While it's probably not as good as having a dedicated 12mm O2 sensor bung, there are an awful lot of people doing it that way. I haven't read any doom & gloom posts on forums about it...

So I'm pretty confident it will be OK....

 

Pull then reinsert the main fuse.

 

that makes me feel better, its onlly a 1/4 inch, how bad could it be??? haha

 

I've disconnected the battery many times, 10 mins at a time and the issue was the same. I think that has the same effect as pulling the main fuse right?
Also ordered a Walker O2 sensor, installed it, and no more check engine light. No more batter light.

I'm pretty confident the issue was the Thundermax ECU, since all the problems went away with the stock ecu. Bike sounds a little different with the stock ecu. A little less loud.
