1974 Yamaha RD350 Timing and Autolube

Hello Everyone,

Newbie here with a '74 RD350 fouling plugs. I've been reading on this site about the importance of setting the timing and making sure that the autolube is adjusted correctly for this situation. My knowledge of setting the timing and the autolube is very lacking. A dial gauge is in the mail and I've got a makeshift timing light on hand. Can anyone tell me how to set the timing and adjust (make sure) that the autolube is correctly working?

Thanks a million.

Thanks JohnnyCash,

I just took a visit at 2strokeworld.com and the timing instructions. Great info! I'll give it a try when the dial gauge gets delivered (probably tomorrow). But, I didn't really find info on the autolube.

I was just concerned that these instructions are general for two-strokes and not specific to the RD350.

Cheers,
You can verify that it is pumping oil by removing the bleed screw on the pump. Take the oil pump cover off then run the bike with the screw removed. At idle it will move some oil, if you rotate the plunger around to max stroke it should drip out at a pretty good clip.

As far as adjustments the book says to adjust the stroke of the pump. You do this by adding or removing shims. You need to rotate the pump to full stroke then you will see a small notch on the pump pulley. The gap between that and the pump body should be .040" I think. If you want I can check later.
