I've read a lot recently regarding rocker arms while looking at roller rockers for the CVH. And from what i've read the RS1600i has one hole in the rocker arms, and a slightly different ratio, and the regular S2/3i arms have two holes.

Which is this? (I can photo it from underneath too if it helps)



Also if it's a 16i rocker arm then what are they doing in my EFi head :S

 

Any info?

 

i was told the same info but cannot see any differences between the two

they all seem to have one hole

 

Looks the same as my standard efi cvh ones...

 

It showed an example in the Haynes 'Rebuilding the CVH' book i've got, and to be honest mine didn't look like the regular cvh type which is why i posted this. But since everyone else appears to have the same it mustn't be 16i stuff.

How rare are the 16i style rockers, and do they have different valves to accommodate the different ratio, or will they work fine with standard cam to give a bit more lift?

 

Every CVH head I have ever seen has had single hole rockers.
I think the single hole is the common.

 

just by looking at isnt the hole just lik an oil drain if any gets up there

 

i don't know exactly mate, jano @ Versus_Creations is a good person to ask he seems to know is rs1600i motors and how to identify the rockers from the standard ones

 

You cant tell by looking at the lifter the way it is in the pic.

You need to look at it side on, then compare with a non RS16i lifter to see the difference.

RS16i lifter has higher lift as well as being stronger in design and material.

I dont suppose you have any pictures of them next to each other?

Purely for curiosity if I'm honest.

 

tbh its info i dont really share on public forums other than my own.

Obviously my info gets on here in the end through word of mouth like above.
Best off getting it from the source..
