Has anyone ever put 1 1/8" 389s on an 88SS?
88SS and early 650SS bikes both had 376s, but there's report of people running up to 932s on 650SSs with good results, so...
I've got sets of 389s and 376s, but wondering if the 389 would just be too big, even with a hot(ter) motor. I'll be making the inlet manifolds and sleeves for the inlet ports, so I can definitely taper everything to speed up the flow, but would rather not spend the time to make it all if there's experience out there telling me otherwise.
