Hey Guys, first post apologies for any newb things! So I'm trying to troubleshoot the ignition on my 2011 Hyosung GT650r EFI. Yes I know many of you don't like the brand, I'm OK with this, so any suggestions of "you shouldn't have bought it", "just ditch it", "Hyos are crap", any of that will just be straight up ignored as I do not want the thread to turn into another brand bashing exercise. I'm an engineering student, I like fixing things and that's just what I'll do, all machines are just that... machines. Unfortunately I lack the experience, detailed knowledge of all vehicle systems, and some tools to fix all things by myself, so that's where I'm hoping you guys can help me out Here's what I'm facing. The front cylinder does no longer fire. Through extensive testing and advise from several mechanics (swapping ignition coils, new spark plugs, swapping plug caps) I determined that the failed part was the front ignition coil. I've replaced the part twice in quick succession now. The first time I thought I'd received a faulty replacement coil as it burnt out again on the first ride, but the second time I began to think there is a little more going on here than I had thought. Clearly there is something that is forcing the the ignition coil to fail. I've explained this to a few friends that are mechanics and have received little in the way of what could be causing it on an EFI engine. When it failed: So on my maiden ride after replacing the coil for the second time I noticed the bike starting to miss as I got into the higher revs (>6000 rpm). As it was a long ride home I tried to pace myself as I feared getting stuck somewhere on the road. It started to get progressively worse as I rode, more and more misses, with some missing periods lasting a few seconds when I held throttle at a particular point. Once I got on the freeway I slowly accelerated up to speed. I got to the bottom of a big hill and as soon as I started climbing (which I'm associating with extra load on the engine) the front coil cut out completely and I was back to running on the single cylinder. Some things I've tried: Checked wiring harness to ECU and to battery. When ignition is set to ON, voltage at both coils is 11.22. A little under the 12 volt but I think that's ok when the bike is not running. The next thing I'm considering doing is replacing the ECU, but that's around $300 so I'd rather not replace any more parts until I've identified what exactly is wrong. Any thoughts or suggestions would be greatly appreciated! Thanks.
