Ok first of all its a 94 F2, 20,000 miles very well maintained in nice shape.

V&H Pipe and a Jet kit.

When starting it I run full choke it starts imediatly (1-2 rotations) idels ok and slowly climes in idle as it warms, before it is even above the C maybe 5-6 minuts of idel it slows down and dies. If I were to try to start it aging (which I have) I can crank for a million years with every different variable and it would never start. Letting it sit for 10 minutes or so sometimes helps a little. HOWEVER if I try a roll start it will blubber a couple of times not start but after one attempt at a roll start it starts perfectly every time after (starter not roll) with or without choke.

I dont get it, I know CBR's are a biatch cold thats why they went injected but still any reason for this???

Thanks in advance,
Morgan...

Not sure if this would even help, but you might look to see if your fuel line is pinched. I had this problem and the bike wouldnt start at all, but then i could shake the bike real hard or move it and it would start. I got to looking and the fuel filter was empty, I moved the line and it filled right up and cranked. 2 zip ties and not another problem starting. I usually start mine full choke, and it cranks right up, then go no choke right away and keep the engine running with a little throttle until it warms up enough to idle (which usually takes about 30 seconds of manual throttling before it will idle with no choke.

 

i start it with full choke and as the idle climbs i slowly walk the choke off untill it is fully closed.but definately check your fuel lines (the overflow ) there are 2 of them, i had the same problem also and i pulled the lines straight and the tank un-vapor locked itself... hope it helps.


why are you idleing it for 5 minutes??? thats a LONG time to just sit there... IMO

 

No line comming off the back of the tank, my printing company happens to share a parking lot with the local Honda Dealer and I talked to one of my dads friends over there and he said its probably a carb issue, if it was vapor locking it would be more prone to do that when hot also and its prefect once its warm. They give me a discounted labor rate so Ill probably just drop it off and have them go through it.

Thanks for the help.
