I'm thinking about an ACT prolite flywheel, it is 9.5 lbs, also wondering about the weight of an stock one. thanks.

 

i don't think 1991 makes a difference haha but i just put it there anyways

 

my n/a flywheel was nearly 30lbs

 

just for future reference, if you go to the fsm in the faq section, most of these questions will be answered without making a new thread and cluttering up the forum.
but, to answer the question, i know that with my stock setup, it was 49 lbs, light flywheel, clutch, counter weight i am only at 31, but i havent measure the orc super single yet
