MZ/MuZ Riders

I am looking for a 301 or wilf green 300 barrel and head to convert my ETZ250 to 300cc preferably one just needing a hone and a tart up before fitting. either that or a complete 301 engine if its at the right price! don't mind if it needs a rebuild as long as it isn't shagged altogether. drop me a message if you can help me out with details and asking price.

also if anyone has a electronic ignition set up for the same bike (etz 250) that is working id be interested.
