20 Most Recent 2012 Suzuki RM-Z 250 Questions & Answers

It sounds like you have a problem with fuel starvation. Check from fuel tank to carburetor. Tank may have sludge in it, shut off valve may have clog or rust, fuel lines when old tend to collapse in on them selves, filters clog or become dirty, and carburetors tend to accumulate dirt, water, clogs, and may need to be rebuilt. Since you are running fairly well, your problem may be small and inexpensive. GOOD LUCK FRIEND.

Carb is not a pump. Carbs depend on suction and pressure to operate. If you are not getting fuel, the fuel pump may not be delivering the fuel to the carb or the carb may not be allowing the fuel in due to a stuck float valve or a dirty jet. I'm leaning toward a dirty jet or bad fuel.

so here is the answer straight from the manual:

Intake: 0.09 - 0.16 mm (0.004 - 0.006 in)

Exhaust: 0.17 - 0.24 mm (0.006 - 0.009 in)

this particular year was very unusual because it removed the multiple inputs from magnetos and just went with a single (2 wire) signal coil (green, black) which will ultimatly go into the left side case behind the pull start. the white/blue wire goes directly to the coil. the orange wire goes to the ignition and will have 12 volts when the ignition is powered on, then go to ground with ignition off. the black/white is constant ground. this year was different because the cdi let the regulator do all the converting from ac to dc. it is also one of the haardest years to find a box for used.

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!

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.

Possible you ran out of fluid before refilling...or maybe didn't get bleeder closed tight when you released brake pedal, and some air got in the lines. I'd just bleed it again.

Yes, it sounds like a complete engine gearbox strip!

you may expect no lower than 10 hours because you have to remove motor and dissasembled and you may expect to reshim a valve or two that is too tight at the same time.....we rebuilt a kx 250f 2008 last week and rebuilt the crankshaft and change valve guide and reangle valve seat for 12 hours r&r.....
