DPS Technical, Inc. & Jackson Racing
DPS Technical, Inc. will be coordinating technical inspections for the Ontario, CA Endurocross event.
As part of our involvement with Endurocross we will host a Southern California refresher activity of sound measurement and have a motorcycle, racecar, sound testing display and a social activity in the pit area.
On Friday October 17, a special environmental panel discussion will take place, hosted by the American Motorcyclist Association (AMA). The topic will be Understanding and Controlling Vehicle Sound in the Environment.
On Saturday, October 18 Chris will be helping motorcycle riders by performing sound testing for motorcycles using an internationally recognized SAE sound testing method and providing noise control guidance to motorsports facilities and regulatory authorities.
For many years DPS Technical, Inc. has been your resource for vehicle noise control education pertaining to vehicle sound and spark arresters.
It is our goal to answer your questions and to help you understand some of the evolutionary changes that are occurring within the motorcycle, automotive, specialty vehicle and Off Highway vehicle industry.
In the event you are an Off Highway vehicle land manager many of these changes will be something that you will be contending with.
In the near future we will be finalizing our 2014 National field training and event schedule.
Please know that our early in the year eastern schedule is somewhat dependent upon the weather, however our Western schedule will include activities at several motorsports events.
Guests are welcome to attend these functions to get experience with vehicle sound measurement and to finalize training or to participate in our continuing education or advanced sound training and certificate programs.
If you have the desire to attend, please contact us in advance for details. Our schedule often has adjustments.

Environmental Outreach Summary 2009-2013
Billabong Pro –Teahupoo, Tahiti
Tahiti Surfing Contest – Environmental Activity Summary
Each year Chris Real from DPS Technical in conjunction with the event management staff performs an environmentally responsible activity during the Association of Surfing Professionals (ASP) Billlabong Pro & Von Zipper Trials in Teahupoo, Tahiti. This helps the community and we enjoy being the “good guys”.
Community Action Overview
In 2009 & 2010 we did a general area clean up and collected used oil / paint and recyclable materials at the various places to prevent hydrocarbon contamination of the lagoon. (Hydrocarbons are linked to cancer and sea life damage, additionally they are a fire safety concern.)
In 2011 & 2012 with the help of Jimmy Mawrr and Paul Scott we completed redirecting and balancing the electrical power lines in the webcast and other buildings, thus minimizing fire risk and overall power consumption. (The attention to detail has prevented some power black outs and lowered the electrocution risk.)
In 2011 an extreme swell hit during the contest.
The “Code Red” conditions resulted in many of the waterfront areas being flooded.
We take pride in knowing that our proactive cleanup activities were directly responsible for minimizing pollution, as many of the environmentally hazardous materials had been removed.
We were able to take in excess of 2,000 pounds of lead and used batteries to the recycling point at the marina.
Our actions have kept a known toxin from contaminating the food chain. (Lead is linked to reproductive harm in humans and is damaging to the food chain.)
For 2013 we placed aluminum and plastic “can crushers” and beverage container recycling points around Teahupoo. The container crushers minimized the physical bulk of the beverage containers and also made it easier for recycling collection. When the containers are crushed they take up less area in landfills and do not float, this is a benefit.
What is in the future?

As the manager of American Honda’s Amateur Motocross trackside support program and a owner / team manager of an Endurocross development team I thought I would share this tip on spark plugs.
First, we all know that the spark plug is an important part of any engine. Without it the bike just won’t run. With an improper gap the bike runs poorly and with a broken electrode a big repair is often needed.
Changing a spark plug in most of the new racing motorcycles requires that the tank be removed and the new spark plugs are $20 so many people just don’t change them very often.
At the Amateur Motocross race level it is not uncommon for us to work on 100 motorcycles at an amateur motocross national. Many of the riders use racing gasoline that is OXYGENATED and it burns hot, or their bike runs lean and occasionally “pings” or detonates. This shortens the spark plug life and very often when we ask the person how long the plug has been in the bike people often say about a season or 1-2 years!
When we remove the spark plug we always just loosen it with the plug wrench and use a rubber hose to unthread it. This keeps you from side loading the spark plug’s threads (and risks breaking a plug off in the head) and also prevents hurting the threads if carbon is built up on bottom threads. Some plug wrench sockets have a small rubber bushing in them, however I prefer to use a hose.
If carbon is built up or the plug is tight we use a multi-purpose lubricant such as Honda Pro or WD-40 to soften the carbon. When we get to about the end of the threads we blow the dirt out of the hole with compressed air to keep the dirt from going into the cylinder.
On installation of the new plug we use an engine assembly lube (Such as Torco cam lube) on the threads to prevent binding. This also minimizes carbon deposits that contribute to worn threads if you remove the plug very often.
We use the rubber hose to lower the new plug in as dropping the plug into the head can damage the electrode and change the gap. The rubber hose also is a lot faster and safer.
We use extreme caution when using the plug wrench when un threading small diameter long reach spark plugs as side loading on the threads can result in a broken plug. If the plug is side loaded and gets broken you need to go fish, and you MUST get all of the parts of the plug out of the engine!
We have a special method of removing broken bolts and spark plugs from an engine. We use a 6-Point T bit and spray lube. Select the correct size of bit, (for bolts you need to drill a small hole) gently tap the extractor in awhile applying un threading twisting motion and pray. We often slightly taper the end of the extraction bit and always use a new bit for this process.
Please be nice to your spark plug. He lives in a blast furnace, is under pressure and gets hit on the electrode 12,000 times a minute for many hours, and once in a while he needs a bit of care.
See you at the races!
