250-500cc 2004 WR250 Timing adjustment help

i have been trying to figure out how to adjust the timing on my bike i would like to try and delay it some because it seems slightly to advanced. it looks like you have to remove the flywheel what thread puller do i need? and is it straight forward like a car like a matter of rotating the assembly a degree or so? Thanks, Eric

yep just loosen the three screws' can you get too them with the fly wheel on?

the odds are after 14 years the plate will be a bit frozen
loosen the screws and give it a little love, nothing abusive as the parts are VERY fragile
if it still won't move then yes pull the flywheel

Ok I see it now and just make sure the flywheel turns clockwise so turning the ignition clockwise will delay correct?

when the flywheel is on the right the flywheel spins right or clockwise
