what have people triend and what are you guys using?

 

Id put my $$ on something else, reeds arent noticable power-wise, and rad-valves are too expensive for the little amount of power the give....

 

if your going to spend the money on reeds.....i wouldnt buy anuthing but V-force reeds....they are the best in my opinion!

 

For stock port designs the V-Force work great but on a ported motor its very risky to run a V-Force system for the simple fact that the their made out of plastic. Not only that but the actual reeds themselfs wear and fray very quickly on a ported motor and at 50 bucks for the replacements that can get expensive very quickly. I had my last Blaster top end badly damaged because of a V-Force system. I had just replaced the reeds and after about 15 hours or so on my brand new ported stroker motor two of the little reed screws poped out and got sucked into my cylinder causing damage. And yes I used loc tite as recommended and no they werent over tightened, the plastic unit just could not hold up to the power. Also, after that 15 hours the reeds themselfs were already frayed and worn which at 50 bucks a pop for the replacements thats not to cool.

The design on the V-Force works great but the cheap materials that their made out of badly compromises the stabillity of the unit. For my money its the Duncan Racing Pyramid reed valve all the way.
