yea it a street fighter....and i got the bike soon as winter hit and i kept it in the house and worked on in all winter......the other day was the first time i was able to ride it.... i just take it down the road and if it still bogs then i turn around and do another test..... iv had this bike apart alot........
i just took off the fuel filter and pump.. gonna run the fuel line directly to the carbs...... if it fixes the problem then i know i need a new pump or filter... but if it dont fix it then im gonna cry

i just added pics of it..... the pics of it red is it when i picked it up..... and obviously the black is the most current pics of it..... i did add 4 red neon lights for night time town cruising lol.... i wonder if that has anything to do with it... maybe drawing too much power......hmmm

 

was it street fightered when you got it or did you take the upper off ?

and like i said before if the sump of the tank isnt above the carbs it might not work too good , if the sump is above the carbs then gravity will feed the gas to the bowls but if not there needs to be a pump ...

might work if the tanks absolutely full but once the level gets low it probably wont work

 

sorry i accidentally edited my last post instead of starting a new one....... pics added

 

i had same problem to the t.....go to advance auto or whatever parts house you use and get a can of SEA FOAM run a 1/4 of the bottle in the gas tank and and find a strong engine vacum and run a couple caps full through there cut the bike off for ten minutes then dog the living **** out of it for 10 minutes.. i was like wtf ever but i had beat my head on the wall with that bike so much i was just like *** it so i spent 10 bucks on a bottle and done it and my bike ran like a champ

 

dude i have no clue if this would even matter on that bike but have you checked tip sensor?

 

i have sea foam and i put 2 gallons of fuel in the tank and just a quick pour of the sea foam.....i didn't want to over do it..... i'll try putting more in and running it for a bit.....
and the tip sensor has been removed

 

oooo dude i was lookin a buddy postin on f4i but i ran like a half can all together in mine and i only had like half gallon of gas i let it sit 10 min then beat the nuts off of it for ten you know you used enough if it puffs an *** ton of white smoke

 

man deff sounds like its running lean *** hell...and white plugs....that it would only make scene it will run alright with out a big load...1st and 2nd gear and then when it starts to work...lug down a bit theres just not enough gas to keep her spinning and u hear the bog like u ran outta gas sound.....just my 2cents

 

don't waste time with sea foam if are having fuel delivery/dirty carb issues..

If you have a carb problem, you need to pull them apart and at the LEAST just spray them out with carb cleaner


You are saying this is the first time you rode the bike and it runs like crap?? Then the bike probably needs a FULL rebuild on the carbs before it will ever run right.
Fuel with 10% ethanol in it degrades and leaves residue in carbs in under 2 months. You want to always drain the fuel tank and carbs before storage for more then 1.5-2 months.

If you want to just do something quick, just pull the gas tank, pull the carbs from the bike, and just attempt to remove just the float bowls and diaphragm cover, and pull the slide out, and just spray carb cleaner THROUGH the jets, and spray everything out inside the carbs, then let dry and reassemble..

If that doesn't fix it, then you are going to have to do a full carb rebuild. Pulling all the jets out and soaking them in carb cleaner, and using compressed air to blow them out, removing the float needle, and needle jet to inspect and clean, checking the emulsion tubes if your bike has them, and cleaning everything out thoroughly and inspecting for worn parts..

The bike is 13 years old, it's past due for multiple carb rebuilds honestly.. Too many stunters neglect proper maintenance on their bikes. Just have to decide if the bike is a throw away or worth rebuilding

 

 

But really, I wouldn't disconnect the pump, if you ever plan on riding wheelies, your bike would just stall out REAL fast... You would probably have trouble doing balance point wheelies

OMR I think is just saying to try and make sure it's not the pump, try riding it with a full tank of gas and no pump.. . Not a permanent solution unless you never plan on riding on less then a half tank or so, and never doing wheelies...


Really if you want to check the pump, it's as simple as removing the fuel line from the carb, and turning the key on, and seeing if fuel sprays out.. If it doesn't, then run a jumper wire to the fuel pump and see if it turns on...

I'm not 100% sure, but I don't think f3's have tip sensors, that's for fuel injected bikes.. But I may be wrong

I do like sea foam for cleaning out vacume systems, or running some through the fuel tank of a car, or maybe even a fuel injected bike.. Hell I guess it probably wouldn't hurt to run it through a carbed bike every year or two to help keep it running better
But on carbed bikes once they are clogged up enough to run bad, you need to rebuild the carbs..

 

i was asking if he took the upper off and then the bike ran bad or if he got it that way and it ran fine for a while then ran bad because he may have open hoses or an electrical issue if he took the upper off and then it started running bad

 

oh yeah I understand that

I'm just saying his bike can 'physically' run without a fuel pump, but if it came with one, he should definitely run one, except for maybe just a quick test

And I'm drunk right now, and also going through a rebuild on a set of carbs on a fzr600 this week lol

 

im sorry but this post needs this picture

 

You need to dry off as soon as you get out of the water to avoid catching a cold. That's why towelie says, don't forget to bring a towel!

 

out your hand on the back of the pump and fee lif its pumping or not but since your bike is running it is working correctly so its not the fuel pump, if the bike runs good and bogs onely when your riding its most likely 2 much air gets into your engine and starts to bog ( i mad this prob ), to get ride of it i took the plastic attachment piece that fits onto the airbox and goes inbetween your forks, because 2 much air gets forced into the engine and it starts bogging around 3rd and up..... hope this helps bro..

 

ohh and if u need any parts let me know, i still have mine and its getting parted..

 

thanks for the help omr and everyone else......but i dont know if i mentioned that ive had the carbs off and fully cleaned twice.... thats the only reason i dont think its a clogged carb...i'm not sayin its not cuz i may have missed something, but i'm careful and pay attention when im workin in something like that, and iv done it twice on this bike in 2 days... everything in the carbs seem A ok... thats why ive been going through it testing everything i can think of..........
last night the last thing i did was test the fuel pump and filter...i took off the pump and ran wires from the battery to it and it worked fine..so the pump is good.....i bypassed the filter and i still have the same problem... so i'm assuming that they both are good....
one of the previous post about the ram air is an idea, and makes since..... i read that the f3 is tricky with the air box.. you have to make sure all the screws are there and in tight so the airbox can hold pressure... i was missing screws so i thought that was my problem.. i replaced the screws and had no luck...... but the idea of too much air makes since cuz my bike only does it 3rd gear and up......
im getting ready to roll the bike out and cover up the ram air and test it......ill try it completely covered and if that dont work ill make some holes so it can get some air.....

 

ok so i just tried to cover the ram air... i left some space so it could get some air... well soon as i took off, got the rpms up a little and it died.....started back up and did the same thing..........so i uncovered the ram air.......WELL... when i had the bike off with the key on, in first gear, clutch pulled in, i noticed if i roll the bike it will make a hollow plunk sound over and over....if i turn the key off it will stop...it makes the sound about every 1/4 inch the bike is moved.... if the bike moves quicker the sound speeds up....at first i thought it was valves but i know its not that...sounds like its coming from the carbs..... i also thought it sounded like the fuel pump pumping....but the niose is not coming from anywhere near the pump......
oh... after i took the cover off the ram air i took it down the road and it almost topped out 3rd....but it only did it once.... so there is some hope

 

third time i asked this question
