Question about Yamaha YZ 250 Motorcycles

2 Answers

Hi, i have a 2001 YZ250 and have been having a slight problem at low revs, when i open the throttle up there seems to be a slight delay on speed pick up, this only lasts about 1 second and once ive reached mid range the bike is fine, however once i drop back down to low revs the same thing happens again. any solutions to this will be very welcome

If you have added aftermarket pipes then you could have a fuel mixture problem, or even dirt or grime in the fuel path, I would either rejet the carbs or I would do a good fuel system cleaning.

Why does my honda foreman 400 shuts off instead of idling.


It could be your idle speed is set too low. If it will run with the throttle slightly open and rides okay with the revs kept up I would try increasing the tickover speed and go from there.

The engine misses on acceleration above 6K revs. New spark plugs Air filter fitted. Carbs cleaned. At low revs and speed engine is smooth. On acceleration appears to die and pick up againbut worse as...


what kind of bike is it?what style of carbs? if it has rubber diaphragms in the tops of the carbs, you might have a pinhole in one or more of them.

Aprilia RS 125 Power Loss


I guess youwillhaveto adjust the clutch cable so as to open the plates more at the pressure plates to let the clutch plate rotate freely instead of binding thus the low rpm.
Hope this helps!

Your carb may be adjusted a little lean. Try adjusting the needle, keeping track of the changes you make, and blipping the throttle full to check the result.

Idle speed engine dies when throttled


It does sound like its getting to much fuel, or the lack of air. Air filter ok? If it is you might need to have a compression check done to see how the piston rings are.

Honda CR125 Motocross bike throttle delay


ALWAYS have a fire extinguisher on hand when working on carburetors.
Drain the carburetor. There should be a screw on the lower side or bottom of the carb float bowl. Remove the screw then replace it after the fuel drains. Turn the gas back on and wait a minute for the carb to fill with gas. Now pull the top cap off the throat of the carb and remove the large slide. There will be a long needle in the center of the slide. Remove the needle and then move the clip at the top on the needle down one notch. Two notches may be required but start with one notch. Put it all back together and try it out. Moving the clip downward richens the low end fuel mix.
