Empire Industries

Sorry I tried to upload the original pic but it said the file was too big so I had to resize it. As for the inframes we have no plans to build any at this time.

Empire Industries is Owned by Eric Friend who founded White Knuckle Racing in Oregon in 1995.After developing numerous performance parts for the ATV/UTV market and building some of the fastest ATV's in the nation, Eric sold White Knuckle Racing in 2011 and has opened Empire Industries in Riverside California. Empire Industries has no current affiliation with White Knuckle Racing Empire Industries continues to develop new performance products for the ATV/UTV market as well as build high performance 2 and 4 stroke motors. Our passion for performance goes into every motor and it shows! Feel free to call or email us for information on your next build! 951 734 7433 email: Empireindustries01@gmail.com

Here is one sent to me by a customer on his DM

30mm CPW carbs work really well. Great response off bottom and will out flow stock carbs. Anything bigger will lose bottom end performance.

Empire Industries is proud to announce our Banshee Hand coned big bore drag pipes These will work on anything from a 4mm DM up to a 24mm. These will also work on the Twister Cylinders. We have seen 8- 10 HP above some of the stamped pipes on the market. Dyno results will vary depending on your specific build, port heights, compression ratio etc. Pipes are $850. We are working on a hand coned small bore pipe that we will be testing in a few weeks.

Here's a pic of them mounted

I don't plan on making these an in frame pipe at the moment. Just going to concentrate on good old out of frame drag pipes!

Ride.Race.Love......You say that like it's a bad thing! Keep in mind the LED pipes that everyone was raving about, was my design! I did all the testing and all of the dyno research! SO yes while I owned White Knuckle I did a lot of testing and built many fast motors and designed a lot of products for the industry. Definitely nothing to be ashamed of !!!!! These pipes are much like the original WK pipes with a few changes @ about half the price of LED's. Dyno results will vary depending on the motor and within that, Will also depend on Port heights, compression ratio, intake and exhaust port size as well as carb size. I will post dyno results as I test on different motors!

Our New Big Bore Drag Pipes for Cheetah DM and Twister Motors. Custom Hand Coned pipes $850 These look amazing! We are running about 7 to 10 days on building pipes at the moment. Feel free to give me a call at the shop! 951 734 7433

Here is a sneak peak with no stingers. We will be building only out of frame pipes. Will post some dyno charts once we get our dyno set up in the next month.

Already have them on my 10DM. Won't have a chance to do any dyno testing until after this weekend. Heading to Pismo beach to do a little racing.

Sandking ,we will have our dyno set up at our new location by the end of July

I will try n get some dyno charts up over the next 2 weeks. When I had them on a 16mm DM a couple years ago they picked up over 12HP over a set of 41mm Mikuni. People are spending $1600 on pipes for 4 HP I would think they would spend $1100 for 12 HP !

$550 per carb.

Empire Industries is Bringin Sexy Back. We are bringing back our Billet 44,46 and 48mm Cyclone Carbs. These carbs are currently set up for alcohol with dual inlets for use on spread bore motors or single inlets for use on standard spread motors. These accept mikuni needles and jets. Removable emulsion tube for better tuning capabilities. T style flat slide design with dual power jets make explosive power. They are sexier and lighter than before. We are working on our 4 stroke and gas applications. I will keep you informed as things progress.

Sorry for the confusion. I sold White Knuckle Racing in Oregon a couple years ago and moved to Riverside Ca. White Knuckle Is still Open in Salem Oregon ran by Mike Brandes.I went to work for Dasa racing for a little over a year when I moved to California. I Recently went back into business for myself ( Empire Industries) here in Riverside Ca. After 16 years of owning your own business it's hard to work for someone else! lol

Thanks, Eric

+12 Ladder bar swingarm with set up for stock shock linkage. Used 2 wknds. In great condition $485 I have billet axle carrier and caliper mount plate. 40mm or 35mm carrier for an extra $169

$175 shipped to 92503 on 68.5 stock cylinders?

With carrier ?

Drill Main jet and emulsion tube to .118 Use 6FJ41 needle in 4th clip position. 35 to 45 pilot . Start big n work ur way down. Probably end up around 35 to get it crisp off the bottom. Power jets should be drilled to .092 . When making a pass ,start with the power jets wide open. After making a pass reach down and feel the side of the cylinder . It should be warm enough that you can put your hand on the cylinder for 3-4 seconds before pulling your hand off .It should not be as hot as a gas bike. If you can leave your hand on the cylinder longer than 4-5 seconds it's rich . Turn the power jets in 1/2 turn at a time until it builds some heat. Hope this helps
