Our Ride of the Month for September probably has the toughest existence of any motorized vehicle we can imagine. It spends most of its operation at full throttle and is routinely sent hurtling over 90 foot jumps. It even has to endure the occasional crash. Despite its tough lot in life, this machine receives meticulous care and has been ridden to glory in national competition. Our feature this month is the Biro Racing Kawasaki 112cc Super Mini motocross racer. This unit is as close to a “works” machine as you will find in amateur racing.

Moose Jaw, Saskatchewan’s Biro Racing consists of riders Kyle and Jarret and parents Keith and Tracy. What separates Biro Racing from many other family motocross endeavors is the level of effort and commitment. When the boys’ inherent talent become apparent, Keith and Tracy made a pledge to give them every opportunity to be as successful as possible. Every minutiae of the racing effort, from training to equipment preparation is deliberate with the objective being nothing less than excellence. Kyle and Jarret have even traveled to Texas for the past few winters to train with a world-class coach in an effort to optimize their skills. All of this has paid off with innumerable provincial titles and strong results in national and US races.

For 2012, the boys achieved tremendous success at the Parts Canada TransCan event at Walton Ontario. This is the elite event in Canadian amateur motocross racing. Jarret finished 5th overall in the 65cc (ages 10-11) class and 8th overall in the 85cc (7-11) class. He finished 3rd in the first 85cc race, but some bad luck prevented a higher overall placing. Kyle finished 2nd in the 85cc (12-16) class and 3rd in the Super Mini class.

Kyle’s crowning achievement for this season was his qualification for the Super Mini 1 (12-16) class of the 2012 Loretta Lynn’s Amateur National at Hurricane Mills, Tennessee. This event actually takes place at the ranch of country music star Loretta Lynn and has been the preeminent amateur motocross event since 1982. Virtually every top pro over the past 3 decades has participated in this event during their amateur career. Hundreds of riders attempt to qualify for the National in regional qualifying events held throughout the US. Kyle finished a solid 10th overall at Loretta’s out of 41 finalists. In our opinion, this puts Kyle in “world class” territory for his age.

Biro Racing Kawasaki Super Mini Motocross Racer

This Kawasaki Super Mini is a remarkable specimen. Every aspect that could be improved over stock has been either modified or changed altogether. This unit started life as a stock 2011 Kawasaki KX 100. As the maximum displacement for the “Super Mini” class is 112cc’s, the first order of business was to add a “big bore” cylinder to get the displacement to 109cc’s. Then a “stroker” crank kit was added to reach 112cc’s. But that was just the start. Keith left no stone unturned as he built what is as close to a “works” machine as you can get. Here is the list of mods:

  • Ward MotorSports Engine porting, cylinder modifications and head work.
  • Polished transmission gearing and gear case
  • Hot Rod’s Stroker Crankshaft
  • Wiseco racing piston and main bearings
  • Wiseco Clutch
  • Pro Circuit exhaust pipe with R304 Silencer
  • 100 Octane race fuel
  • Amsoil Dominator Synthetic 2-Cycle Racing Oil
  • Amsoil 10W-40 Synthetic Motorcycle Oil (for transmission, changed every 5 hours)
  • Fluidyne radiator
  • Boyesen water pump
  • V-Force 3 reed valve system
  • Filtron air filter
  • Factory Connection custom suspension with works KYB fork internals, Fox RC2 rear shock, PR2 linkage
  • Pro Wheel hubs
  • Excel Rims and brake rotors
  • Renthal bars
  • Sunline clutch and brake levers
  • Sunline stainless steel arched foot pegs
  • Works Connection holeshot device
  • Tag aluminum front and rear sprockets
  • Renthal R1 racing chain
  • Dunlop Geomax MX51 front and rear tires
  • One Industries decal and number kit

As a good Super Mini will generate around 30 horsepower and weighs only 140 pounds, the power to weight ratio is nothing short of astonishing. This bike would embarrass a good 4-stroke 250cc MX’er in a drag race to the first turn. This unit currently has 104 hours on it. Keith rebuilds the top end every 15 hours and does a full top and bottom-end overhaul every 30 hours. He keeps spare heads, cylinders and cranks on hand and cycles them through his maintenance schedule to eliminate downtime. He sends the suspension back to Factory Connection for a rebuild and re-valve every 40 hours. This attention to detail limits DNF’s and keeps Keith’s wallet from gaining too much weight. As you can imagine, this regimen has him spending many a late night in his garage.

An important service bulletin has been distributed by General Motors pertaining to vehicles manufactured between 2007 and 2009 that are equipped with the “HFV6” engine.

The issue at hand is premature timing chain wear that has resulted from extended oil change intervals under certain driving conditions.

GM’s solution is to recalibrate the vehicle’s oil life monitor so that the owner is prompted to change engine oil on a more frequent basis.

The affected vehicles include:

  • 2009 Buick Enclave
  • 2009 Chevrolet Traverse
  • 2007-2009 Cadillac CTS, SRX, STS
  • 2007 GMC Acadia
  • 2009 GMC Acadia
  • 2007 Saturn Outlook
  • 2009 Saturn Outlook

If you own one of these vehicles equipped with the “HFV6” V6 engine and if you have not received a letter from General Motors, visit a GM  dealership and have them address the “10287C” recall bulletin.

For owners of these vehicles that may be using AMSOIL synthetic motor oil, AMSOIL has published a technical service bulletin on the matter. See TSB: Service Intervals for GM Vehicles with HFV6 Engines.

The upshot of this AMSOIL bulletin is to urge owners of the aforementioned vehicles to have the recall procedure performed and then change their oil when prompted by their oil life monitor. AMSOIL is not promoting extended oil change intervals for these cars, but they do suggest that AMSOIL synthetics are the best defense against premature  timing chain wear.

AMSOIL OE10W-30 Synthetic Diesel Engine OilAs some manufacturers are now suggesting the use of 10W-30 in their diesel engines, AMSOIL has released the API CJ-4 licensed OE 10W-30 Synthetic Diesel Oil. Ford has been recommending 10W-30 for winter operating temperatures in their F-Series diesels for several years now. Caterpillar also advocates this grade for several of their engines.

This 10W-30 joins OE Diesel 15W-40 in the growing OE series. Like the rest of the OE line, OE 10W-30’s drain interval is as suggested by the original equipment manufacturer. OE Diesel oils are a suburb value, considering the outstanding protection they deliver and the low price.

Keep in mind that even though this product meets the latest API CJ-4 specification for 2007 and newer diesel engines, it is certainly “backward compatible” with older diesel engines making this product a great fit in fleet situations.

Below is a “Q and A” article published by which covers the basic questions regarding this product.

1. Question: Why was AMSOIL OE 10W-30 Synthetic Diesel Oil (OEC) added to the OE Diesel product line?

Answer: AMSOIL OE 10W-30 Synthetic Diesel Oil was added to address the needs of model year 2007 and newer heavy- duty diesel engines requiring an API CJ-4 oil in an SAE 30 viscosity grade. The SAE 30 viscosity grade is gaining acceptance in the diesel industry for improved fuel economy and cold weather performance.

2. Question: What are the benefits of using AMSOIL OE 10W-30 Synthetic Diesel Oil?

Answer: AMSOIL OE 10W-30 Synthetic Diesel Oil is a full synthetic API licensed product engineered to perform in older and modern diesel applications, including those equipped with turbochargers, diesel particulate filters (DPFs) and exhaust gas recirculation (EGR) systems. The shear stable, lower viscosity grade provides improved wear protection during cold temperature start-ups and increased fuel economy over SAE 40 weight oils.

3. Question: What is the recommended drain interval for AMSOIL OEC?

Answer: Similar to AMSOIL OE 15W-40 Synthetic Diesel Oil (OED), OEC is recommended for use at the OEM recommended drain interval. Refer to your owner’s manual for specific oil change interval recommendations.

4. Question: Can AMSOIL EaHD Extended Life oil filters be used with AMSOIL OEC?

Answer: Yes, but the oil filter must be replaced at each oil change.

5. Question: What applications can AMSOIL OE 10W-30 Synthetic Diesel Oil be recommended for?

Answer: AMSOIL OEC is recommended for diesel engines and, where appropriate, gasoline engines requiring any of the following specifications:

  • API CJ-4, CI-4+, SN…
  • ACEA E9
  • CAT EFC-3, ECF-2, ECF-1-a
  • Cummins CES 20081
  • MB 228.31
  • MAN 3575
  • Mack EO-O
  • Volvo VDS-4, VDS-3
  • Renault RLD-3
  • MTU Type 2.1

6. Question: What package sizes will OEC be available in?

Answer: AMSOIL OE 10W-30 Synthetic Diesel Oil is available for purchase in:

  • Quarts
  • Gallons
  • 2.5 Gallons
  • 30 Gallon Drum
  • 55 Gallon Drum
  • 275 Gallon Tote Bulk

7. Question: How is AMSOIL OE 10W-30 Synthetic Diesel Oil different from AMSOIL Synthetic SAE 10W-30/SAE 30 Heavy-Duty Motor Oil (ACD)?

Answer: AMSOIL OEC meets API CJ-4 requirements for engines made in 2007 and later. These applications are equipped with modern diesel emission systems including diesel particulate filters (DPF). It is also backward compatible to earlier diesel specifications including API CI-4+. AMSOIL ACD provides outstanding performance in pre-2007 diesel engines but is not recommended for applications requiring an API CJ-4 engine oil.

8. Question: What are some of the target markets for this product?

Answer: AMSOIL OE 10W-30 Synthetic Diesel Oil is designed for owner operators and maintenance professionals currently running OEM drain intervals but desiring the extra protection provided by AMSOIL synthetic lubricants. Markets include heavy-duty trucks, off-road equipment, commercial delivery vehicles, work trucks and sport turbo diesel pickups. It is an excellent alternative to risk averse consumers who want experience the benefits of synthetic lubricants.

9. Question: Why was a 10W-30 developed and not a 5W-30?

Answer: Research revealed that 10W-30 is more widely recognized by OEMs and specified by Ford for newer turbo diesel pickups and by off-road manufacturer Caterpillar for heavy-duty engines. In addition to being API licensed, AMSOIL OE 10W-30 further reduces the barrier to selling into these applications by utilizing a 10W-30 viscosity grade.
