2 Strokes Down Under

I have an RZ 350 that has a 250 topend on it at the moment. I am in the process of putting it back to a 350 and noticed the flywheel has 29L stamped on it as does the cdi but that doesnt worry me but I am a bit concerned about the oil pump being from a 250. All that is written on the pump is 4L1 stamped on the pulley and the patent number. How can I check what the pump is off or is 4L1 correct for the 350.
Cheers.

250 top end 250 pump should be a red dot on it,also has a fine spline.

350 yellow dot spline is course.

Well there is some yellow paint on the pump so shes a 350.
Thanks Antman

Yep thats a 350 pump,unless someones changed the paint ID.

Wouldn't hurt to remove and give us a pic of the spline to be 100% sure.

Frame looks good ...........................who painted the casing?

Piss those black oil lines off and get some clear ones,even tank to pump then you will always know that she is getting oil.

Easiest way to prime them use them like a straw in the lube oil make sure they are longer then simply cut them back to the oil..................simple bunnings sells it replace yearly as it tends to go hard.

Use fish tank silicone tube, or silicone model car fuel line.. it won't go hard.

I am a long way from oil lines yet. My barrels are still in Germany and I only put the bottom end in because I got sick of looking at it on the bench. The casing has to come off yet, or not.
