    riva heads?

    Are they any good? did they come with removal able domes or not? I have a option to buy triple 46 riva mikuni carbs, riva intake with reed stuffers, and riva billet head. How do you tell what size the domes are?

    i just got a bigger picture of the heads and they do not come with separate domes. Do you add your own domes or how does that work...

    riva makes good heads with the dome size in cc's enscribed on top of dome just check with riva before you buy on availability of domes as they have stopped producing many-you will want 35cc domes for your 81 mm motor which should give you 165psi and those are the lowest psi domes riva made for their 1100 head- run 93 unlead and a little fat should be fine- let me know if you buy and i will give you jetting specs

    yeah it does.....is that the rec or limited head? He said he thought is was a riva. Does it say on top of the head? He is only asking 100 for the head. im still confused on the domes...so some heads come with separate domes and some are built in?

    It does not say anywhere on it. This was 165 PSI so I assume it was the limited one.
