Posably a bent or broken reed remove and inspect reed valve

Yes, it is a valve problem. It sounds like a weak intake valve is dishing / stretching due to overheating. The exhaust valves are made to better withstand the heat. Check for cooling problems when you replace and seat a new valve.

try tightening down your head bolts if this does not work then take the head off take the bore off and replace the bore and head gaskets and put some gasket sealent on them

pull the sparkplug[s] spray some PB Blaster inside, then let it set like that for a few days....then try to kick syart without having the ignition on...if it starts turning....then replace fresh plugs and you'll probably needs to spray some ETHER [ starting fluid ] in the intake to compensate for the oil you sprayed inside

You need to replace the complete clutch Assembly sounds like it is hanging up or something is loose. Remove it again to verify that the housing does or does not have cuts in it. This also sounds like it is stuck in gear or between gears.

If it was white smoke coming out you may have blown a head gasket. If it is water cooled and there are no signs of external leakage then it only has one other way to go, inside.
If you have an oil dipstick, pull it out and check to see if your oil looks more like a milk shake sludge. Even if you can't see it, try dumping your oil from the sump and take out your oil filter. (unless it is a 2 stroke)

your float is getting stuck open because I had the same problem.

Definitely the head gasket mate water cant really get above piston any other way - the piston would be sucking water into it on the down stroke then on the up stroke water would be passing pass the piston rings into sump oil
the only test you can do with out the bike started is a compressed air leak down test I happy to elaborate on this test if you need but if you do all your own rebuilds then I sure you know all about it..
when you take head off to replace gasket I would highly recommend you get the face of the head machined as pretty much any head that age in my experience at least would have some warpage to the face which will become harder and harder to get good head gasket seal even with new gaskets also if budget allows this would be great time to consider new piston and rings kit even new cylinder as its all apart any how if you can afford it would be very worth while
when you get running again I would also change that oil completely and oil filter every ride for at least 2 or 3 times to make sure all that water is all gone - or it will bite you later with far worse problems than head gasket issues

I don't have a solution but I do have the exact same problem, '03 or '04 (not sure) Suzuki 250 Quadrunner Ozark,really low hrs, left in storage for 2.5 yrs, gas went bad, cleaned it out, now hard to start and won't idle by itself.
I have taken the carb apart and cleaned it out, but did not replace anything, and it will still not start very easily or idle. Before I took the carb apart I thought it was flooding because it would start with the accelerator wide open, but when I would let off, it would die again. Whats going on?? I really don't want to pay to have it fixed.

2004 Suzuki RM-Z... | Answered on Jun 03, 2011


Try cleaning out first the carb. This may also be a problem with the choke and the jet for the idle. If spraying carb cleaner does not help you may want to do further cleaning by taking the carb out. You can do further inspection as well if you need parts to be replaced.

The bike has a slightly bent shift fork. The repair requires a complete engine teardown. Special tools needed include a torque wrench, impact driver, flywheel puller, and case splitter. This repair is not recommended for the novice mechanic. There are a lot of parts involved and just one mess up can force you to take the engine in a basket and plead with the dealer to reassemble the parts. The dealer will charge you more to repair a basket of parts than if you had just let them do the repair from the start. Below is a generic diagram showing how the shift forks, ( your bike has three ), move slider gears left and right to engage other gears. Please rate my answer. tombones49_122.gif

you can do it just need patience and time, if your motorcycle has more than one carburetor be sure not to interchange the parts because there are jets not in the same number. thanks!

Suzuki RM-Z 250... | Answered on Apr 26, 2011


Piston blow-by, ( compression getting past the piston rings ), is the cause. Your bike has a breather tube just behind the cylinder on the right side of the center case. Be sure it isn't plugged up and that the fitting is not plugged up. Please rate my answer. Thanks.

Getting a good connection is the problem. It just isn't gonna work. Time for a new coil. Please rate my answer. Thanks.

Exhaust Power valve setting for stock is: 1/2 turn out from closed. **3/4 of a turn for extra low-end grunt. [all varies depending on jetting selected,..start at stock 1/2 turn out ... and X-periment from there] .

2004 Suzuki RM-Z... | Answered on Apr 16, 2011


sounds like you may have broken rings and it pressurised the sump and blowing the oil up the tube

2004 Suzuki RM-Z... | Answered on Apr 07, 2011


Compare the old cable to the new cable. The outside casings should be the same length and the Inside cable should also be the same length. The dealer may have supplied you with the wrong cable. If the cable is the correct one then check the positioning of the clutch release cam.
