I have a vance and hines SSR2 exhaust on my 91 f2, I came across a v&h power pack for sale. Just wondering exactly what this does and if anyone has any experience with one on there bike? Thanks

 

ignition advancer if i'm not mistaken...

 

I came across one a while back and did some research, most people seemed to feel that unless your bike was pretty modded already, ie ignition advancer, jet kit, coils, full exhaustetc, it didn't make much of a difference

 

I think it actually requires its own special ignition advancer to be installed
