Hi, my gsxrr 250cc is dying and wont take any gaz when runing at low rpm, i will be at full throtle and the engine is barely running. After half a minute the engine rpm gets high again and if i do give it a lot of gas, it will eventually run. When runing at high rpm, i do not have this problem. Only at low rpms, it seems to die... What do u think?OHHH and i as soon as i start the bike the moring with the engine still cold, i do not have this problem. Just after few minutes it starts doing these dying stuff...So if i directly run the bike after start up, it goes up a hill, and run smoothly at low rpm. Could be elctrical?? mechanic is telling me my carbs are fine.

It could be ignition related.

However, Id suggest looking at your plugs, see what colour they are. Often If it runs when its cold but runs badly when warm it means that the mixture is too rich.

If the plugs are sooty and black its rich. Then you need to start checking your pilot screws and float heights are set correctly. Also check the choke mechanism isnt seized and staying on when the lever is returned to normal.

Other thing to check is your airfilter, if its clogged itll run rich.

Another think, when runing at neutral the engine doesnt die at low rpm...its only when i applly a load at first gear and want to run the bike up a hill...it dies if i dont give it suddenly too much gas. Thx guys

sounds like a mixture problem, too much of something(maybe oil) that chokes the bike up. or (i had a similar prob on my bike) it sounds like your riding the bike hard, it may be getting really hot and oil may not be getting into the barrel causing your bike to nip up abit.
just check your oil pump is set up alright, and also make sure your bikes getting enough air.
oh, i am assuming that its a 2 stoke, if not,sorry Smile

but it should be similar. hope i've been some help dude.
i'm just sharing what i know.
