Question about Honda XR 200 Motorcycles

Honda XR200 revs up and down while in high RPM or higher speeds

Hi, I have a 1994 XR200, I got the bike from my older brother (hadn't been run in a few years), after changing fluids cleaning the carb the bike ran terrible. So I worked on the carb, the idle is now great the mid range is great but in high speed or high RPM the bike revs up and down. I took the carb apart cleaned it and made sure I did not miss anything. I took it for a test run but bike is still revving up and down at high end. I have been cleaning everything and working on the bike for about a month. The only thing I cannot fix is the Revving up and down at the high end. What could it be?

You are on the right track with the fuel system. Maybe the fuel filter, There is one in the tank also, I think. Try running on reserve if you have it.

when you cleaned the carb, did you remove the jets? Sounds to me like the high speed jet is plugged

Sounds like a fuel problem, possible stuck needle valve. Did you check for vacuum leaks? How about the fuel itself, did you treat it before storage to prevent gelling and varnish ? If not your entire fuel system may be restricted. Purchase a can of Seafoam...pour in 1/2 of it to a tank of gas, use the other 1/2 on the next tank. Change fuel filter afterwards because any foreign materials will be in the filter from the cleaning process. Third tank normal fill.
Good luck...i hope this helps.

SOURCE: took apart carb cleaned and now there is no mid or high range

did u install new gaskets, the engine might be sucking air from outside the carbs. u can use a propane torch (not light) spray a little around outside of the carbs, see if engine sounds different, if it does... leaky gasket.. u might check there is no unplugged vaccum hose.

Honda XR200 Revs up and down while in high rpm and high speeds


Hi, Worldrand if your bike has been sitting idle for months or years and you did not do any pre-storage maintenance I feel your pain it will probably have a dead battery and not want to start or if it starts it will idle and run poorly then stall, here are the following steps necessary to complete in order to get your bike back to an acceptable running condition and in the future pour in a bottle of fuel stabilizer and injector cleaner for you FI folks at least 2 times a year and before storage.
1. If your battery was 2-3 years old when you last had the bike running you should replace it.
2. If you believe your battery might still be serviceable remove it from the bike and put it on a 1 or 2 amp trickle charger for 24 hours. If it is the old lead acid type with visible cells and acid levels fill each cell to the top line with distilled water and replace the caps, run the vent tube into a plastic or styrofoam cup, any cells that are cloudy/milky replace the battery.
3. After charging remove the leads and let the battery sit for a couple of hours then check the battery voltage with a volt meter, you should have 12.5 volts or more, any readings in the 11 volt range you need to do a proper "LOAD" test on the battery and replace as necessary, you may have 12.5 volts or better but little or zero amps, any readings in the 10 volt range you have a dead cell and the battery needs to be replaced.
4. Drain and flush fuel tank, google " how to clean a motorcycle gas tank" find a couple forums to view the different options available.
5. Remove and inspect your air cleaner paper elements that are not oil soaked can be cleaned with a soft brush and low pressure compressed air, oil soaked elements must be replaced. Gause mesh and foam elements can be cleaned by soaking them in a container big enough to completely cover them with a solution of 1 gallon of water and 1 oz. of Dawn dishwashing liquid for small and medium size elements, for monster size double the formula and let soak for at least one hour then rinse with warm water shake off excess and let air dry, "WARNING" do not use compressed air as this will embed micro-sized dirt and road grime and destroy the mesh pattern and stretch foam elements out of shape just squeeze it like a sponge and let air dry, use a fan if you're in a hurry. When completely dry spray a very fine mist of air filter oil evenly around the whole element.
6. Remove the carburetors, disassemble and decontaminate with a carb dip or if you have EFI remove injectors and clean with carb spray and compressed air
7. Check intake manifold and seals for leaks and cracks.
8. Remove fuel valve and filter disassemble and clean as necessary, remove, clean, and inspect fuel and vacuum lines and replace as necessary.
9. Replace spark plugs with new ones and check for spark.

Struggeling so switch gears on high revs


You could have either have the clutch not adjusted correctly or you could have glazing on the clutch discs or both. I would check for glazing on the clutch pack.If they seem glazed rub them on the cement a few times. The concrete will not harm anything but it will clear the glazing off of the clutch pack.

Why does my DT125 splutter at hight revs


Sounds like either the bike is starving for gas at higher RPM's, or you're hitting the rev limiter.

125 DT Yamaha won't rev up in higher RPM


Hi, Anonymous and the usual suspects are:
1. Severely drained or faulty battery.
2. Faulty regulator/rectifier or high output coil.
3. Faulty power valve, solenoid or installation.
4. Clogged air filter or exhaust.
5. Cracked or incorrect float level.
6. Float needle is not seating.
7. Faulty reed valve.

Will not rev over 8000 rpm


This is hard to tell without riding it to feel the condition. Here are a few things that come to my mind.

1 Spark plugs or ignition system not able to handle the higher demands of the higher RPMs

2 battery or charging system not creating enough power to meet the higher demands of the bike (ignition and fuel systems)

3 Fuel flow to the carbs is low or the main jet is clogged.

4 valve adjustment and or valve timing

CBR 400 NC29 not pulling through rev range


The carb has serveral jets for different Rpm ranges. If you have a problem with one range, that specific jet is probably blocked. Idle jet, low jet, intermediate jet, high jet. some bikes have more. Sounds like a jet problem to me Run Seafoam cleaner in a couple tanks.

Rpm


This is actually designed to run at those revs. It\´s basically the best way to maintain reasonable power to wheels at high speeds with an engine that is not powerfull enough to produce the HP needed to maintain that speed or higher speeds with a higher gear ratio.
