Reply To: Flywheel F & R Marks and Top Dead Centre Locating – GT250R
F – marking would mean the engine is ready to check the valve clearances at the top front, however since you already have the engine apart, you can spin it to see its lowest point , then mark the flywheel to say “PLF” (Piston Low Front) and rear PLR , Korea should have done it at factory, but when i rebuild engines i don’t need the flywheel to know if the piston is up or down since i’ve already removed the heads 😉
4x bolts = around 20ft lbs and use a little bit of loctite-medium strength. (not the hard strength)
