2020 Yamaha YZF-R6 Base #f87c — RedlineX
› ‹ › 2020 Yamaha YZF-R6 Base Historique des travaux15 After 50 hours of wrenching, she's purring like a kitten - well, as much as a stroker motor can purr. The sound is richer, the power slightly more pronounced - all thanks to a custom exhaust system that's been months in the making. Just updated my build log with the correct 12:1 compression ratio spec for the pistons I'm running in my daily driver. Swapped out the old internals for a fresh short block, can't wait to see that 0-60 in under 5 seconds again. Swapped out old 9" axle for a stronger 10", now the rear end is able to handle daily driving with heavy loads without hesitation. Had to modify the throttle body adapter to fit my 92mm injectors, was a bit of a PITA, but worth it for the look. I've revised my rear differential to use 3.54:1 instead of 3.23:1 ratio for better low-end torque and smoother shifting. +3 de plus Swapped out my old 5.0 for a stroker big block, lots of work done to get it purring smoothly now. Initial drive feels great so far, plenty of power without being overwhelming. Swapped out the old transmission with a rebuilt unit, and the results are smooth like butter - no more jerking or hesitation during shifts. Swapped the pistons, now waiting on cylinder sleeves to be machined out. Should have them back soon, then it's time for head work. It took me three days to swap out the old head for a rebuilt one, with some extra TLC for the timing belt. Now we wait for break-in. +3 de plus Swapped out my old engine block for a forged unit, feels like a whole new car under the hood now. Reassembly's been a beast so far. +1 de plus Found the worn bearing on the rear main seal, fixed it with a new kit, and now the engine runs smoother than before. Almost three days of tinkering and swearing, and my trusty 350 finally hums with a sweet V8 purr. I've since updated the engine's oil cooler to the ARB 360 series after reviewing more than 500Dyno results from various builds. +2 de plus
