Ok so i spent a good amount of time searching and couldnt find a case like mine. I bought my f3 and it ran ok had a rough idle so i figured id add some fuel injector cleaner to the full tank of gas after about 3 weeks of riding it. it rode fine until the next day when i went to start it and it turned over idled a little and died, then just cranked turning over once or twice and cranked till it was just cranking and not turning over at all. i checked the gas, had about 35% left so i figured the cleaner might have settled at the bottom of the tank causing a bad mixture. so i lef tthe bike came back in the morning and filled the whole tank and after cranking a little it started up and ran fine. this happened again 2 days later once again filled the gas back up cranked a little and started, this time wasnt as fast as the last though. i figured its because of the mixture still being messed up and i need to keep the tank full till it goes through the whole system and is diluted enough (even though i added not even half of the bottle of the cleaner) Anyway last night i left work and rode over to the gas station just to top off the tank again, filled it up all the way and rode off to the highway. got on the highway got up to about 75mph and didnt even make it one exit till it started acting like its running out of gas. so i pulled over and it completely stalled, cranked but refused to turn over. got towed tried it this morning still the same thing absolutely refuses to catch, choke or throttle do nothing. what could this be? i added so much fuel since the cleaner that i figure it would be through the system by now. are my carbs clogged? sparks messed up? it seems like its not getting any fuel at all with a full tank. any suggestions before i rip it apart would be great.

heres a pic of the bike since im a new member and i love showing my baby off

 

Man, those colors look sexy.
Carbs could be dirty and clogged. When I bought my bike it started great, ran great but after 5k rpm it would run like a costipated man trying to run a mile. Clean the carbs, changed my plugs and vroom ran like new

 

thanks for the advice man, im kind of new to bike wrenching is there a particular spark plug i need to get, do the have it available at autozone, if so how much do they usually run for. im a pretty broke college kid and this is my only way of transportation besides my longboard so all the fixing has to be done by me and done reasonably well or im screwed

the colors are super sexy though specially the candy red real nice in the light

 

fuel injector cleaner?
for a non fuel injected bike?


seafoam. use seafoam.

 

NGK brand, advance auto/autozone should have them. If you don't have an owners manual you can download one, its good to have

 

im a college kid too so i get where ur coming from, i do all of my own work.

spark plugs are cheap. 4 of them will run you about 12 bucks and u can get them at Autozone. i dont know if there is a particular type but u can ask someone there. dont forget to gap your plugs to spec before you put them in.

one thing not mentioned above is the gas tank itself. im kind of having similar issues with mine. from what i understand it could be 1 of 2 things. either the vent inside the tank is clogged and creating a vacuum in the tank and not allowing gas to flow or it could be the contacts in your fuel pump. these burn out (pretty rarely) and need to be replaced. the contacts are going to set you back about 40 bucks. i'de start with the cheapest and easiest fixes first. check the vent, get new plugs, clean the carbs (can be somewhat difficult if you dont know what your doing), then replace the contacts.

here's a thread on how to replace ur contacts

im not gonna say that one of these things will fix it but its a good start

 

i agree wit the seafoam. it'll run you about 9 bucks at Autozone and it'll do wonders for ur carbs

 

I will say the NGK's are nice.
but get the iridiums.
CR9EHIX-9 is the number.
i've only found em on ebay. they will run you about 30 bucks shipped, and they burn hotter. my bike woke up from them.

 

thanks for all the advice guys! i will start this weekend and see what happens.

 

Each time it wouldn't start and you add gas to start it. Was the gas in the tank that you could see at the same level?

What year is it and how many miles?
