New question for you guys. I found a set of CPI twins for a decent deal. What do I need to do to run these? Do I need to replace the head? Run a mix of avgas and Premium?
Thanks for the input!
run 10 to 15% race gas 110 or better with these pipes with stock head.
best bang for your buck is to put on the anti ratchet drivers, cut and clip the track. it will free up HP.
