Question about Suzuki Motorcycles
I got it given the bike by my neighbour, has no piston rings. runs but blows a heap of white smoke. is this something that can be fixed easily or should i not worry.
Piston rings are important to get the engine running properly. To replace them you will need to get at the pistons. As you don't say what bike you have I can't be more specific, With a 2 stroke it is easy, a four stroke is a bit more involved. Incidentally I doubt if the engine has NO piston rings. But they may be worn or broken. And in either case the bits from them are in the crankcase somewhere, this is not good- I would get it seen to as soon as possible.

SOURCE: 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.

SOURCE: loss of compression
Its PROBABLY just the rings, but ya gotta open it up to know for sure. If you are handy, and have a manual, you can do it, but it is tricky, especially getting the head bolts back right. The first time I did it, it took me a week, I had to consult my local shop, and I ended up blowin a head gasket cause I didnt torque the head bolts correctly

the K75 has very reliable engine .. its unusual for it to fail in this way .. the frozen rings would suggest overheating and thats possible if the radiator fan fails (that happens often before your 80,000) .. many of the pre 1990 k75s would smoke after storing for awhile .. that was a ring gap positioning problem .. that was corrected in newer models .. the smoke however would not have damaged the cylinders .. maybe in the extreme could foul a plug .. is it possible that someone put something in your gas tank ??.. or could it have been run without oil/water or perhaps the wrong type oil (like transmission fluid) ... that engine should have lasted longer than most cars .. nice smooth bike ..

IF THE RINGS ARE THE RIGHT ONES YOU SHOULDNT HAVE ANY PROBLEMS. INSERT ONE END OF THE RING IN THE CORRECT GROOVE WITH THE RING LAYING ON TOP OF THE PISTON AND ROLL IT AROUND SLIDING DOWN OVER THE SIDE OF THE PISTON. THE RINGS ARE SOMEWHAT FORGIVING AND WILL STAND A LITTLE FORCE BUT BE CAREFUL NOT TO BEND THEM.
