pls help!

heya guys

recently put my bike back together heres the thing...... actually 3 things.

ok so the bike was sitting for like 6 months so it had an understandably flat battery recharged it and rode it yesterday for a bit, made a few stops, visited some mates all seemed well with the bike appart from the front wheel allignment.

come today go to start the bike and it kinda just dies like i have a very flat battery and then wont start + headlight not on....

i jump start it and it runs ok turn off the bike after about 30 mins of riding and go to turn it back on after like 5 mins completely dead, dash light just so barely on, do bikes have alternators cause if they do then i think mines been royally shafted, the only thing is that yesterday it ran and started fine every time n today its all messed up.....???

next problem, the indicators towards the end of my ride today where playing up badly they seem to come on sometimes and not others with no change to anything on the bike at all they also occasionally go nuts like light up at twice the normal speed, they seem very tempermental..???

next one.... find that when i fully open the throttle in 2nd or 1st gear, high in the rev range like above 11,000 its seems to lose power pretty dramatically for a bit then kinda keeps goin till i shift, it keeps reving but just loses power..... seems like maybe a fuel problem???

hey thanks guys any help would be awsome!

Whats up pistolpete. Hey what kind of bike do you have again?

It definately sounds like a problem with your charging system. The way you described it I'm thinking it could be 3 possible things. Now first off thou, double check your connections to your battery to be sure they are on snug. Ok.

Either you have a faulty battery, a bad rectifier (or the wire harness), or your stator (which is basically your alternator). You'll need a multimeter for this. Damn I hate dealing with the charging system!!

I don't have any time to post anything else up, but i'll respond later and try to help you out. See ya

take the batery to a part shop like O'reilys if you have one they cheak them for free if its good do the same with the stator

cool thanks guys, ill have a look at it when i get some time. im thinking the indicators just some dodgy connections somewhere.... and maybe the strange power loss is just a spark problem since sometimes it happens and not others.

ill just have to have a good look at it sometime

by the way the bikes a 98, kawasaki GPX 250

sounds like exactally what my bike is doing

its either the Stator(altenator) or the rectifier (like kurt said)

i am positive that its my stator because i replaced the battery and the fucking thing just died about 30 minutes later...

when i got to higher RPM's it the tach would bounce and stuff... not enough juice to give everything what it needs.... the blinkers would work when they felt like it...

haha now the good news... ;) Stators are either about 350$ OEM... or as i have found electrix sells mine for about 120 w/ shipping from UK.... Tough decision

if you cant find it.. just email them and they are very knowledgeable... they told me i need to make sure which one i need... so i have to take it apart and measure it..

anyway hope you have good luck

on a side note for the indicators if ones not hooked up itll make that side blink faster currently i only have my back ones hooked up due the the fact i havent got a replacement front yet and it makes them blink insanely fast

Alright Pistolpete lets see if we can figure this out.

Ok so I reread your original post and it does sounds like its either the rectifier or the wire harness to the rectifier. First thing I would do is check the voltage of the harness that connects into the rectifier. Find your rectifier and disconnect the harness from it. Get a multimeter and switch it over to volts within the 12volt range of your battery (to avoid decimals or bad readings). There should be a red/white line and a green line that runs into the harness. Those are the lines you will want to measure. The + on the red/white and - on the ground. Now when you measure the voltage, it should read the same as the battery. If it doesn't then the harness itself is bad.

Now as far as checking the rectifier, you'll have to measure the resistance between the prongs that connect to the wireharness. Since I don't know what the exact specs are for your bike, it would be hard for me to tell you what to look for. For my CBR the 3 prongs for the stator (yellow) should read between 30-500. Yellow to ground (green) should read 10-200. And red/white to yellow and then to green should read the lowest (up to 10 to the yellow and up to 20 for green). If the resistance between these aren't normal, then the rectifier needs replaced. Of coarse you could always go to a motorcycle shop and have them test it, but I don't know what they would charge you.

Anyways thats what I'm putting my money on. But the charging system is a pain in the ass. Let me know what you find out. Later

hey thanks for the help guys!
clubster.....sounds like we r in the same boat then

thanks heeps kurt ill give that a shot when i get the time, thanks guys!

Sorry for replying so long after your posting:)Hopefully you got it sorted out?
One thing worth checking is the carbs,if the bike has been sitting for 6 months they could be gummed up.
