Title: Oil pump options for RD350 AC
Post by: 2t Fan on August 21, 2020, 04:40:25 AM
Do we have any options here, other than a stock pump for the RD350 air cooled ? mounting points look similar on other RD model pumps  :umm:

The autolube system was similar on a lot of the Yamaha 2s bikes. The issue on some of the same pumps were they had only out outlet coming out of the pump, just make sure you get the corresponding worm drive or else it will not fit. They came out with different thread sizes and will not fit the pump.

I know that you can run an RZ pump, R5 pump, and lower displacement RD.

Not sure if you can run a Y splitter to the two carbs, but it might not be the correct ratio to both carbs.

you also need to match the gear and shaft. there were different pitches.  or, premix.

yes, the gear and shaft is a gamble. I am considering only pumps with dual outlets , the one from a RZ or LC or banshee since they are available new

rz will work for sure but you need the shaft with it.  :twocents:

No pump on a Banshee, just a breather line in the hole.

Is your bike an A or a B?  I've got a few of those pumps here and the drives. Just let me know what you need.
