Bike jerking and dying

[managedplum]

Hi everyone! I’m brand new to this website, I’ve been searching up some things on my 2009 fz6r since I got her. I haven’t found too many answers yet on what’s been going on with my bike, but I thought I’d ask to see if anyone here has the mechanical knowledge or different thoughts.

SO. My bike is a rebuild from salvage. I just replaced tires on her. Did a brake fluid change with my mechanic and he looked at everything and said it looked great.

My issue is… it started out jerking in about 4th,5th, and 6th gear. Then just started dying when I’d go into those gears…no good when I’m on the highway. Strugglement with startup after that, but got it going.

I was thinking it was throttle position sensor. So I replaced that. I also just replaced the spark plugs. Took her out and now it’s dying in first gear as I let out the clutch (slowly). My next thought is battery and stator. My budget has been super limited lately so that’s why I’m doing these adjustments myself, but if anyone has any ideas let ya gurl know cause I need my therapy.

Also, no codes or anything popping up on the bike. Idling is at about 1800 rpm.
My killswitch housing is actually cracked, I know I need to replace it. It’s on the list.

Idle should be around 1300rpm, the phillips screw is on the left side of the bike on t he throttle body. You can see it between the fuel tank and frame. Also would make sure the throttle body are installed properly and nothing is loose. if one of the rubber mount is loose or cracked (16 yo bike stuff) it could be why it idle so high, air is bypassing the throttle bodies.

Now your issue can be few things and the only way to find out is go down the list until it's fixed LOL. Not sure if your ride as been modded or have a exhaust or PCV. Now 2009 a lot of things can toward the end of its lifespan. I would do a good visual check then go from sensor to sensor and make sure the fuel pump is still good and the fuel line are not kinked.

I have 63K miles on my 2009 and had to rebuilt the water pump last week... it started pissing on the ground while riding LOL.

I did check the throttle bodies when I replaced the throttle sensor, They look good and secure. Which rubber mount are you referring to? I know I probably need to readjust my throttle opening and closing right (since I replaced the sensor). I only have about 13,000 miles on her and it is a rebuild, but no mods.
Also for putting the tank back on, do you leave both black hoses open?? I know at least one of them is for overfill of fuel but just curious and couldn't find an exact answer on the internet lol

You think this could be more of an electrical issue than mechanical?

Thank you for the response by the way! Good insight!
