CBR 400 NC29 loosing power

[brooklyn]

Iv had my bike on the road now for just over a week, all seems well but every so often it runs rubbish as in it wont pull when the throttle is open.

I can go down the road and it runs fine then all of a sudden when i change gear or let the revs off for a bend and open it up again the power is not there. Its like the fuel is running out then after about 100yrds it will be fine again.

Iv changed the plugs, blown the air filter out with a compressor..

I was told it may be the air flow meter if its even got one??

Any ideas

Not too sure, but you might be right about the fuel, could be a trapped fuel line.

Get a Haynes manual and service her, you may find something to do with carbs or w/e.

Worth a try, no? Once you've ruled out what the manual covers the problem should be easier to find..?

I have managed to download the manual so il have a good look through it

Cheers any way

Could be poor spark. Carbs might want balancing and the mixture adjusting
