I have a gpz 1100 1984 ....someone gave it to me and the cam shims are all off...my manual does not tell much about it....my shims are too tall on all intake and exhust...someone didnĀ“t do the job right and pulled all threads out on the cam covers...I need to know if all intakes are the same size shims in short clearance and and taller on the exhust....I hope some one can help me with this...thanks Robert
