This is the prototype Oz-Flow BBTB, it is 60mm. There is one thing wrong with it and that is the idle adjustment bracket cracked. You can either get it welded and retapped or you can put a nut on either side and screw through both (holding it in place). Another option is to adjust your throttle cables so the idle screw is not needed. This uses your stock pulley and springs, you will need to get a new nut for the pulley though since it is threaded different than stock. I am getting rid of this because I want one that will allow for cruise. Asking $175 OBO shipped, pictures to come soon.

 

BTT...
