Ok, so I wound up getting a Taida 4 valve head.... So here's the deal, they only sell an EGR equiped Valve cover while the head is a NON-EGR, at least as far as I can tell.... First pic is a stock GY6 150c , 2 valve head showing where the port is supposed to be.... Next two are the Taida 4 valve head and the missing port. (*note, the EGR valve and pipe you see on the Taida head did not come with it, it's one I stripped off a GY6 head I had laying around.)    ------------------------------------------------ Extra non specific data --- The 4 valve head is very nice! .. The mold is perfect with no flashing... This is a one of a Kind, Taida machined this Build to spec.... I have a +3.5 stroker for it with an extra tall water cooled 63mm ceramic coated cylinder (69.5 tall), 4 valve forged piston. It's going to wind up being a 191cc that's fuel injected. |

Not a problem you can just take the Valve off the Valve cover and your done. You see the two screws holding the valve to the valve cover take those two screws out and the valve and all you will have is a piece on the valve cover that holds the actual valve. Alleyoop  For a cleaner look you can saw off the Valve Holder from the valve cover. |

The Taida valve cover did not come with the valve/cover/pipe...That was something I stripped off a head I had laying around just seeing if I could find a different spot to hook into the head.....Possibly cut the EGR pipe, flare it and tap the head elsewhere.... But I think that's impossible without milling an EGR port into the head??? I know a lot of people kill their EGR's, I was wanting to keep my scooter PAIR system compliant so I was street legal in all 50 states...... |

tap into the exhaust header just after the flange and plumb back to the valve cover? ..Or remove the system all together. It robs powah!

"I was wanting to keep my scooter PAIR system compliant so I was street legal in all 50 states..."
Which states require emissions testing on motorcycles or scooters? I can't find even one state near me that tests motorcycles or scooters. Looking at google, I could not find ANY except for maybe CA (looks like AZ used to test, but no longer).
To me, it looks like most states are set up for OBDII testing (they plug into the OBDII socket to check your onboard computer), and that most tailpipe-based emissions testing is gone.
