Ok guys your my last resort I have a cbr125r 04 which was great for at least 4 months the last 2 have been hell so from the beginning I wanted to clean my tank stupily washing it with water and dropping some plastic into it I had filled the carb with gunk she wouldn't start and i had blown my fuses from fitting a new light so it all went wrong any how after cleaning the carb 5 times and buying new diaphrams I still has no luck a new spark plug soleniod feul tap and hoses was my next order still no luck so I decided to start again cleaned the carb engine has air fuel and spark and a lovely start roar now I thought brilliant it idles fine aswell I thought ok let's get that battery charged up didnt keep charge so new battery came and it held I was happy anyhow so I goes to pull away bike moves big smiles all around gets about 10 secs goes to open throttle some more and she bogs down pulls in clutch catches her and tried again same problem she won't pull away properly as soon as engine picks up she wants to stop help please I'm gonna try this or garage her it's a last resort help a fellow biker out

 

Hi ,have you looked at the plug to see what colour it now is , did you return the pilot screw to right adjustment when you cleaned the carb

 

I didn't could that affect it also what colour should plug me mate

Sorry matey , when I talk about colour of the plug I mean is it carboned (black) at the electrode or is it white looking, the pilot screw should be 1 3/4 turns out

 

Ok mate I'l check the spark plug and let you know also I thought the idle screw only deals with idling once I rev I don't think the idle screw does anything u ntill I let off the throttle

 

That's correct , but it still takes it up to where other jets cut in , and if the plugs have carbon it shows a rich mixture and once you turn the grip could be flooding the cylinder

 

Take a look at this pic. It amplifies what CaBaRet is saying. I'm pretty simple minded so I need pictures.
