ok ihave a 09 xb12r and a couple days ago i started having running issues when at idle it will randomly die, i have a miss at random times, and when getting on the throttle hard the bike will bog way down before taking off. no check engine light and i have done several tps resets as well as reset the ecu. What do you guys think?
fuel pump going?

i think my $400 tune file might have gotten corrupt some how... cause i just decided to revert back to my last tune to see what would happen and in the short ride i took it rode great just slightly less power than what im used too now. oh i forgot to mention that it started a couple weeks ago after the bike had been left out in the rain dont know if that has anything to do with it or not

highly unlikely it's your pump. you can tell a pump on the way out as cold start after sitting over nite or longer takes unusually longer cranking time to actually start. and gently rolling back on the throttle as in coming out of a turn and accelerating, or accelerating after shifting from 4th to 5th gear gives you a pronounced and noticeable bog or hesitation.
Fuell pump for a mustang at autozone is though! And im going to try and reload the tune in the morn ill let you guys know how it goes I really need to replace the fuel pressure reg with a higher flow unit and have it retuned anyhow cause my injectors are maxed out at 5500rpms and im making 96hp there so I still have 1700rpms to work with and once I can give it more fuel I should be able to easily break 100hp which is my goal
