Review on Upgrade Your Yamaha Jog 50 Scooter With WFLNHB Intake Manifold Reed Valve Assembly Replacement For Optimal Performance by Alex Tellekson

Fit the same as original parts.I rode it for about 20 minutes then adjusted the air screw in 1/2 of a turn.Also used permatex 90 minute gasket maker sparsly on the outer eadges of reed valve top and bottom outer rim.Lock Tight mid strength on the manifold bolts and card jet screw after adjustment of the air set screw and bolts.Anything with high vibration 4 stroke and 2 stroke bolts become loose even with lock washers.Mid Lock Tight on bolts saves me a lot of work.
