carburetor I forgot to put the Spring of the Pilot screw at the time of cleaning, I loosened while driving, dropped off OEM's Pilot screw somewhere in Japan and I could not Idling, I thought about looking for OEMParts already in the Manufacturer Parts supply is also finished, OEMcarburetorPD 52 same etc. I bought this product which is Pilot screw of PD22 carburetor of goods.
Adjustment Screw I thought this price was one ... but no special tool required. What you can adjust with your fingers
Larger than the standard return amount described in the Service manual, the number of revolutions increased and the Idling became very stable when turned to bold more.
Wasted old motorcycle etc etc. It seems there are times when you need to make adjustments, so I think that I was glad I bought it.
