there is a sight glass on the foot brake side of the motor
About 1 quart of gear lube
Synthetic lube
A Yamaha Blaster not going into gear is typically a sign of an issue with the clutch. To troubleshoot, try to adjust the clutch at the lever. If this doesn't solve the problem, the shot clutch pack may need to be replaced.
its right by the gear shifter kinda under the frame
should be alittle more than a half of a quart
Because you have a seal that needs replaced. Some where on case causing it to leak gear lube.
10-40 light gear oil ,any good make will do it takes 650 ml once drained
Does it have gear lube in the case? If so you will need to inspect clutch basket may need new clutch or clutch springs may have failed
right side crank case
how gear are shifted in Yamaha FZ byk
My son has a 2005 Blaster set up for racing. We usesynthetic gear case oil. That's how its labled on the quart bottle on oil weight on it. Dont use regular car motor oil because it does not lub clutch correctly.
