ex 440 chain case oil

[jeffro9]

does anyone know how to change the chain case oil on a 1979 exciter 440, does the whole cover have to come off?

Yep. The whole cover has to come off. Drain, clean the crap off of the bottom, then replace the cover. Either replace the cover gasket or use some yamabond4 on the mating surface. Fill the case with chain case lube, gear lube or ATF. There is a plug in the case in front of the foot well. Fill until the oil starts to weep out of that hole. Replace the plug/bolt and ride. Enjoy.

yes must remove the cover ......SAE 10W30 is what Yamaha calls for 320cc of oil or 10 OZ.
