Title: Yamaha Autolube
Post by: XR on January 11, 2010, 06:29:21 pm

Hi, I want to run pre mix on a Yamaha MX 360. Can someone please tell me the procedure for removing the autolube pump. And also with the decomp cable, do you leave it in the crank case disconnected or do you remove it and plug the hole with something?

Remove the clutch cover and remove the oil pump and drive gear from the cover and block off the hole were the pump screws to the cover, silastic the hole in the rubber gromet were the oil lines go into the oil pump cover, block the oil feed hole with a 6 mm bolt in the barrrel, replace the throttle cable with a YZ cable, remove the oil tank. and oil feed lines, rejet the carb and leave the decomp cable conected, I run my MX 360 at a 30:1 fuel ratio. ;D

Thanks Betric,  I have removed the pump and the drive shaft which came out as a assembly and has left a sleeve in the case. Do I plug the sleeve or remove it and block off the hole with a plate? I am guessing it needs to be air tight?
Do you use the decomp or are you suggesting just to leave the cable there.

Good question XR,
I have to sort out my MX 360 in the next month or so.

I have left decomp connected, I dont think it does much though, just make sure that the decomp assembly is tight in the barrel as I have had it unscrew itself out of the barrel on my bike.
