On a 95 suzuki king quad 300 do u have to break the engine in half to replace the piston rings


The valve train, head and cylinder must be removed from the transmission, possibly even the fuel system. You should replace the base gasket as well as the head gasket while reassembling. Be careful to not let the timing chain drop into the transmission and make note of the timing marks as well prior to disassembly. Tie the chain with a string while you slip the cylinder off the piston.

Have oil in one of the spark plug cylinders what would be causing this ?


broken/worn piston ring(s). Each piston has 2 rings. These can be replaced by the DIY mechanic by
1) removing head of engine (remove head gasket - you'll replace it), then
2) manually wind the engine (with a ratchet wrench & socket) til the piston in question pops up
3) remove both rings (with ring pliers - available from any auto parts store)
4) install 2 new rings (with a ring installation collar - available at any auto parts store)
--- choose ring installation tool to the correct size for your pistons.
5) re-install head of engine (replacing head gasket)

Note that this procedure preserves the engine timing, so you need not reset it.

what I would do is buy a timing chain kit and go look at a service manual at a library or buy one on ebay. put the new parts in and set the timing marks in accordance with the manual. if the engine is interference type, you probably are going to need new valves and a used engine with lower miles would make more sense than doing a valve job on a 20 year old engine. interference means the valves and the tops of the pistons occupy the same physical space, albeit at different times, so if the timing is out the valves are bent.

Hi I am doing a simpile head & cylinder inspection. Just bought the bike smoking bad. The cylinder & piston are damaged. I will be replacing piston rings & doing a bore job to match new piston....


The diagram below should work for you. Put the piston on TDC. the OHC cam gear will have a single mark or may have two marks, see below. Be certain the front side of the chain is taut when mounting the gear. The cam chain tensioner keeps the back side taut.

1985 XR 200 ALL TIMING MARKS SEEM TO BE RIGHT, HAS FUEL ,HAS SPARK .BUT WILL NOT START


By "all timing marks seem to be right", are you talking about the timing marks on the alternator rotor or the camshaft timing marks? A 1985 model is a pretty old bike. If it has never had a timing chain or the adjuster guides replaced, you may need to address this issue. Not only do you need for the ignition timing to be correct, you need the camshaft timing to be correct as well.

In your problem line, you stated that you had fuel, and spark. You need three things to get any engine to run, fuel, spark, and compression. Do a compression check on the engine. If the compression is low, it won't start either. Three things can cause low compression. Bad rings, improper camshaft timing, and valves not seating properly.

If you want to get the bike running again, I would suggest you do a "top end job" on the engine. Pull the head and cylinder. Measure the cylinder for wear and bore for a new piston if necessary. Replace the rings. Have a valve job done on the head at a local machine shop. When you put it back together, do so using a new timing chain and adjuster slides. You'll be surprised at what a "New" engine feels like. Good Luck!

Timing chain 110 hymoto pit bike


Put the piston at TDC (Top Dead Center) by lining up the timing marks on the flywheel and stator. Put the cylinder head back together with the cam installed so the high points of the cam lobes are pointing kind of downward. Pull the cam chain taught on the front side of the engine. Put the chain on the cam gear such that, when bolted to the cam, the index mark or marks are in the proper position.

The proper position depends on what markings are on the cam. Some bikes have a single mark; an arrow, a straight line or an "O". The mark should line up with the center-line of the crankshaft. If the cam has two marks opposite each other, the lines should be parallel with the gasket surface. You will need to rotate the unbolted cam left or right just a bit in order to match up the bolt holes to the gear holes.

Can I get a “very helpful” rating on this answer?
