Hi all,

First, please excuse that I’m posting this in English, I hope it’s ok (However, I do read German). Thing is that I have converted my Quattrini M1 60 to case reed using a Parmakit reed manifold (the one with a CR80/older, small Quattrini M1L reed). I've turned it around so the carb is pointing out through frame since the frame was already cut. My question is if anyone knows of a short, totally straight carb rubber flange that fits, or could be modified to fit the Parmakit manifold/reed cage? Does anyone for example know of a straight RD350 inlet rubber flange? As for now I’ve just shortened the inlet pipe as much as possible and I’m using the short MB connection rubber, but it would save a few millimetres to use a rubber flange instead of the metal flange plus connection rubber. Any hints or suggestions are very welcome!

 

Usually the oem motocross manifolds are strait rubber flanges. Did you try to look for a CR80 flange on google/ebay?

Thanks! Yeah, I've looked but have only found angled ones.

You´re right. The original one is angled. https://www.ebay.de/itm/rohrAufnahme-Motorrad-flexibel-anpassungsfahig-HONDA-CR80-CR-80-cross-Einlass/382703735664?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D20140117130753%26meid%3D7951d72bc23c49158469ea24dbbcf61a%26pid%3D100005%26rk%3D2%26rkt%3D3%26sd%3D192579055504%26itm%3D382703735664&_trksid=p2047675.c100005.m1851

You could also build your own by combining a flange plate with a universal rubber flange. You only need to drill and thread the holes for the ruber flange into the flange plate.

Or even better Use the original Quattrini flange. Cut the pipe part, level the surface with a file, drill and thread the holes and attach the universal rubber flange.

Thus you can even keep the original Quattrini flanges stuffer.

Thank you Brosi, really good ideas!

better you use this one:

that fits to the CR80.

the one from brosi is the one for CR250.

Danke. Wollte eigentlich nur das Bild vom originalen (alten CR80) verlinken, weil ich dachte, den hätte er sowieso. Hat wohl nicht ganz geklappt.

Vielen dank!
