On my 250 , I'm going to end up replacing the reed / cage on it and wanted some opinions on what you guy's though. I have the V-force on my 125 , which was way better than the stock crap that came on my bike. But for my RM 250 , I ordered a V-force and it was total crap compared to my stock cage ( with replaced reed pedals ). There was a big difference on quality between the cage setup I got for the 125 , compared to the 250.
So for my TC 250....Should I get another V-force , or try out a Rad Boyesen Rad valve?

Me: Is the Radvalve better on YZ250 then my Vforce?
Tom Morgan: "The VForce is definitely better. I am 100% certain in my dyno and track results."
Other parts I have in mind are a lot like what I did to my 125 , which I'm super happy with because it freakin' rips! But what I have planned is definitely the reed cage , and then I'm taking this Mikuni off and getting myself a new PWK 38 , along with a Derek Harris STIC mod. I'm also going to get myself another Scalvini pipe ( because i simply love the two I have for my 125 and RM 250 ). The silencer.......probably another FMF 2.1 powercore , but not 100%. I have to check the Squish on this thing , but I will probably mill the head slightly. At this time , no plans for any porting. And other misc things are a new aluminum throttle tube and a taller seat. There will be other thing's here and there depending on how I feel on her.
try pm'ing here..I would gladly send the Rad Valve out to you.
I’d definitely go with the rad valve, as I feel they put more R&D into individual years. People using the V-force on the YZ is really a mute point because that bike hasn’t changed in over a decade and a half, and all parts for it are on point at this stage.

The 1st time I tried them back to back was in 2001 on a CR250 & ended up sending the Rad Valve back to Boyesen. I've used the V-Force on a couple of different models & prefer it due to the mid-top being enhanced. They're not major gains, but slightly noticeable with good jetting specs..
I'm about to start riding/building a 2017 250SX. I'm going to start by sanding the reed block to improve the reed seal.
If you search youtube: 2017 KTM 250EXC Tokyo Offroad, they talk about their setup. Very informative.
FYI, there are a lot of threads about this topic, and sadly, there are a lot of guys that say the V4 or the Radvalve doesn't do anything for our bikes.
Old post, but how did the Rad Valve work out for your bike? I have a 18 TC250 and am trying to decide between that and the Vforce 4R. Thanks.
Anyway, he decided to buy a Boyesen rad valve & honesty he never touched the reed petals again & had no more problems. The bike ran better also.
On a different note, anyone have an idea why the bike would break so many reed petals with the v-force?
Post a reply to: 2 stroke guys....V-force or Rad valve?
