I did a koko reset on the ecm. No other changes. Now it runs rough, pedal is touchy. If I push through it to 1500 rpm is runs fine from there up to 3000 rpms. Anyone else experience this kind of thing? Does a koko clearing also require a reflash? This just is not making any sense. I'm at the point of selling this thing. Parts are not only hard to find, but expensive to purchase, even used.
