GY6 or GET Dip Stick Breather

Would recommend a filter for top plug!

Works like they said it would. Easy install and looking forward to my next orders from here! Thank You all!

This has helped a bit with cutting down on some of the vibration from my 150cc, it has unlocked 68 mph between 8100 to 8200 rpm and can now be ridden at lower rpms without backfiring and stalling as much whilst still running a pair valve. I highly recommend these when they're in stock they help quite a bit for being quite simple.
