.

The net is a great place, a search may turn up more useful info, lots of good stuff out there.
