I read an old post (forget who the user was), he had the EJK controller installed at no cost. He said he was the first cbr300 owner to ever have it done. He was super impressed with it. I've been researching their product and comparing to other products it looks great. Very simple install too, just piggybacking the fuel injector basically. You can uninstall the O2 sensor if you want. Maybe in the future for that. I'll see how it runs with just the fuel controller first.
