Bad Idle

I have the 1991 cbr 1000f. I rode the bike and the motor ran fine. Two weeks later I started it. With full choke the motor will run, but the motor will not reach full rpms (around 4,000 with choke) when it has warmed up. When I turn the choke off, the motor dies within seconds. I coaxed it onto the road, and with choke off, I ran it wide open throttle and it runs just as strong and fine as usual. Is this a carb problem? Should I take the carb off and clean it?

Sounds like a carb problem to me , but I'm no expert!

Luckily for you there are a few experts on this forum

They'll let you know what to do

Maybe run some carb cleaner through it....like seafoam in a tank.
Sounds like a pilot may be a little dirty or something.

As above ...plus -
...run the std issue vacuum issue test ... run her with the tank cap cracked open to allow her to vent ...
If she runs fine like that ...check all the lines from the tank and the Carby's lines ..for kinks ect ...

Then get back to us ...
