SOURCE: 85 suzuki 125 4 wheeler that is out of time how do i time it

With your piston @ TDC (top dead centre)(check the timing marks) all of your cam lobes should be pointing as far away from the valves (or rockers) as possible. Alternatively, the cam lobes can all be very close to opening the valves. This is called "rocking." Once you have set it up like this, you should turn the crank in the direction of rotation to check that none of the valves touch the piston. Keep turning the crank to check the valve are opening and closing at the right times, ie "****, squeeze, bang, blow"

SOURCE: YZ 125 Keeps burnig piston & Ring on Exhaust

only reason would be your running too lean. which causes more heat, which causes pre-gnition and pinging. Also if timing is off you create more pressure which in turn causes more heat

SOURCE: how do i go about replacing the piston and rings

Take off seat, and tank.
Drain coolant, remove exhaust, remove coil, and ground wire from head.
Remove triangle head stays, and spark plug.
Remove right side power valve cover, and clip and spacer for the power valve arm.
Remove four cylinder nuts.
(If you remove the lower radiator hose that goes between the left and right radiator, you can get the cylinder off without removing the head.)
Use a soft blow, or dead blow hammer to free up the cylinder (Piece of wood)
Use kick starter to get piston low, and carefully remove cylinder upward.
Put a rag around connecting rod, and remove piston pin clip on one side. (So the clip doesn't fall into engine) Then push the pin out and remove the piston.
Note, you will have a mark on the left side of the cylinder of "A" or "B" for a stock piston, but Wiseco's don't use this.
Use caution when putting on the new ring, and getting the cylinder onto it as not to twist the cylinder because it will "catch" the end of the ring and do damage.

SOURCE: How do I get to the piston rings on a 1981 honda xl 500 off

the cylinder will slide off the top of the piston, then you can replace the rings and slide the cylinder back down over the top of the piston. The bottom edge of the cylinder sleeve should have a small chamfer in it to aid in getting the rings into the cylinder.

Honda wave 125 producing white smoke

First clean your air filter element, a clog air filter means air will be forcebly sucked from your engine together with engine oil producing white smoke. Or it can be worse, a broken piston ring, you need to change a set of piston ring. do not run your engine if it has a broken piston ring cause it will damage your cylinder block and will cause engine seizure.

85 Honda trx 125 ran great when parked, kids tried to start and no luck. Checked spark, seems really weak, getting fuel. Any suggestions?

Start with a fresh spark plug. Part of the spark may be traveling to ground via the carbon deposit on the ceramic electrode insulator. Drain the carb; condensation in the gas tank may have built up in the carb float bowl. Engines don't run well with water as fuel. While servicing the bike, clean the air filter and lube the cables.

Why is my motor oil coming out my tail pipe?

Bad Piston,Bad rings,bad valve seals,Cracked cylinder head.cracked block. Don't forget now there is a lot of suction and compression going on in a motor. If any of the above are happening in an engine the suction will pass oil through a bad piston or rings or any of the above and cause Blue smoke and spit oil out the exaust along with blue smoke.

Sounds like carbon fouling from excessive oil being burnt. Is the exhaust a bit smokey? If so, a new piston and rings et may well be required.
