I posted some other threads about finally finding a local pump with high octane gas. Turns out I can not bear the smell of it. It gives me a similar feeling to having a sore throat and nausea. So, I was off work today and decided to make a cylinder head spacer that brings the comp ratio down to about 9.5. My hope is to run on straight 93 without too much knocking and detonation. I'm also hoping the reduced performance won't affect my riding too much. Anyone who saw me take back-to-back 5s in the novice section at Exeter RI will agree. So far, it kicks easy, runs fine, and has no leaks. It is only driveway tested at this point, but I'll be getting some practice time in before Meriden.
