This is the head i bought , its a 58.5 . I have a 2020 150cc spark with 14incb wheels. 60mm bbk, free flow exhaust , 18:36 gears, Taida high performance clutch and variator. I bought the aluminum forged clutch pully, 30mm carb , A9 cam and i also have an oil cooler.

I ended up just ordering the ncy 58.5 head. the valve springs on the fiirst head i bought had to be junk. This scoot has very good power now and i did a gps run at 70mph on a straight run. Anyone have any input on the head in the pic?

why go with an unfinished EGR head as opposed to a non EGR head?
valve springs usually break because they are too tall or the inside spring is not counter wound to the outer spring.

The uni Is huge !!. It's a lot bigger then I would normally use , but I actually kinda like it.i used 2" rubber pvc elbows and 2" pvc to connect it all. I have a 1-1/2" to 2" coupler going to the carb. 126 main jet and a 38 pilot.
