Over here (In sunny :roll: Britain) Boyeson is a name we trust so I have been tempted by a Rad valve but a lot of you are running V Force reed blocks, now as I run this bike on the road I am quite fond of topend poke with a bit of over-rev for it.
Have any of you tried both and what did you think?
As they are both fairly spendy I don't really fancy getting something that turns out to be a bit crap.
Thanks very much regards Scott

Howdy,
I bought the rad valve mostly because it comes as a complete intake assembly (my rubber boot is shot). They come with two stage reeds which are probably better than stock for bottom end. I think I'll also go with 14/48 sprockets to help a little with the bottom end.

i think you will be happy with the rad valve.it does pickup the top end and will do more if slight mods are done.this is along with proper gearing though.

As said above rad valve is more on top,the V is broader.

Personally, either reed setup would be great since they are both Carbon Fiber and will last/perform longer than stock.
I use the Boyesen Rad Valve because it comes with an aluminum body that replaces the stock rubber boot. It has a smaller rubber connector that has less contact with the fuel which cause rubber breakdown.
The V-Force requires you to modify/cut/trim your stock rubber boot to mount up the reed block.
With carbon fiber you can pull the reeds and flip them over every season/year of riding so as to reduce the fatigue/memory factor with the reeds bending during use.
