Boyesen Rad Valve VS V-force 3
« on: April 07, 2012, 10:02:40 AM »
So decided its time for a new reed block for my 2007 cr125, just cant decide on what would be the better choice? I have heard that the boyesen is a better reed block if you can jet it to suit, but the v-force doesnt need much of jetting change.
What do you guys use? :)

I use the v-force on my 2002 honda cr125 along with the pc works pipe and 304 factory sound long silencer I have crisp throttle responce it broadens power from bottom to top I jet the carb for what the track conditions are what the outside temp is and altitude sometimes I'll even go 1 leaner on pilot and main and put the clip on the needle in the 3rd position air screw adjustment depends on track/temp/altitude of where you are also have 52t rear sprocket. I've never used the Boysen Rad valve so I couldn't tell you but with the v-force you just jet the carb like you normaly would.

I use boysen on my 250. I don't think I can really compare that to a 125 though. But my jetting stayed the same running the boysen reeds (again not sure if that would change for your 125). They added a ton of low end and added some high end power for my 250. That they should do for your 125.

I can't speak for the Vforce, but my RAD Valve gave a noticeable low end increase and throttle response, coupled with a shorty silencer and a 51-tooth rear it shoots out of turns! Bike's an '01 RM125

Both are very good.  I prefer the VForce on 250 and 500s and the
Rad Valve on 125s.  The Rad Valve's design actually boost power
a bit on the tiddler along with the better throttle response that
both provide.

I have tried both reed blocks,my 06 cr125 has a rad valve,icat,stock pipe,pc reg. silencer, the silencer makes a tiny improvment,on a 04 there,s a big difference. The rad valve has much better throttle response, low to mid improvment is huge, threw the midrange there,s a little improvment, topend a tiny improvment. The 06 runs alot better with the r.v., with stock gearing and 170 lb plus rider, it pulls hard enough that I want to drop a sproket tooth, much leaner jetting required, the 05-07 is already very rich all stock. Pull the reeds on the r.v. and polish the inside smooth,before ya install it. I  installed the vforce on my 04 cr125 when new, throttle response is better than stock, slight midrange and topend improvment, the icat made a bigger improvment in throttle response and midrange. If your cylinder is stock get the rad valve,with the low to mid boost, it,s impossible to ever fall off the pipe. If your cylinder is ported for mid to topend, the vforce, has good dyno #,s on the topend they say. With the radvalve you want to drop a tooth, from the added boost, less shifting, let the mid pull longer.With the vforce you don,t think about dropping a tooth, because the improvment is slight.

I have always used the V-Force Reeds/cage on my bikes.  They come stock on KTM and Husky for a reason!

I run a Vforce on my 07 KX250 awesome improvement everywhere over stock
but from everything I've ever read or heard, the Rad Valve is the way to go for a CR125. Major improvements everywhere especially if you're running the FMF fatty and powercore2, re jetting is almost always required, but can be obtained through FMF website that works spot on with the RV at sealevel

If a pair of 2" brass balls isn't working, I doubt that the 3" model will make much difference.

Not saying vforce don,t work any better than stock, but most riders don,t replace there reeds every 20 hours, like you should. Then they put a vforce cage on, and they think they have this big increase in power. If they had  fresh stock reeds in, then installed the vforce cage they wouldn,t feel much of a difference. The vforce on new KTM and Husky,s  that,s just a marketing ploy. When 2-strokes where raced at the nationals, no factory teams used them. They used the stock cage with carbon fiber reeds. The biggest thing is to keep your reeds fresh, if the ends are chipped back, or they don,t seal tight, your loosing performance. If you have a over sized carb on, reeds have a shorter life span, 20 hrs  and the corners are chipped, but not all the reeds corners are chipped on the v force, that tells me the air flow is not equil on the reeds, other reeds do not seal  tight. On sleds v force blows the whole inside out, on the cage into the engine, but there pushing alot more air. For the average rider, the rad valve is the best choice because of the big low to mid increase making it easier to keep it on the pipe,keeping the rider sharp to the checkers. Corner speed is much improved with the rv, I know of other riders that tested both cages on diff makes, and 125 and 250,s same result.

Maybe the dyno imagined all that extra HP across the range I found by fitting a V Force. Petals will chip with low oil ratios the oil cushions the petal against the cage
