Refilling Italian Oil pump

[burnt_toast]

I've recently done some major work on my Italjet Formula50 to get it running once again and it involved taking off the reeds and draining the oil since it was pretty old. This also meant I had to take the case and subframe and all the tricky panels off.. pita lol

It's since back together w/out the panels and I refilled the oil tank with oil and let it start seeping down the line by disconnecting it at the pump then reconnecting once fresh oil reached the pump area without any air bubbles.

I'm happy to say that reeds where the culprit and hopefully I can get this bike back on the road, made a nice big smoke show last night. o_o

But as far as oil pump, is there any thing I should do to prime it? Will it naturally start working by itself? I've also added about 35oz oil to gas and now using full synthetic since it looked like cheap generic stuff was in there.

Crazy Scooter, Overrev and other Euro guys what do you think?

As far as it goes with priming the pump you've done it all correctly imo. Step 1 is purge the tank to pump line. step 2 is remove oil line from carb and wait for it to purge with motor at idle speed. However as long as the input oil line to the pump is totally empty of air and full of oil and you have premix in the tank then it should self prime. Just be sure you check the oil is to the carb before you stop using premix.... Oil won't come out fast but it will be enough.

See its actually an interesting setup, the oil feeds directly into the case and directly into the reed block via two separate feed lines after going through the pump.

Thanks for confirming the fill method. I will double check for air today and hopefully there will be no bubbles.

The oil line is completely filled, and the bike smoked up a lot on initial start up but after riding the smoke clears almost completely.

Is there anyway to check/be sure the oil pump is doing its job? As in would plug read or temp be a good indicator? Would it run too hot if its not being oiled enough?

I just want to make sure the injector is operating correctly and not worry about running without oil and seizing up.

Thanks

BUMP anyone? ..pray..

I would run that 10 year old with pre-mix only...but thats me.

hah man.. thats what I keep thinking in the back of my mind too! But the fuel tank is huge ~2.5-3gal so mixing enough would be a pita, and the oil injection system is actually supposed to be very good, running off engine rpm rather than cable controlled. It is also injected directly into two ports on the reedcage rather than spit into the manifold carb side.

My ideas so far.. draw thin line on tank and see if I can visually see depletion after xx miles, and plug check often. Any other ideas welcome too, come on overrev and crazy scoot, what are those euro tricks? lol
