Mystery solved.

All this tuner does is add fuel. I’ve taken off innumerable amounts of these over the years. The complaint always starts with “my bike runs poorly and gets terrible fuel mileage!”
This is a great addition if you determine your bike is running horribly lean.
This is a terrible addition if your bike runs at an acceptable AFR without it.

Oh, definitely, that’s understood. The bike has the signs of Stage 1 being done to it with the vented airbox and exhaust. That being said, I just got the bike as a project and was curious. I hadn’t checked the afr yet. Tires were so cracked I haven’t ridden it. The aforementioned stator issue had killed the battery. With jumper cables the PO was able to get it started, but it did idle ok, and rev up ok. A little black smoke when you rev’d it up a bit, but it came from a town at 7,000 ft elev, the battery was crap, and the fuel was a few months old. I was just happy the fuel pump ran smoothly..lol.
In the next few weeks I plan on changing fluids, battery, and fixing the pin on the regulator harness or replace with OEM. I’ll establish a baseline and go from there.
