OSSA MAR MK1-Mounting adapter to VM26 Mikuni

Postby jcs » Wed Sep 09, 2015 11:49 am

Since several weeks I try to find the right adapter from a Mikuni VM26 to the cylinder flange (MK1) without success. Motor side the two bolts must be space of 2inch ..(I have 52 mm) and diam 32 for the carbu.

Any ideas where I can find it?

From here you can buy an adaptor flange that will allow you to use a standard Mikuni flange-to-spigot carby mount. They also sell the Mikuni carby mounts
You can see how they are made and could make your own if you are handy with metalwork

This is what your possibly chasing also, available from inmotion in the UK.

As per the above manifold that inmotion offers to suit the flanged arrangement of an Amal mk 1, this following link from Amal confirms that the 2 x mounting holes are 2 inches apart (51 mm). So I believe this is what you are seeking

Thanks David and Rod.
David I have asked the size between the 2 holes and it's 2. 3/8 so about 6cm ....too big
Rod I think I am going to order the one from In Motion that is 2 inc so 5.1 but I have 5.2/5.3 ??? why I do not know, I guess I have to get the holes bigger ....!!!
Thanks anyway, I appreciate. I have 2 bikes to restore, Ossa MAR MK1 74 and Ossa Explorer 74, so I guess I am going to ask a lot of questions

of course you can always just make a piece that has a flange to suit the barrel and a piece of pipe to match the diameter of the carby outlet, and use a piece of rubber tube to connect the two
