212 predator mods .

[Claydawg]

I am modifying my 212 . I'm thinking about modifying the rockers on a stock 212 . Is 1.2.1 or 1.3.1 rockers better . I have 24mm round slide carb . A header with 18lb springs . How does 1.3.1 with 26lb springs sound . Gov has been deleted.

Do ratio rockers require different pushrods?

1.2 is probably safer than 1.3 for piston to valve clearance problems. You didn't mention anything about changing to a billet flywheel and rod. That is pretty darn important considering the mods you are doing.

That's why Pancho said the words flywheel and rod. Do them first.

Longer pushrods are not generally needed when changing rocker ratios.
