You don't have to pull the engine out of the frame to freshen up the top end. If the crank has to come out then you do, otherwise, it's gas tank, carburetor, spark plug boot, exhaust, and the clutch cable.

....and the cylinder head and cylinder. But most importantly, you need to remove the cylinder and have it honed. It is the roughening of the cyl wall that makes the rings wear in and seal. Of course, by the time you do all this work, you might consider a new piston and bore job.

Do yourself a favor tho and buy a compression tester. Then you will know for sure. It is the only way to check the condition of the rings.

to get a hone remove your cylinderf and bring it to a reputable atv shop, they should do it for reasonably cheap.

yeah i didnt see you were in ireland. i would say get a compression tester and see where your at before you do anything. then when you do freshen it up do a bore up and get a new piston kit. your probably gonna have to ship it out somewheres so just get it all done at once.

just go to an auto parts store if there are any around. i got a small brake cylinder hone to do small stuff like my old pw80's that we used to have and then i got a bigger one for stuff like the blaster and briggs small engines. they were like twenty bucks a piece. just spray the cylinder down with oil and put the honer in a drill and put it on super slow speed and go up and down in the cylinder as it spins keeping it at something between like a 45 and 60 degree angle

Yep. Auto parts store. I like "ball hones" better for just a quick roughening up. They are flexible so they get any low spots too. A rigid stone hone like a brake cylinder hone is superior for taking out more material and actually straightening a cylinder, but that takes mores skill and they will skip over low spots. A ball hone is quick and probably cheaper, too. they come in various sizes for different ranges of bore size.

Otherwise, nice description. ^^^^^ You might try googling "cylinder cross hatch" and see if you can get a pic of what it should look like afterwards.

Still, spend the $20 (or lbs or whatever) and buy a comp tester first. You are gonna want to see the before and after difference.
