SOURCE: engine miss at 45-55mph, no accleration with throttle response,

Anytime a bike sits for that long you stand a chance of fuel system problems. It sounds like you may need to "boil out" the carburetors and of course resynchronize them with vacuum gauges when you put it back together. You can also use a mercury manometer for synching the carbs. My guess is you have varnish still in the float bowls that is causing erratic running and perhaps the vacuum operated slides are not working correctly.

SOURCE: 2003 Yamaha wrf 250 only runs with the choke on

possibly water in your fuel.... it's a small tank so just put about a quarter bottle of gas line antifreeze in the tank... it's alcohol so it will **** up the water. there is also the possibility the fuel is somewhat dirty... change the fuel filter as well

SOURCE: Rusty Injectors

you going to have to pull the injectors out and clean them. You also better see a bout buying a type of tank coating that you pour into the tank to stop the rusting, or you are going on have this problem with it stopping up your injectors.

SOURCE: 2003 yamaha wrf 250 carb problem

(1) You will need to adjust the float pin to get the correct amount of fuel in the float chamber of the carburator.
(2) You will also need to set the air-mixture screw , but before you do tht remove the spark plug and see whats the condition of it, is it black , is it brownish, or is it whitish.
If its blackish = means rich too much of fuel, if its browinsh= ok, if its whitish = its too lean.
(3) As for hesitation, check the needle at carbs piston on the accelerator cable, and blow the main jet with high pressure.
(4) Check too the spark plug gap and if its as per the manufacturers specs.

Hope this helps!

Why is my idle so high? What else could be giving the P0507 code? What am I missing?


Remove the EGR valve and inspect the pintle for debris ( chunks of carbon) hanging it open , this will create a vacuum leak and cause a higher than normal idle.

Add some sea foam in the gas tank. Leave in idle run for about 5 to 7 minutes. Then idle the rpms up and watch the white smoke choke out. Which will clean or attempt to clean the throttle body out

At times my car idels a little high and when you let off the break it accelerates by itself more than normal


this is a pretty common thing,, when applying your breaks , the brake booster requires more vacuum to work, which takes the vacuum from the motor,, once released the motor gets the vacuum back,, so it will rev up a little, If your familiar with working on cars, remove the throttle body air duct,, spray a little carb cleaner ( a little not a bunch) into the end of the throttle body opening, there is a governor plate inside that gets gunked up, and will make the cars idle jump around at times, clean that and you should be fine !!

Just need to adjust the carburetor, H & L not idling properly and now have got both of them out of adjustment. Have cleaned the air filter. Please help


start off with basic settings of 1 1/2 turns out on both of them, then adj the "L" which should be closest to enjine to where you give it throttle it does'nt boog down on acceleration then get ready to adj the "H" which is closest to air filter, keep in mind you should always have a new spark plug and new or clean airfilter on the machine before attempting to adjust it, so anyways bring your saw to full throttle and adj "H" to where it 4cycles just a little, in otherwords run it in a little till peak sound(rpms) then back off till just is on the edge of slowing down or garbling a little. then go back to low speed and make sure it is o.k. then cut some wood at full throttle and see if maybe you can open it up some more with out loosing power. remember a hair rich is better any day than a hair LEAN! Good Luck 2StrokeJim

How to i adjust the idol speed on my 1985 cutlass supreme? I do not have a gauge for rpms.. but it just sounds and feels to high.. i've cleaned the throttle body and everything.. what piece do i turn or...


On some models the TBI cannot be adjusted .Usually these functions are carried out by the Idle Air Control valve ,the Throttle Position Sensor and the power control module.Any kind of adjustment will cause false signals to the PCM.I would take it to a local mechanic and have him test your rpms at idle that will give you a rough idea where running at.That way you can find out what the recommended rpms are and see where you stand at that point.most of this can usually be tested at your local autoparts store depending what area your in.

I recently purchased a 2002 lowrider with only319 miles on it obviously it has sat awhile. It has a hard time idling on initial warm up and when warmed up giving it a little throttle (not under load) it...


The bike may suffer from a combo of the gas going stale in the carb, and may have slightly clogged the small passageways, but if it starts and runs you are halfway there. Use some carb or fuel injection cleaner in the gas tank to help out there. As far as cold start, it may be from a lean condition form the factory, and the coughing and popping are symptomatic of that. If you have a good HD shop nearby, they should be able to change the slow speed up just a bit, to pretty much take care of the issue of coughing, popping and cold start issues. My bike was the same, I bumped the low speed jet up , but still have a cold blooded bike, it takes a while to run properly form cold start, and will pop if driven too soon or if it is cold out until she warms up good. Some advice for cold start, use the choke know as usual, then push in the choke as soon as you can, and use the throttle to keep RPMs up about 1000 using throttle lock to RPMs there. As the motor warms up RPMs will increase on their own and you can adjust the RPMs lower as motor warms using throttle and throttle lock. Use your hand to touch the heads, as the motor warms up you'll feel heat, when she's too hot too touch, she is ready to ride. See you in the wind.
