The Evo's lifter's roller needle bearings fall apart and this can take out the cam lobes and the oil pump's gears. I have a 2010 RG with a few mods (SE Stage 1, V&H power duels and V&H pipes) and have never been happy with the bikes power. The higher the octane number, the better able the fuel is to resist detonation. The 1/8" NPT allen head plug between the tappets has to be removed for the gauge to be installed. The two weak points being the cheap PLASTIC, cam chain tensioners, which rub against the two METAL, silent chain drives, one inboard the cam plate which drives the cams and the second, silent chain drive assembly, which is outboard the cam plate. He has an LMD that covers his back and is beginning to show signs of personality evolution (he should probably mention that to SHIELD technicians at some point, but he doesn't because what if the assholes tried to format him?). After running the engine for a few minutes, you can add plain gas to the tank and let the oil injection pump take over.
