Hi all, have just aquired a zxr400 l3 , broought it private , it will not start off the button , will just keep winding over til it flattens the battery, it will however splutter from time to time, altho if i bump start it, it fires up and runs sweet ...... could anybody point me in the direction i need to be investigating, to save me countless hours of searching ?

cheers

Strange one. How old is the battery?

Hi RedexRobB , in all honesty i have no idea, but the guy i got it from says it was put on last summer .

Could be saying that to get it sold.

Its strange in that it will run on a bump start but not off the button, which is why i asked how old the battery is. Have you been and taken it for a run since you had it? How does it start then?

Sounds like battery takes a 12v charge but doesn't hold the amperage so the bump start gives it the kick it needs.

New battery time. Left in the bike over winter months can and does kill batteries if they are not used.

MM!

PS. I got a spanking battery that has the same problem - good for running an inspection lamp and thats about it !

Thank you both guys for the reply's, i havnt took it out for a run yet, worried in case it wont start, heard alot about zxr's not starting when hot ... not that it that hot lol , will invest in a new battery and see what happens, watch this space

mine did a similar thing after i overloaded the gennie with more powerful lamps and heated grips. All it was was a slightly flat battery. I'm not kidding, these like to be at 90%+ charge to start, whilst my old gpz will start after 4 weeks under the snow!
just give the battery a day or two on a good maintenance charger, and i bet it'll fire.

Hi gavinfdavies, have the battery on charge now , have ordered a new on anyways, got new sparkplugs coming too , so fingers crossed it will all be good, i have a gsxr 08 plate , but for some reason i just cant wait for the summer to get out on this little zxr and a bonus to boot , after reading some threads on here i have since noticed i have a "M" CDi box fitted

i'v found that the hot start was more a thing of not letting it idle when iv stopped so like pulling up at a petrol station and instantly turning it off or out of balance carbs were my biggy them f******s go out alot

bad and good news guys ....... i put the battery on charge , wasnt having any of it ..... battrey is knackered, i had ordered a new battery tho , charged this , put it on , a very small bit of choke , quick stab at the starter button and away she went . Just a few more things to sort out and she will be good as new .

Thanks all
