Now however I cannot get onto the "Realclassic" site to write down the specifications/jetting/and conversion process and would like a bit of help from all/any of you in this area.
My BVF carb is quite worn (the slide can be "rattled" from side to side within the carb), and occasionally sticks and does not return the carb to "off'''.
So I am looking at using a Mikuni. Which Mikuni model has the spigot mounting (so that I can use the existing manifold)? Can anyone supply pictures of changes to both the manifold and the air box connections?.
Many thanks, Arthur
Hi Arthur
The spiggot mounting model is: VM30-83 30mm Mikuni VM Carburetor - $143.00 from MikuniOz
You can also get the jetting and needle kit : VM30-83 Mikuni Tuner Kits for 2-Stroke Engines - MZ '84 ETZ 250 for a few dollars more
I wound up buying a twist grip and cable as well.
I don't have pictures, but to mount your mikuni, you will need to reduce the O/D of the MZ manifold slightly (I used fine grit abrasive paper) and increase the I/D of the airbox connection (I used a stanley knife) If your airbox rubber is old and hard, you may have to soften it up in hot water or pay $3 for a new one
good luck
Max
