I am thinking about going with a 330 kit on my 89 R. What reed cage do you guys use for GNCC/woods racing? Most likely it will be an ESR 330 kit with the TRX7 (low-mid) porting.

1. Boysen Rad Valve
2. 2000 CR 250 reed cage

The CR would be better for you. It has excellent bottom end snap.

yeah cr250
the rad valve is more of a top end reed valve

the cr 250 boysen "rad" reeds w/38mm air striker is working great on my ESR 310 PV motor .. love it ...has bottom end and screams on top
