Triple manifold recommendations

[600Z]

Hi Guys,

I'm wondering if anyone has had any experience with the OER triple manifold which is the copy of the Sanyo type and how it would compare to the Harada manifold. 

Cheers,

Compare 'how' Justin?
Both will fit and make brum brum noises is that's what you are asking...?

Do you plan to use the original accelerator linkage or are you going with a cable set up, as that seems to be the difference between the two pictured?

Lol yes I know both will fit as their both for L6 engines along with the brum brum noise from triples which we all love.

Just wondering more so if anyone has used the OER and if the pedal feels smooth etc, any difference anyone might know in performance possibly eg. Port shape/length between the two. The linkage arms look better and stronger on the OER one where I have heard of the Harada ones can slip on the shaft. So just any constructive feedback I guess.

Both types use the original linkage system though yes the Harada is also available with the cable option which I wouldn't be using.

I have a cannon manifold but no linkages so by the time I get linkages to suit I'm part way there to a better manifold so I'm thinking of selling it and getting one of these just deciding on which one.

Or do I sell the sets of triple Dellorto's and just run two hsr 45's or 48's and they certainly seem to produce good power from after the guy on church doing a test between SU's, Mikuni 44's and twin 45 HSR's.

HSR's produced 22hp more than the SU's and 8hp more than the Mikuni's.

Guy on the church facebook page seems like a bit of a goose.......

He readily admits that neither the SU's or Mikuni's were tuned properly so I'd take his "comparison" with a grain of salt.

But, AFAIK, there may be fitment issues with the manifold(s) not having clearance with some types of thermostat housings.

Yes true though I have read good reports and certainly a bit different. I have a couple of sets of triple Dellorto's so I'll certainly go with them I think.

Yes I did see someone have issues with the Harada with their thermostat housing somewhere.
