Bike idles fine. The issue is when I really get on the throttle. First gear, at all RMP's, seems as though the bike is choking when I really get on it. 2nd gear is fine until 7500 RPM and it reacts the same, choking, lacking power. Often when just cruising in 75-100 mph without moving the throttle, it hiccups. It feels as though many tiny pockets of misfire are taking place. What kind of issue comes to mind? Spark plugs? Air filter? Fuel filter? Fuel injection issues? What are your thoughts? Also the FI light started coming on every day but when I connect it for a error message, nothing is there. The error doesn't seem to get recorded. This is most likely a separate issue.

2 mods

The ONLY mods are 2 bro exhaust and Hotbody undertail. No power commander. The history is hard to say because I am the 3rd owner. The bike didn't do this when I bought it 4 months ago. This started 2 months ago.

Did you change anything in the last 2 months? Or has it stayed the same? The weather change has my bike acting up a little too. If I were you, I'd do a tune up, oil/filter and plugs and get a power commander to get your bike running smoother with the exhaust.

Left Radiator

The only part I have replaced is the left radiator. It had a crack and pretty severe leak, so I replace it with a new one. I think I will start with the plugs and filters. Power commander too pricey for me right now. Could a basic tuneup be a possible fix for this situation?

Start with the basics, plugs, air fillers, fuel filter, oil/filter, to establish a base line of known good consumables. If this doesn't cure it; check the FPR, if it is letting by, the fuel pressure will drop as the demand grows. If the above doesn't cut it, check the charging voltage as a failing generator/regulator can also send things on the fritz. After this you are into testing components and wiring, but hopefully the above will sort it out.

Good luck with it.

thank you all for your input. Some really good suggestions here. I think I will start with the basics as mentioned by most. Wish me luck!

Make sure your battery post connections are corrosion free and tight.
Check your electrical ground connection is also tight and corrosion free, location on the right, just below the upper-right subframe bolt.
The fact that your're getting FI light lit with no fault codes could mean momentary loss of power.
Do you notice if the meter cycles when then is occurs?
