Ive had mine on and off a few times now, i found the jack handy to get the bolt out but not in , to get the bolt in i stand over the front guard facing the bike , i insert a long screw driver into the bolt hole on the gear change side of the bike, while manipulating the frame/engine buy lifting and lowering with the screwdriver i put enough pressure on the bolt being inserted from the rear brake pedal side till it pops in without forcing , works a treat for me.( my bike is placed on a centre stand to start with with the rear wheel off the ground )
