Help! Stuttering/ Won't Accelerate

Hey Guys,

First time posting here. My name is Dan and i'm riding a 2004 bonneville. I'll have to post pictures soon.

Bur i have an issue. My bike died as i was pulling into a gas station. My gas light doesn't work and i was definitely low, so i believe i ran out. Anyway, i filled up and it started right up, but now it stutters/ misfires at about a quarter throttle, regardless of gear, and will not accelerate if i pull the throttle past this point.

Any ideas on what it could be? My initial thought was a blocked jet, so i got some fuel treatment that i'm throwing in tonight.

 

Thanks for the quick replies. I'll try draining the float bowls and see if this fuel system cleaner can clear the jets up. I'll report back with results. Until then, here's a pic of the ride! Have some new Gasser Customs black ceramic slip-ons getting here on monday too!

 

Yeah i'm wondering how that's going to go. I believe the current slip-ons are Dunstalls (last owner installed), which are pretty loud and what i would describe as "Brappy". Love the sound but not so much the size or style. I'll definitely post pictures after the install and whether it sounds like a machine gun on decel or not.

 

It’s funny you should post this. I recently went to replace my air filter for the first time and upgrade to a K&N. After watching a video on it, I was really confused when I didn’t see a snorkel! Seems the previous owner had the insight to get something similar to this.


And thank you all for the warm welcome!

 

I was finally able to dig in to the bike. Took the carbs out and there was a ton of sediment, and even a tiny leaf in the float bowls. One main jet had something in it too. Cleaned them, threw them in and it fixed the main issue.

Also installed the gasser customs slip ons. I'll include a picture. They sound wicked, but as expected, i'm getting some backfiring. It isnt too bad, but i also noticed my throttle response below 25% throttle is a little sluggish now. I didn't clean the pilot jets aside from spraying carb cleaner through them. I'm wondering if they need to go up in size or if maybe i need to just play with my throttle rigging. Anyway, heres an updated pic! Next up is to black out the badges and headlight dome, then try to bob the front fender.
