Description Item #VFO0004

The VForce reed valve system by Moto Tassinari has been the reed valve system of choice by anyone serious about two-stroke engine performance for the last 10+ years. The simple premise of the VForce3 reed valve system is to increase engine power and throttle response by increasing the efficiency over a conventional reed valve design.

The unique design of the VForce reed valve system features double the reed tip surface over a conventional reed valve design. This has two major benefits: 1) The reed petals only travel half the distance as a conventional reed valve design to get the same airflow. 2) Because the reed petals only need to travel half the distance of that on a conventional reed valve design, there is a greater chance of them being fully opened as well as a better chance of sealing when they are "closed". A reed petal never truly "closes" in a classic sense, as it is always in movement. Consider this, an engine operating at 8,000 RPM results in a reed petal opening and closing 133 times in one second. This fact sheds light on another VForce advantage. Since the petals are only traveling half the distance, they generally last longer and they receive less wear than the reed petals on a conventional reed valve design.

  • Double the reed tip surface over a conventional reed valve design.
  • Increased bottom end, stronger mid-range and longer top-end.
  • Greater efficiency due to reduced reed petal travel.
  • More airflow means more horsepower.
  • Reduced reed petal wear.
  • Screw-free design eliminates risk of screws going through motor.
  • Screw-free design enables super quick reed petal changes.

Great for my 2015 yz250

Throttle is a lot more responsive, and feels like it has more bottom end power.

Well first the reeds strait out of the box had a big chip in them and then after tearing old power valve out they dont fit in my cr250. Overall they may be great if they were to fit but i returned them and just went to a boysen rad valve.

Increased throttle response and power in minutes!

I have an 04 Yz 125 that was a garage decoration for about 10 years 100% stock original everything low low hours.. Anyways I have to say after torque ing down bolts, new plugs, cleaning a gummed up carb and getting the bike running it just had terrible throttle response no low to mid range control and the high end power band was a slap in the face everytime it's almost too sketchy. After bolting on this reed system (very very easy install) I noticed an immediate crispy throttle and sound, so much smoother I just roll that throttle back and I finally feel like I have total control of this machine, also leaned out my bike which was exactly what it needed to eliminate fouled plugs and splooge. I am 110% satisfied and can't wait to get an exhaust kit and jet kit to really make her rip, thanks Moto Tassinari for helping me build an awesome machine!

Works great but hard to install

The directions state that you might have to cut the rubber tabs off the stock intake manifold. Let's just say it's a lot easier said then done and the stock reeds bolts will not be the correct length to for the new reeds

Put a little extra zip in your 2 stroke

This is my third VForce reed valve and the reason for that is that they work. It woke up my son's YZ125, now it revs from the bottom to way over the top and everything in between which is what his bike needed. Installation was fairly quick once I took my sub frame off and it bolted on easily with the supplied parts. What more can one ask for when the product delivers as advertised. Buy it, you wont be disappointed.

Awesome!

This product does exactly what you buy and some. My throttle response is is amazing and sounds throaty which is also cool. They were easy to install on my 2001 YZ125. The shipping was great like always and like always showed up couple of days early. I can't wait to go riding this weekend!

Not a quick bolt in.........

V Force almost made a reed cage that wasn't worth the trouble.
On my 2002 ktm sx250, you have to cut the reeds off flush on
the stock Boysen block. File, cuss, and fab up a carb adaptor.
Good reeds, for the money, it should be a straight bolt in.

VForce 3 Reed Valve System

Somewhat easy to install. The existing air boot for the KX85 & kx100 will need to be trimmed, which a template plate is provided in the kit. I does mention this in the detailed instructions as a possible task/
Be sure to adjust your jetting, the V Force will make the bike run leaner. I had to increase the main jet from 138 to 142.

Great product and provides additional power throughout the throttle range.

Increased mid range hit

I freshened the top end of my 02 yz 250 and added the v force 3 reed.
I have noticed an increase in my mid range. So far, happy with the installation and performance.

Q: Jetting with these reeds and pro circuit pipe and muffler on cr 85r expert?

I have an 04 Honda Cr85r big wheel with a full pro circuit exhaust system and was wondering if I need to re jet after I put the V Force 3 Reeds on the bike? Help will be greatly appreciated! Thankyou!

A: I would recommend installing the VForce and riding the bike to see how it is running then tuning your carburetor from there if necessary. It really depends on your location (altitude/temperature) and how your bike is running with the current jetting. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike.

Will I have to make any modifications on a 2000 yz125 for this to fit? Also will I have to rejet?
MotoSportExpert

A: No modifications would be needed to fit the VForce 3 Reed Valve System. Normally when installing a VForce 3 Reed Valve System only minor jetting changes are needed, if any at all. If your bike is currently jetted properly you will likely not have to make any changes after installing this VForce. I would recommend installing the VForce and riding the bike to see how it is running then tuning your carburetor from there if necessary.

A: Depending on what bike you have the Shorty silencer generally adds bottom end. The V-Force 3 Reed Valve System design widens peak power and increases the horsepower over the entire range of the power band. Personally a pipe, silencer, VForce and suspension (valving) were always the first things I added when I got a new 2-stroke.
