Question about 2003 ATK 125 4-stroke

Piston rings positions

I know where the oil ring goes. The other two rings go in which order? - They both look the same size, although one has a shiny edge.

Hi johanjur
It is important that the rings all go in the right way up and in the correct order. The ring with the shiny edge may be tapered, the shiny edge then should be closest to the top. Check the rings themselves. There are often markings on them, and they generally face upwards. Hpethis helps you. Cheers

Plugs fouled

there are two ways plugs foul up is too much fuel or oil is getting in to the cylinders,does the bike blow excesive amont of smoke on start up and when you are riding,and is it one spark plug or all if it is a single plug and comes out black with oil then it could be a vave seal or it could be a damaged oil ring on your piston ,if it is doing it on all cylinders then more than likely the piston and rings need replacing and the bores to be honed or rebored to the next size piston and rings,hope tis helps cheers pete

Im putting my 05 yz 125 top end back together my question was what is the torque specs on the head and on the jug

G'day. The torque specs for the 8mm head bolts is 18ft/lbs.the jug?(cylinder or barrell) is just tightened down even & firm, as there is no acess for a torque wrench.
OK. other things to note.
Clean the cylinder first in solvent(kero or fuel).Then in warm soapy water in a bucket. Dry-(compressed air is best for this-wear eye protection).once dry lubricate all power valves with oil.
Using a clean white rag-soak the end in your 2 stroke oil & wipe the inside of the cylinder surface untill the rag comes back clean(you will need to do it a couple of times-turn the rag over & do it again).Lube the new piston just before assembly-Also pour a little oil down the main bearing oil holes & over the big end too.
Other things to be sure of are-
Piston on the right way round-arrow to the exhaust.
Rings right way up. Some 2stroke dirtbike rings will only go one way up.Look CLOSELY at the ring ends-on the upper or lower surface there may be an etched dot or "T" or "N" or other marking. the mark goes facing up(on both rings unless single ring piston).
rings positioned with end gaps over the locating pins(the ring grooves have a pin in them to stop the ring turning)
Piston pin clips in correctly.
Powervalve moves freely.
Again-watch when you fit the cylinder-it can be tricky to keep the ring end gaps over the locating pins as you feed the cylinder over the piston.
Hope this all helps

Am putting new piston in 200cc engine for ATV. Piston is a 63.5mm. Does anyone know the order of the rings? The ATV is a Kandi 200cc (we have never heard of this one). Disregard the Kanuni info below.

The top rings are the same it is the oil/scraper ring (if used) that is different and goes in the lower slot.
Place the gaps 270 Degrees apart and that's it.

Why is my crf450 burning oil?

Sounds like worn piston rings,oil passing rings(blow by),have to check piston to wall claerance to make sure its within spec,usually .002 to .004,if more, next size piston and bore,but if its within spec replace rings and hone cylinder to deglaze.

I am changing piston and rings, my problem is that the ring are different, do you know which one go on the top, one is more black or dark than the oder.

Most rings are marked in one manner or another. They may have a dot on them, a angle cut on the inside towards the piston, or some other means of identifying which position it goes in and in which direction. If the two rings are different, there should be a paper to tell you how they go on the piston. Since you're asking this question here, I assume that this is not the case.

I'm not familiar with Suzuki DR-Z 250. In the case it's four stroke with three rings, two compression rings and an oil control ring. If the two compression rings are the same, no bevels, no dots near the end gaps, or other markings, I'd assume that they are the same. I would install the "brighter" ring on the top as it may be either a chrome ring or moly coated ring. Make sure you check the end gap clearance on the rings and do not align the end gaps, stagger them around the piston.

After top overhaul my bike engine blow out excessive smoke and oil drip from exhaust manifold, what is the problem

Your problem is quite simple as what you done is rebuilt it with new piston rings i expect ,,but what you dident know is how to go about it SO what you have done is to fit the rings upside down ,,or ,,you have broken the new one putting it in ,,or,, you have got the wrong ring for the job,,or you dident hone out the cylinder the correct way and you took the lip of the cylinder but to much ,,or ,,the piston groove was to big alowing the piston rings to flap as it goes up and down,,and if 2 or 3 ring piston the ring gaps have to be (being air cooled) reset at 4 thou(.0004")(per inch per bore) and all rings have to be staggered,, 4 ringed piston stag to N-S-E-WEST,3 Rings in a Triangle 2 rings Opersit each other and 1 ring any where if the piston isent pined.
So let me know how you get on and work by the above and you will have a good bike again. Ron
New gaskets and (no goo ) to fit them on with and away you go
Let me know how you get on Ron

We need to order a new piston and rings kit for a 2001 yamaha blaster 200. Not sure how the measurements work. Tha calabrator is reading 66.35 on the piston and the jug reads 66.52. so we are not sure what...

take the measurement of your block.

having a smaller ring will ensure block not being damaged but prone to a Blow-By. a too-tight ring can get your block damaged. so for you to know which size to get regardless of the stock size, tyr to get the block measurement first, then off you go wich ring to get

Piston rings

First, be sure they actually do fit the bore. Take a ring and insert it in the bore. push the ring halfway into the bore using the piston. There should be about a 1/32" gap in the ring. Anything more than 1/16" and you need rings the next size up. If the ring won't go into the cylinder because the gap fully closes, the rings need to be a smaller size.

With the correct size rings, put them on the piston. Some pistons have an index pin in the ring groove Fit the gap to the pin. Put the piston mid-stroke and place the cylinder over the top of the piston. Squeeze the rings closed as you gently tap the cylinder downward and over the rings.

Please rate this solution. Thanks garethholleb!
