Cbrr 250 WILLNOT run with the choke off
Hi All
I Appreciate any help please
I have a Honda cb250rr 94 model given to me from a friend which was needs a little work which I done ,, fairings and a few other parts .
He had it sitting in garage and not started it for over 1 year
HERE IS THE ISSUE
The bike Will start with choke on only and when I accelerate it will die . Wont allow me to throttle at all, If I pour some petrol done the carbs it will run and let me rev but that’s it until the petrol runs out.
I have also clean the fuel tap and am sure its getting fuel but why is it not running ?
I replace the spark plugs and new fuel and also clean the carbys out, needles and jets., etc . .
So that’s my main problem , Bike will Start and Run On Choke for a few Minutes but when and if I rev it will die
PLEASE HELP !!!!
Thanks so much

What do you mean different source of fuel ? I Drain It and put new fuel , but it still wont go .
Do you want me to try to just put some petrol in another fuel tank of some type and gove that a go ?
Im not sure if i mentioned that If i pour some juice in the carbs she starts and runs very good , i can rev .
But all i got now , it start on choke and if i use accelator it dies
Im thinking it may not be getting enough petrol ?
All help is so much appreciated

Get an empty fuel bottle, kind of like an I.V. drip and replace your tank's fuel flow with a known good one like the fuel bottle. See how long and how good it runs once you do that.
I'm guessing you have some contaminants in your bike's gas tank. Might have to get some muratic acid and clean it out.

I know you cleaned the carbs, but did you adjust them correctly? From the sounds of it, either your not getting fuel to your carbs, as already mentioned, or your pilot jets may not be adjusted correctly. Check to make sure you didn't just tighten them up. Also, double check the floats are not stuck and or are adjusted correctly.
Also, when you cleaned the carbs, how thoroughly did you clean them? there are different idea's of cleaning the carbs, if they werent completely cleaned, that may be your issue.

I do remember i DIDNT touch the Pilot Jets at all , i was to scared noit knowing how to re ajust them
i did follow these great intusctions
https://cbrforum.com/forum/showthrea...retor+cleaning
I am happy to clean it again but what do i do with the pilot jets once u screw them back in ? how do i know the ajustment . i read this in the forum
Pilot screw in/clockwise is less fuel, out/counterclockwise is more fuel.
so is that the tricky part ?
not sure how to ajust
thanks again for help

You really need to get in there, take the jets out and clean them extremely well as well as each hole in the carb with cleaner and air. You mentioned in your first post that if you put fuel into the carb directly it runs better, that usually means fuel is not flowing through the carb well enough for the bike to run, exact same thing was happening to my bike. Also, you said you didnt touch the pilot jets, mine were gunked up pretty bad. What you do is, screw them in all the way until they just seat and while you do that count how many turns it was to get there, write that down. Then remove them, clean them and the holes, and when you re-install them screw them all the way in again and unscrew them the amount you wrote down.
Good Luck,
