I did a three-hour ride on the bike today. Mixed sand wash, rolling jeep trail, modest hill climbs and a few miles of single-track in and out of dry washes.
Throttle response is better all through the powerband. Seems to rev better throughout as well. Just in case I had stumbled on a perfect SSS, I purposely mangled the A/S a few times. Response was still there, except for one spot where the bike felt sluggish all over.
I was able to take the bike on the highway and was able to top out at 75mph (normally 70mph).
Pretty cool.

You're still running a CEK-3? And 1 3/4 out on the air screw?
If you have tried the CEK on -4 and know you don't like it for whatever reason, great! If you have not, you should.
I'm curious about the 1 3/4 part, too. That's not generally where others have found the SSS. Again...if that's where your bike works, great! But until you know (by trying it) that something else DOESN'T work you may be missing something.
IF 1 3/4 is it, then 1 13/16 won't be it..and 1 11/16 won't be it, either.
Maybe 1 3/4 is better than the 3/4 you started with..but maybe it's not the best spot for the air screw.
Most of this based on a post from you around September of this year....
Don't need to keep anybody waiting. With the thumbscrew you can change it on the fly.
Good to hear you like the V-Force3!

Hey all
For you guys that have the VF3, did you have to change jetting any after the install??

No. You do not have to.
You don't have to change from OEM jetting, either.
OK..kind'a kidding.
How about, 'probably not.' It depends on where you start from. Rule of thumb..expect to change something after every modification. At least check it.
I didn't change jetting in my bike from a 2 to a 3. No brass anyway.

Jetting? I made no changes after installation of the VF3. If I were borderline lean prior to the VF3 swap, I might be inclined to do a plug chop.
Anywayz, the improvement is noticeable on the trail -- If you have stock reeds and were choosing between the Boyesen and VF3 system, the VF3 gets my vote.
But if you already have the Boyesen reeds, I wouldn't drop everything and move to VF3.
CC,
I run CEK-3 in the hot months and CEK-4 in the cooler months. I have a DEK but haven't used it yet.
I have to admit that finding the SSS is hit or miss for me. By the time I've warmed up the KDX for our impromptu trail rides, everyone else is sprinting for single track. I have to go with QC's historical advice.
Quail Chaser used the same settings, even for the SSS. Here is a quote from him on a question I asked on anothe forum:

BR8EG plug, CEK #4, 152/40 A/S 1 1/4ish Winter
BR8EG plug, CEK #3, 150/38 A/S 1 3/4ish Summer/High elevation
For me it ran as 1trackn stated..."like a raped ape".
I sure miss the KDX on the kids rides. The KX wants to be run hard. The KDX was happy running easy or hard.

Start at 2 1/2. Bracket that by 1/16th's from there. My 'range' is about 2 5/8 (warm weather) to 2 3/8 (cold weather). Last weekend is the first weekend I've had it below 2 1/2 in so long I don't remember..but it was in the mid-20's when I left the house, too.
It's there. I used to wonder if it was only a 200 thing, but other 220s riders have found it.
Again, it IS picky. Overshoot by 1/16..and you will miss it.
On the money...you'll know it!! It's a BIG deal!

I could'a saved a whole lot of money if mediocre skill was the limit.
But, it's just fun!
Joking, mostly.
Between just a handful of rides I see places or similar spots that I would have had trouble with 'then'. A bike that you have confidence in..that instills confidence because of the way it runs..THAT is the fun part.

Speaking of fun, yesterday after our ride, we went to a local bar and grill that serves we dirtbikers, kwadders, sand-railers, and the Rhino/Ranger set.
One lady (about 43y and willowy) was out riding with her 8-year old son (they were both riding the MX track). She on a YZ 85, he on a spiffy new Honda 70 four-stroker. She wanted to go in to have a drink (Crown Royal and Monster) and she asked me to take the YZ out to escort him around the track in back.
That YZ was fun. Burbling in the low-end but with that spectacular mid-range hit that brings fear to middle-aged YZ 85 riders everywhere.
Needs a torque pipe to smooth it out some (but that's another thread).

Funny. My kid once was whining that his KX 85 couldn't do wheelies , I got on the thing and that little mutha was ripping wheelies with my lard ass on it with just the throttle. something about 143 lbs. and 20 HP that just puts a smile on your face. His new bike is a blast. 30+ Hp , and 193lbs or so. the thing is awesome to ride. The suspension is unbelievable.

Lard what?
Maybe it was a TRACTION issue. Probably a bit less wheelspin with lard on it?

A relative performance guage.
I was trying to figure out a way to gauge my perception of the increase in performance from the Boyesen to the VF3. The 70mph to 75mph top-end increase is very easy to internalize. But there is also a bit quicker throttle response and some low-end improvement.
I decided to repack my silencer after a few weeks of riding, and to clean the air filter. We know that doing both can have a measurable impact on performance, and as expected, they did on yesterday's trail ride (we were marking the trail for a race).
I'd say that for the bottom end, the new reeds are almost, but not quite as performance-enhancing as a repack and filter clean. Call it 75% or so.
Just a guestimate.

Glad you like'em.
It is easy to run out of words to 'splain what things do.
Actually...you didn't say you DID like them.
Enough better? Good enough? Glad you got one? Y-A-W-N? Money better spent on gas?

Money better spent? Going from Boyesens to VF3? I wouldn't recommend it for everyone.
But there were two changes I didn't mention...
One is that it runs down the road at 60+ without *a lot* of that hurky-jerky feeling as if the KIPS valve is on the edge of power-on or power-off. It's still there, just not as bad.
The other thing I forgot to mention is that with the Boyesens, I would get to the RPM range where the Plat II torque pipe would begin strangling the motor. With the Boyesen, it was fairly sudden and noticable - as you've all experienced with a 220. With the VF3s, I'm up against the limitations of that pipe much more solidly. I'm not quite sure, but the bike seems a bit stronger throughout the upper revs including just below where the pipe shuts things down. It's as if the VF3s give me a glimpse of what a different pipe could give me. So, now, it's not just noticeable, it's kind of annoying.
Maybe sometime down the road, today's purchase of the VF3 will lead to (nay, force) a purchase of a rev pipe tomorrow.
