Looking for an oil pump adjuster screw for my Aprilia SR 125 2T! Marsh did send me one and it was the right size but my other half has thrown it out thinking it was rubbish. Haven't got a clue what the part is actually called. If I type oil pump adjustment screw for Aprilia or anything similar I can't find the right part! If anyone has one spare I could buy or could point me in the right direction with the proper name or part number for this piece it would be greatly appreciated. Thank you in advance to any of you scooter wizards!!
