Air filter for 1981 cr80r dirt bike? - Motorcycles

Intro: How to Change the Air Filter on a Dirt BikeThe air filter is one of the most important components on an off-highway motorcycle. The filter captures dirt and debris and keeps it from getting sucked into the motor during operation. This can be problematic for two reasons. First, dirt and debris causes excessive wear on the internal moving components of the motor, such as, the pistons and rings. Second, a clogged filter allows less air into the motor, which will result in sluggish performance. This maintenance task is very simple. With the aid of these instructions, even a beginner can do it. The entire process takes between five and fifteen minutes.

The carburetors need to be cleaned most likely clogged jets and passage ways.the low speed jet is what you want to pay close attention to make sure the are clean.
If you are going to do it yourself pay close attention do not mix up the carburetor parts always lay out the parts from each carb in the from left to right 1234 separation.
I suggest you get the service manual fir this bike before you attempt doing the work yourself.

not enough to go on, but these were not slow bikes. try plugs, mucky carbs, carb jets, air filter.... take out plugs, any dirty black while others are clean or white? start bike from cold, run very short while and turn off. carefully feel exhaust pipes at top, are thay all same temp? one or two not getting warm? watch you don't burn your hands....will tell you if all cyliders firing ok.

hi 81 yamaha i am concerned about the fuel smell coming out with the oil. could be the carbs flooding filling your crankcase with fuel? if not it sounds like you have blow by which would cause your crank case to be slightly pressured. this is caused by worn piston rings. do not plug your crank vent. if you leave your vent open install small filter to stop dirt from entering jim
