TE/TC Rad Valve 42-E

Any of you guys get one yet for the 17+ 250/300???

If so, thoughts? I have one in the box, but also have the VF4R already mounted...

both of them are top tier products the choice is the choice of what brand and setup you want. cant lose either way.

yeah, true. I may run the VF4R for now since it is on there, then give the Rad a try.

How about some pics of the RAD. Cam.

Well the VForces leek air. Sooo........ Tell me that the rad valve is an aluminum body and not plastic??

Ummm... Do the reeds seal air tight on the VF4? Or better on the Boyesen?

Boy that rad valve is a nice looking setup. I wonder how it would fit with a Lectron.

As Motosportz reiterated from many top tier tuners, the crankcase vacuum of the piston going up opens them and the crankcase pressure wave for transfer will close them....remember this is the reed pedals slamming open and shut at 1000s (rpm) of times per minute or if you want to do math for about 83 times per second at 5000 rpm.......OK yes if the reed is cracked and has a big leak or completely unable to seal even under a wave of pressure, you will have an issue. All this internet stuff about seeing a sliver of light is way down on negligible scale in regards to reed valve tech and engineering. And yes fact is they should be sealed in static position, and yes the OEM sets are prone to being sliver of light open. As mine were, the key to the Rad and the V4 (V3) is that they are built to a higher degree of spec not cheaply mass produced as the OEM units are. Additional my 14 TE300 and 17 TX300 both ran.run better with V4 reeds in them along with proper tuning. Both of these top tier products are used on top tier tuner bikes, they dont arbitrarily leak, thats mostly or if trend analysis is done found to be caused by the non top tier installers in their garage, no doubt.

I've also heard of VForce systems leaking around the boot. Never heard of them having leaks at the pedal/cage interface like the newer KTM/Husky OEM ones. The boot leaks, as you know, are easily fixed with some gasket maker. I use yamabond on both where the reed cage goes up against the cylinder and where the boot goes up against the cage.

I would also like to hear which works better v force or rad valve. Kinda like Rad valve looks better, I am still running stock reeds at 85 hours and doing winter tear down and top end rebuild and thinking about changing reeds while I am at it but have heard it not worth it other say it is. My bike pulls hard never stalls with just jd jetting kit and sx head mod that it so far. Compression test show like new still but new top end would be cheap insurance for next year riding.
