Reeds are consumables, they flutter and move mere thousandths of an inch at incredible frequencies, carbon fibre ones i believe are better but not infallible.
I used to replace the petals at rebore time, now I’d say at replate time.
Price?, last time i checked around the same money ex-usa, saying that i bought mine out of italy a few years ago, and the first set had too much clearance and my idle and throttle response was crud, so i had them exchanged.
Boyeson Rad-valve is funnily enough a more direct approach in design and works much better, a larger petal retains it’s memory and is less upset but the funny pulses that (especially a crankcase Induction) 2Ts can have, they are just betterer all round.
Peter Wulfybloke, I had to rejet as the stronger signal with the V-force was stuffing my A/F ratio up, I actually went down 4 sizes on Pilot jet, and went to the JD Blue for summer, and looking at my piston wash I could go down some more… remember the stronger an engines (to a point) Vacuum signal is, the smaller the orifice needs to be to deliver the necessary volume of fuel.
BUTTTT read above, my first set was dodgy, and I’m not the only one who has noticed it.
and changing the petals on the V#s is a royal pain in the rear.
