which is the last bolt to release on the gearbox to seperate from engine ive done the 4 main bolts. does the big allen key bolt under starter have to come out. any pictures would be handy

 

yea...undo the hex bolt, and inside is a cylinder to release the cluch fork. To remove the cylinder you will need a 6mm bolt. Screw the 6mm bolt into the cylinder, and slowly pull it out. Pull the top of the clutch fork up, this will release the box from the engine..... it might take a wiggle to break the two away. See if you can jack the gearbox up a bit to get the right angle to ease it out...hope this helps...

 

cheers for that your my savior been messin around all day with it
