CBR F4i HELP!
Yesterday I was out for a ride and the bike started hopping and bucking on me. almost felt like it was running out of fuel but I just filled up. I stopped at a local motorcycle shop and I shut the bike off and then I could not get it started. I jumped it with another bike and it fired right up and ran fine. Is this just a bad battery? I know if the battery has bad cells then over time, it could cause the bike to not run right... No lights have ever came on the dash and it ran great after the bike was jumped and went all the way home. I put the battery on a tender and the battery is fully charged so according to the tender, the battery is ok. I am hoping its nothing too serious seeing that I just bought the bike. Any information would be great! thanks

All signs point to battery/stator issue imo

Yes, likely a battery. The regulator/rectifier is a failure point on the F4 series (both carb'd F4 and injected F4i). Maybe on the F3 and/or earlier as well; IDK. Check cbrforum.com as well if this doesn't fix the issue.

Re: CBR F4i HELP!
Sorry for the double. Here's what that should have said:
There may be a battery problem, but the regulator/rectifier is a failure point on these bikes. Check both. (now read the rest of the post above)

Re: CBR F4i HELP!
Charging systems are a pain....
verify battery is good and proper out put 13.6 ish to 14.4 ish volts
find out what internal resistance to rectifier is and measure with multimeter
find out what output the stator should put out and measure on bike with multimeter
I doubt this is a fi issue but if not in the charging system i would assume fuel pump
