Title: Which reed valve is better?
Post by: supernutt on July 28, 2013, 02:22:17 PM

Got a vforce 3 valve and what I think is a vforce 2 valve. Reeds appear to all be in good shape.  Which one should I use on a well ported 250?  [ATTACH=CONFIG]1073[/ATTACH]

There are several differences between the V-force 2 and 3.  The 3 uses clips rather than screws to hold the reeds in and it has an aerodynamic insert on the intake side that is supposed to improve the flow rate.  If I had to pick one I'd pick the 3 just because they claim it represents an advance over the previous design.  You may want to test them back to back.  I've had them both and haven't notice a seat-of-the-pants difference.

Sounds like a good idea.  The 3 is newer anyways.

In banshees I know quite a few builders like the v-2's for top end performance, v-3's for lower range. Im not sure if its the same with the small design changes there would be between the quads but it may be something to consider.

I need all the help I can get for bottom end.  I weigh 250lbs and it has to get my butt moving!!!

I run the 2's seem to give a broader powerband I thought when compared to the 3's. The 3's also lost a upper reed petal on me into the motor. Hard tellin if there was a diff between the two just felt like that to me.
