    Thanks for the pictures. Standard 3 cylinder, FT/FR and 31M. Do you have any of the FT/FR or 31M ones for sale and if so would you ship to Australia and do you have a purchase price. You may contact me by E-Mail sjmedaris@Hotmail.com

    Some years ago I had some casted from a plug that I made modelled off the 5 X 5 31M manifold being solid without the cut outs and with the reed opening reduced to take the 4 X 4 reed blocks. I still have the casting plug and can have some casted up if required. These would require machining to the required measurements. I do not have a price, but the foundry that I use quotes $30 AU for set up and $7 AU per kilo. I will try and post a picture if I can. I think that I have one but if I am unable to post a picture here send me an E-Mail and I will take a picture using the phone and E-Mail it to you. Would not be able to do this until the weekend as it is at my sisters place.

    Email sent, did you ever do a straight in crankcase as I have seen a photo of a non factory one I think 850 had it in Tassie

    Got your E-Mail. Regarding the straight in crankcase, I played around a bit with having a pattern taken off the genuine 31M straight front and cutting it to fit a standard 3 cylinder crankcase. That was over 20 years ago. Did not precede with it as I retired shortly afterwards. There is a bit of machining required. Basically describing it is one casting which takes the inlet manifold and 3 legs that take the reed cages opening. The legs are cut to the shape of the standard 3 cylinder crankcase and the crankcase cut to take the legs. These are then welded and excess material removed and reshaped. That was the intention but the project was never finished or continued with. I still have the casting moulds and I think that I may still have I somewhere in my sisters garage. I will send a picture to you over the weekend. 850 in Tassie got his Mod 50 motor from overseas and in the late 80's early 90,s a few guys in northern NSW and Qld played around with manufacturing a couple of straight fronts but then purchase the genuine item. If it was 850cc racer, the thread that it would have appeared on would have been ""My 850 Kilo Motor""

    I dont think Cees had moulds/dies for much just drawings as I know Seaway has had to make stuff from drawings
    Tons of stuff from 2nd Effort was crushed and not shipped to Cees says our Kiwi mate Philmyrna that worked there.
    He seems to be MIA I hope he is ok?
