my bike was running just idling. then it stalled and when i went to start it that starter motor relay wasnt clicking, no worries got a new one (not cheep for how big it is $110 anyway). well this happend a week after my mate snaped his neck on my bike so i didnt really worrie to much about fixing it. so the battery went flat, so that was f@#*!d and wouldnt charge up, so we got a new battery now when i hit the started button the relay buzes and doesnt turn over. any ideas?

charge yoour battery up again, they are usually pretty flat when new

if that doesnt work give the relays etc a shake while trying to start it

and chech your connections on the battery terminals, make sure there is good contact

Hows ya mate??

i had the same problem. pull the starter switch of the handlebars pull it apart and clean out. there is a hole on the bottom of it i think where you could blow it out but just pull it apart and clean it out fixwd mine. i thought my starter relay was gone to but it was just the switch. hope this helps

both the formentioned things should be done but if the bike has been standing for a while it may be oxidization between the starter brushes and the comutator in the startermotor, simple way to fix this is to put the bike into gear and rock it back and forth a few times (do this with the ignition turned off you will hear the starter turn over as you rock ) then turn on and try the starter, works on my 450 when it has been parked for a while.

Yeah we go it started to day, we charge the battery up and that didnt do anything. so we role started it. but wont start under its own power. we thing the battery is to small. not enoughf amps.

My mate hit a wash out at about 90+ kmh and went up a bonk and hit a tree. he was been cocky!!! it was only like the 3ed time he has ever riden. but he broke C5 in his neck (the same one superman broke.) also broke his wrist. he had a neck brace on for 8 weeks or so. he it all good now but he has changed in the head he just not the sane bloke anymore.

Does it start with a bigger battery, (like a car battery)?

i dont think the bike could charge a car battery. if so i could fit a small oddsey in there.

'Jumper leads' & a car battery????If it will start then orig batt has a prob.If not then there is another fault.

not important about charging, just to see if it will crank it over. if it will start then you can check your charging system to see if you're getting enough to charge the std batt.

worn starter brushes or poor contact= higher current draw while cranking most starters draw between 35-70 amps when cranking if you only have a small reserve ie 14-18amp hours it may not be sufficient to start your eng, if a jumper battery works then it is because either your battery has insufficient charge or your startermotor has to much current draw and you may need to have the starter rebuilt, if the solenoid clicks when attempting to start then it is most likely the battery or connections if nothing happens when you hit the switch it is either the switch or the startermotor to find out which it is bridge the two large connctors on the solenoid usually 10mm nuts with a large screwdriver ( the blue handled stanley is ideal for this because it can handle the current load) if the engine does not crank then it is the startermotor or connections if it cranks over it is the switch or connections, this test can be done with the ignition switched off, and/or with a jumper battery connected

its pulling 5.5V under load. where pritty serted that its the battery. not enough AMPs to crank it over.

Grub,the amps is the draw on the reserve charge not the amount of current in the battery, amphours is the amount of time it will take to discharge the current at a specific load ie. 14 amp/hr will take 14 hours to discharge @ 1 amp, the larger the battery the higher it`s amp/hr rating will be, because it can physically hold more current, if it draws 5.5amps when your charging it this has no bearing on its ability to supply current when it is drawn upon, all batteries will show a high current draw on a battery charger if the battery has low voltage stored in it.
If on the other hand you used an amp meter in line on the starter high voltage lead to get your 5.5v load reading the there is definately something wrong with the circuit within the startermotor, because when cranking it should draw at least 30 amps ( that`s why you need such a heavy cable between the battery and the starter motor ) I you don`t have an ammeter to measure this take it to an autoelectrian, to get it tested,they should also be able to tell you excactly where your problem is.
