STIC Super Torque

Looks like one of the many gizmos that add air to the fuel vapour stream for better atomization. Mostly smoke in mirrors, but it might create a combination that helps some motors.

Just spend the money on gas and ride more.
 
"Note:*due to the intense power created by the use of the STIC Max racing metering block, and Max STIC tube; the engine should be in good working order to withstand the STIC's tremendous increase in horsepower, torque, and acceleration. Due to intense torque increase; it recommended that you consider using a high pressure gear box lubricant such as "Oil Extreme." For your gear box protection, a two-ounce bottle of*Oil Extreme" will be included in each purchase of the STIC metering block that includes the STIC needle jet tube"

. . . Ok forgive me in advance; but only in America can they write such marketing bollocks.;)

The main testimonial is from a chap with a 25yr old carb. Replaced the bit that does all the metering and wears the most. Apparently it went better after. Go figure.
 
There are only a handful of riders who use the full power of a modern 250/300 and most of them just jet the bike properly. The rest of us can live with a burble here and there so long as it is while we are out riding

I did a three day ride from sea level to 2000+m and didn’t change the jetting- it was only slightly fat on the third day but I was tired by then lol
 
I did install one of these STIC metering blocks in my big bore 327 and it is honestly the best change I have made to my GG in a very long time and IMO well worth the money. This is the post with more details on Thumpertalk.

I purchased my STIC metering block from HPR http://www.hpracedevelopment.com/ I assume the two companies are related as the dyno sheet for on the STIC SuperTorque site says HP Racie Develoment.
 
"The engine should be in good working order to withstand the STIC's tremendous increase in horsepower, torque, and acceleration."

Come on...if it really boosted power so much then surely all the factory team's riders would be using them...unless they're too frightened that their engines might not take the stress or the extra power might frighten their riders. :rolleyes:

Save your money and concentrate on getting your carb setup.
 
I honestly should have started a new link in the carb section. This site has more links and videos. http://www.hpracedevelopment.com/stic-metering-block.html

That being said the STIC metering block does work! I attribute this to two issues. 1) I think it does a much better job of fuel atomization which allows the engine to more easily ignite and burn the fuel charge over a wider range of air fuel ratio. 2)Many older PWK carbs have worn needle jets which are not replaceable on the PWK. The needle jet is the metering orifice the tapered needle moves inside of and eventually wears over time.

I know how to jet a carb and I can honestly say this STIC made a noticeable difference across the board on my bike. Check out the Thumpertalk link and other STIC inks.

We are alive and well We invented the STIC metering Block for the Keihin PWK 38mm screw top (90mm) and the shorty (75mm). We are presently the carburetor of choice for the Jared Leshner YZ 250 that qualified for the final against the factory 450 four strokes. the first 250 two-strokes to do that in the last 16 years, the YZ 250 is presently producing +55 hp at the rear wheel, and it is running down the 450s. We have new products coming out this year. contact us at vortex@sticfuel.us. Contact me and I will respond to everyone.
 
New webpage

We are developing a new website and for the present time our Go Daddy information can be obtained by going onto the following sites, just click on either site below.

We are starting to now expand our modifications field by doing what we have been doing to other types of carburetors wherein you can send various types of carburetors to us for four and two strokes engines, including Holley late model carburetors for dirt, asphalt, drag racing, and all other types, mud, etc.

I have been doing the Holley?s, Weber?s, etc., for over 40-years years with great results. The Holley modification typically produces 30 to 40 horsepower gains, and the modification is undetectable.

The New STIC Carburetor is planned to arrive on June 25, 2023.

Pre-orders for the new STIC carburetor are being accepted. Great news, pre-existing Keihin A/S carburetors with STIC or with the stock metering block can be upgraded to the new STIC specs with the air correction jets installed. The new modification price is $390, with a new modified STIC block, with everything including the new Yellow needle. The complete new STIC carburetor is $685 with all accessories.

The original STIC block has been upgraded to incorporate into the new STIC carburetor as well as into the prior art Keihin. This STIC patent drawing is universal, portraying the embodiment of a carburetor and fuel injection body. We have thoroughly evaluated this product under field and dyno testing. We have evaluated these products in varying temperatures, ranging from minus - 30 to plus + 110 degrees, and in altitude conditions ranging from sea level to fourteen thousand feet above sea level.

In the development phase, we modified and evaluated various types of carburetors, including Dellorto, Keihin, Weber, Holley, Mikuni, Rochester, and hundreds of other types worldwide. Even when the structure did not permit, we modified the carburetors and installed various passages and air jets. Most of the fuel systems were made of modified workings that you see in the drawings. I was able to modify the stock carburetors to insert and evaluate portions of the STIC systems.

The new STIC carburetor will have everything that has been thoroughly tested in the field and has been dyno tested showing 10 to 25 hp gains.
In the past, I have implemented this complete modification on the Mikuni round slides and TMX, as well as others. They are so good, they have been outlawed as STIC-modified carburetors, and will not be legal until I can offer them to others to make it fair to the competition. Over various brief appearances of the concept, (1) the STIC was undefeated in the Snowmobile Formula I twin trackers World Championship events, it won every race taking 1st and 2nd places. (2): In the Champ 440 class it won the World Championship, (3): in the Champ 340 class, it won the World Championship. (4): In the World Championship ice drags it won the 800 and 1000 Pro stock classes. (5) It also has several World speed records.



For the very first time, since the new STIC concept carburetor will now become a reality. Recently, we machined the STIC metering block to accept a smaller washer under the main jet, this allows for better fitment, sealing, and crimping of the new brass washer to facilitate the New STIC Carburetor with a planned arrival of June 25, 2023.

The STIC Metering block altitude compensates by more effectively utilizing the available oxygen. The atmospheric air coming into the tube has no escape other than to be entrained (thoroughly mixed with the fuel).
