Question about 2002 kawasaki KMX 125

Kmx 125 engine knocking

Hi, i ran out of oil the other day(2 stroke) the bike died, filled it up after walking it 10 miles home, it started but would die down and not tick over just cut out, thought it would be the rings so i bought a new set and piston but it still does the same but with a knocking noise and seems to have little compression there. also i had it re-sleeved 9 months ago and there is no damage to the bore.
can any one help?
Thanks

    Hi, thanks for advice. I have checked piston to cylinder clearance and all appears fine as the new piston is 0.5mm oversized its a better fit than one I took out as that was standard with oversized rings. The rod has no up/down movement and shining a torch down into bottom end there are no signs that those bearings have gone and nothing in there that shouldn't be. Obviously I would have to crack it open to check other bearings but surly it wouldn't start if they have failed. So I put it all back together and started it again and the knocking is still there and still not tick over, the only way to describe it would be, it sounds like some thing is rattling about in the cylinder (piston but i cant see that myself) as its brand spanking new. small end bearings look ok and in tack. So I dont know and am short of money so cant take to garage. Anymore Ideas?

    Cheers

    rebored because cylinder was in a bad way, with deep scores and a chunk out of it, been fine since it was done then with running out of oil, the knocking started and with new rings and piston its exactly the same, on inspection i see no damage and a friend says theres none(more experienced than me) but hes stumped too. Piston pin bearing looks ok and all there with normal movement. Is it possible that its worn out and rattling about, but dont get the compression loss! the noise is definitely coming from top end somewhere. I know that lack of lubbrication is BAD, what sort of damage is it likely to cause?

    Hope this helps to help me. Thanks again or your time on this matter.

    sorry you did say could have ruined any bearings. any idea of which ones and how could i tell without cracking it open as i will have to get gasket set and seals just to look. I will prob have to crack open anyway so spose i'll have no choice.

    Thanks again

  • mrchlorine Jan 30, 2009

    Hi thanks again, will get on and do that tomorrow as have had other things on today. Will let you know how I get on.

    Hi, had a lot of snow lately so not been able to work on bike.

    I bought a new cylinder and piston as was cheaper than re-bore and its running absolutly perfect now. Cheers

  • dstar2kuk Apr 10, 2009

    I had the same issue, the oil ran low but didn't run out, the top end started to make a ringing knocking sound and there was increased vibrations felt through the footpegs, I went to the garage 3 times and was told it was just a top end rattle and nothing to worry about, after 2 days of comuting to work with the noise getting worse the engine on low revs started to give a scraping sound, there was no loss of compression and on high revs the bike moved.... I went back to the garage and was told again its just top end rattle! Can anyone shed any light on top end rattle as it felt like the enging was seazing!

Check the piston to cylinder clearance.You very well could have wore either the piston and/or the cylinder.
Also check the rod for up/down play.Running out of oil could have ruined any bearing in the motor.

    Did you rebore with the oversize piston?How is the piston pin bearing?

  • Brad Hurt
    Brad Hurt Jan 30, 2009

    Before splitting the cases recheck the piston to cylinder clearance with a gauge and take the piston pin and bearing out and mic the pin and check the roller bearings out close.
    That and the rod bearing are most likely to be worn.

1988 KMX 125 leaking oil


Hi, 01495718350 external oil deposits fall into 3 categories:
1. WEEPAGE is oil that is sweated pass gaskets, seals, o-rings, and crankcase seams, it's covered by dry dust and is normal for older engines with lots of miles, no repair is necessary.
2. SEEPAGE is the same as weepage except the deposit is wet and confines itself to a specific area, repair is optional depending on the owner's cleanliness criteria, the deposit location and the weight of his bag of "DRACHMA"
3. LEAKAGE is the same as seepage except it is enough to drop to the ground leaving a spot. Repair as necessary.
To find the source of your oil leak, start at the point where you see oil and trace its path going up and forward, blowing baby powder from the palm of your hand will help in those difficult to see areas if there is too much oil present then buy a spray can of engine degreaser apply it to the affected area then rinse off with a pressure wand or garden hose, use compressed air to blow off excess water or just let it drip dry, take your bike for a 15 minute ride and check for the leak.

2002 Kawasaki KMX 125 backfires


Hi, Darrel and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Faulty main circuit breaker and or connections.
4. Faulty ignition coil and or connections.
5. Faulty spark plug, oil or gas fouled, wrong heat range or service type, wrong gap, loose in the cylinder head, broken electrode or insulator.
6. Faulty spark plug cables, leaking or broken, internal damage check for spark leakage in the dark.
7. Faulty ignition module, switch, CKP, MAP, CMP, sensor and or any connector in the ignition circuit could have corroded, loose, or broken pins/sockets
8. Burnt exhaust valve or air leak in the exhaust system.
9. Improper valve clearance (too tight).

Hi, Dingbat_t the answer to this question is way above my pay grade for this situation I would call my local dealer or reputable shop's service/parts department and inquire about any possible quick fix, answers, or parts inquiry. If necessary, transport your bike to the dealer or shop and have a professional technician take it for a test drive, if it is in running condition, and give you a written estimate of repairs and answer any specific questions you may have about your problem.
