Aren't standard forged rockers around 1.2/1.3? Assuming you can find a set ..

 

Minispares do these, recommended for small bore

I read Kieth’s article and wish MS did a 1.3 version. Did look at Kieth’s website - they are costly.

Rocker Arm, Forged, w/ Hardware (12G1221E)from Seven Enterprises in California.  $19 each but includes adjustment screw and locknut.

Isn’t that the same part sold by Mini Spares. Says it’s recommended for small bore engines. What about large bore?

Same ratio used on the 1275 Cooper S.

The 's'reproduction forged rocker gives about the same.liftbas the stock A+ rocker.

I am working on the s ones this year to make them.into '0' tolerance 1.28 or 1.3:1 ratio.

So the question is, I am looking at the rockers / rocker assembly to use on, or in place of, my stock Metro 1275 Rocker Assembly in the Metro A+ 1310 that I am rebuilding (Using your RS Cam, Lightened Flywheel, Stage One Kit and Stage 2 Head).

Would these Forged Rockers be ok, seems a shame no one does a complete 1.3:1 assembly (for the same price as the MiniSpares 1.5:1 High Lift.

These rockers give no more lift than the Stock sintered A+ ones, and just the same variability. The pads are also not hardened either. One of my next projexts is to re-work these to give 1.3:1 ratio.

I have a solution for you, my 1.28:1 a+ rocker set is what you need.

Buy 10 instead of 8 as occasionally a crap one turns up. I also change tappet adjusting screws after having a failure.
