Ok so i downloaded the cbr f3 manual. It shows me having vacuum lines that... my bike.... doesnt have on it. i imagine a previous owner deleted them? or i just dont have them... i dont know. I just spent 4 hours cleaning the carbs, put them back on, intake back on, filter, gas tank... etc. I try to start it until i kill my battery, and now i'm frustrated. I think its a vacuum line issue. In the pic below, i dont have what i circled in red. Can someone please post pics of their vacuum lines with their gas tank off???

 

Is this what you're looking for ?

 

thanks idiodirt. im having trouble though because i think someone ripped my bike apart and didnt put things back in that were supposed to belong. like the box on the right side frame rail that youre large vacuum line coming off the intake gos into. i dont have that. and the metal vacuum thing in the center that has one coming into and 2 coming out, i dont have that many ports going into my intake or something. mine is waaaaaaaay messed up. i dont know whether to post what i have and someone tell me where it go's, or i ask someone to post what they have. cause i have no clue.

 

i hooked mine up exactly like yours idiodirt, still no luck getting it to start. i was going to try a spark test with it against the block but my batt died before i could try it. pulled the plugs and they look fine. i just dont understand why it fired up at the guy i bought it from's house... and i get it home 1 day later and i got it to fire up one time, but i had to hold it at half throttle and it died after 5 seconds. that was the last time it ran. completely cleaned the carbs, they are squeaky clean. got the vacuum lines hooked up the way they are supposed to. its closer to being right than it has ever been, but i cant get it to fire. frustrating

 

found out that the plugs were wired up wrong to the coils. 1,4 and 2,3. they were hooked up 1,3 and 2,4. plugged them up right, tried to start it, but it was slow on the cranking, i dont know if it has enough juice to fire it or not. i hooked up a trickle charger to it, will try again in the morning. will it not fire up if the batt is low? not enough amps?

 

just tried to start it after 2 hours of charging... i get half assed attempts of it trying to start... with backfires. will change spark plugs tommorrow and try again.

 

Yes, post up some photos of what you have. If I can't help, I'm sure someone can.

 

got it to run with new plugs. theres a hesitation under 3k. above 3 it sounds beautiful. thinking its still a problem with the vacuum lines.

 

If you bike has a dynojet kit on it then the hoses you have circled in the diagram are not needed per dynojet instructions
