You should get also a set of clutch reinforced spring.
In case you would be interested in buy second hand perfect condition, I have a worb5 special lip cranckshaft but longstroke so you should use it either with head gasket or base gasket, but I would use it with head gasket to give the malossi a little more torque since already is very good at high rpm. It will give you more torque, boost the mid range at the cost of high rpm.I find this option better for daily and cruising use.
In case you are interested I will sell it for 80euro postage not included.
…and maybe I have also the 65 and the 21 I have to check
