I have been reading a post about a speedo healer on the MV, and have heard seen a few people have installed the yellow box. I think I would prefer to install a yellow box since it looks like it has the ability to be more precisly tuned. So my question is, is there anyone that has a yellow box installed on a F4 that would want to send me a couple pictures and a quick how to so I can install on my bike? Any help would be great! By the way the f4 has a 3 wire system on it, correct?
