So I'm here at winchester bay and I saw a guy acrost the road and his R wasn't reving past mid range and I couldn't really tell what parts were on it but from what I could see (the guy had been lied to about the year of the bike) he had 86 cases and all the ignition was 86 except for the stator coils and the cdi and the coil. It had a spacer plate with a stock 86 cylinder and a esr intake and exhaust. It wouldn't rev out past mid it would bog with his set up and with my bad oem cdi and his oem bad cdi it wouldn't even start but with his 88 box ittle start and idle and has bottom end but mid and top it falls and bogs. I have bis number so I can contact him if we figure anything out.
