Top 20 2017 Suzuki RM-Z 250 Questions & Answers


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.

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!

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)

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.....

You have rust in your gas tank causing the needles to stick open. Check the filter on your fuel petcock or add an additional inline filter. Or you have worn needles in the carburetor. Disassemble clean and replace. You possibly have a malfunctioning vacuum fuel petcock that is bleeding fuel past vacuum diaphragm. Rebuild the vacuum petcock with a K&L rebuild kit or replace it with a new petcock that will also have a new fuel filter on it.

it depends on what you have for a suzuki ? if you have a road cruiser, you have to remove lower
case cover on left side of motor, this will expose linkage adjustment rod. do not try too much
adjustment, work with it little at a time. it has a wet clutch.

one bolt, look underneath the engine, could be in the middle or off to the side a bit. There is only one drain bolt, with a head size of about 14mm

I am not certain exactly what bike you have so consider the diagram below as generic. Chances are the float needle is sticking open a bit. A bit of trash may be stopping it from closing fully. The overflow hose is where any "excess" gas is dumped. This hose vents to the open air. Be sure to turn off the gas valve (petcock) at the bottom side of the tank when bike is not in use. Please rate my answer. Thanks!

Sounds like the timing may be advance too far or the carb could be needing adj.

But since its running hot first check with the timing....there may be other issues such as wear or lack of oiling causeing your problem as well

i usually adjust tension by lifting the chain from rest to 1/2 inch & when it starts to resist its at that point !
make sure you adjust both sides of the rear axle the same amount or the wheel will be out of alignment!
