reed valves/ opinions?
« on: March 03, 2008, 02:43:19 PM »
i did a little research with the search option but couldn't find anything real convincing towards any specific brand or type. do you guys have any tech info to support the v-force, boysen rad valve, or the stock setup as being the best choice for noticable power. or do these different types just move the power around up or down the powerband. stewart, i'm sure you've dyno'ed them all, right?

I don't have any direct experience with these two but my understanding is the the Rad valve is for top end power (drag/sand/ice), and the V-force is for everything else (MX/offroad).  I am a big fan of the boysen dual-stage reeds.  They are a low cost alternative and have served me well.  I have used them on a variety of dirt/street bikes, always with noticable results. It was the first mod I did to my K5. Cam.

I run the boysen rad valve. Its  a good reed block, but I think that I read on here that the V-Force Dyno'd better. I doubt that there is V-force II's for the k5. Anyone know for sure ? I know they have no II's for the cr-5. V-force is the popular choice.

V force works great, but don't try them nitrous application, they will not hold up.

Don,
  I am curious.  What part of the nitrous makes them not hold up. Thanks. Cam.

cam, i wonder if don is refering to the nitrous being hard on reeds because of the extreme cold tempeture of the nitrous as it exits the bottle. hmmmm... maybe, maybe not.   MADDOGGY

hmmmm....wonder if nitrous fed combustion pulses the reeds closed just as hard as it forces the piston down?

First off I'm real leery of any one selling a part that fits a 2005 model KX500.  They quit making the K5 in 2004.
Their quads and sand buggies look like they are made in China.  All China bikes, quads, and sand buggies I have seen are junk.
If they can sell a China bike to a person, look them in the eye and say they got a good deal.  I would question their integrity.

I'm not sure what happened but two runs and there was only 1 pedal left on a brand new cage,not one side, one petal, needless to say it never went back in. I think I still have it, I'll get a picture and post it, total destruction. I don't know if it was the cold or the fact that there are no reed stops or what, the Bousen dual stage carbon reeds hold up, don;t know why the V force won't. and as for the question why nitrous :?, I guess because I can, there is no such thing as to much power. somebody said why did you buy a 500 and his response was because they don't make a 600 :-D
