1986 yamaha moto 4 225 squawking trans

Recommended Posts

Was just wondering if anyone has had a problem with excessive noise from the trans on this model. I picked one up for my son and did a little work on it, and have it running great but there is quite a bit of noise coming from the dual range side of the trans. Does this require oil? I look in the owners manual and could not find anything, any help would be greatly appreciated.

your engine oil works the transmission, best to use yamalube 4 or valvoline atv 4 stroke oil. given the age of the bike, it's probably do for some clutch work. maybe a new clutch and pressure plate...take the clutch cover off and jack it up securely on jack stands and run it, you should tell where the noise is coming from. in the service manual, you can only turn the clutch clockwise, try turning it counter-clockwise and if it moves, it's shot. also look at the front sprocket and the gears for wear.

      Its in pretty rough shape and its gonna be my first atv, I worked on bikes before but nothing to do with quads. Anyways the quad has some problems and im tryna figure out what to focus on first. So the U joints i think are shot. The bike starts first try every time ussually have to give it a lil gas with the throttle and revs right up, idles fine but its running REALLY rich 3 starts and my brand new plug was pitch black

      Bike is L model

      I know a lot of people say not to use anything but Oem. For the sake of the those who chose not to, or the OEM part cost more than the project, lets hold back negative comments. 
        I just purchased a carburetor that is supposed to be up to OEM specs. The company has a good reputation on eBay and Amazon. The Carb is supposed to be for this bike and jetted exactly. 
        This question should basically go under carb adjustment. I installed the new carb, the bike idles fine. On throttle it sputters half the time and the other half it will rev up fine. Does this sound like the needle is set at the wrong point? Does it sound like the main jet is the wrong size? Or is there another adjustment besides the air/fuel screw thats is 2 turns out? 
        Yes i could truck through old threads and possibly find the answer, but i thought it would be nice to have one tailored to new carb installs.
