Vforce
« on: November 29, 2008, 11:50:54 AM »
Okay... I have searched and read..... I have heard both..
http://www.kxriders.com/forums/index.php/topic,2708.0.html

Vforce 2 vs Vforce 3....   obviously the 3 is for the 250's.... is there a phisical size differance to where its going to unstuff the crank case per say..


If somone out there has PHYSICAL MEASUREMENTS.. that would be nice.... Im about to buy some reeds, and dont want the "unstuffing" affect the 3's may pose. As I hear they are narrower (width) than the delta 2's....  Straight off the bat (look at the links)  I can see what I think is the restrictor plate everyone referes to...


here are the 3's..

the kx250 v-3 work great with stock size carb.   The v-3 for the jetski was made for bigger 44-48mm carbs.

the r&d cage looks nice but the v-2 is a little better.  if you have a dyno at your hands then dyno your combo with all the different cages.
The V-3 is longer so your covering up your boyensen ports.

Why don't you just call Moto Tassinari?  They released the V3 for the CR500 this year with plans to improve it further still this coming year.  I've spoken to them once, as have a couple other riders I'm aware of.  They're friendly and happy to get a tech rep on the phone to answer questions.  The V3 for the CR was improved upon in every conceivable way.  Guys have ran them back to back with the V2 and approve of the new design.

Give them a call Motorrad...no reason to guess and speculate when you can get the straight answer from the horses mouth  :wink:

I will give them a call tomarrow.... since they arnt open today...

Just somthing interesting I found though digging in my Dennis Kirk book..

the part number for the Delta 2  for the kx250 and the Kx500 are the SAME part number.....    that being the case... I dont see why they would change the physical size of it for the delta 3  250 application and reduce volume...

There are several people on here that run the delta 3's.... hoping someone would chime in on how it fits volume wise

Could someone tell me how thick the mating surface of the Vforce reed block is compared to the stock reed block?  I am running the stock reed block with the reed spacer and its a tight fit.  Is anyone running the Vforce and reed spacer combo?  What the fit like?

Found another old post on the reed valve topic...

http://www.kxriders.com/forums/index.php/topic,1100.0.html

Stewart- I know you said that you know the V2s work, but have you by any chance ever ran or dyno'd a RAD? I still have stock reeds and the ol V2 vs RAD on the K5 mystery still seems unsolved unless I missed something in the past.

rad valve stands   for  ,,,release at dumpster  ,,   v2  stands for  ,,,victory  2owner,,,  every reed block that i have tried  with every set of reed pedal  setup   nothing has given me the great results as  the v2s ,,,, i  think i have worn  out  the intake bolts trying diffrent reeds ,, my buddy helping me and the key pad  saying....  stick with v2s,,,,i  think the v2 reeds   larger tip surface  area is what makes it hard to beat,,,  i  tried  reeds  every way and design  came to 1 conclusion  the v2 was the standard  i  could not make  close to the same power with any thing else ,,  they are a real  advantage,,,they are not a gimmick

 Thats a good one. Especially since I just removed my Rad Valve and can't sell it to anyone. I am sold on V-force from what you have stated previously. Lots of different reeds out there, but its important to notice new products and newly developed ones. V-force is an innovator. There's no Rad-valve II or III that I know of. A buddy used a 12-petal mossbarger reed cage for years, only to later see that the cage stuck all the way into tranfer ports and almost completely blocked off both of the vertical ports. He still has the paperwork with all of the power increases that they were supposed to deliver.
  When installing my new v-force, I noticed a problem with pointing the "V-Force" logo up. It ran into the intake or somethin' and had to point the logo down. Is that what happened to yours? Is there a better way to cut those tabs to ensure a flat mating surface? That seemed crazy hackin' on a part that I'm ready to re-install.
