SRS Engines Offers 2001 Honda CR125 Power Valve Plugs

Honda CR125 1999 to 2001 cylinder power valve plug

Top performing, precision, investment cast power valve plugs for the 2001 CR125 cylinder are now available from SRS Engines.

The shape of the exhaust duct in the 2001 cylinder is critical to power production. The stock 2001 power valve shape sacrifices peak power to give the engine a broad motocross power band that has good response as low as 6000 rpm. Since stock 125 shifter karts operate above11000 rpm most of the time, they can ignore low rpm power in trade for power gains above 11000 rpm...

Superior Fuel Delivery Unveiled


The All New SRS Engines Hybrid Float-Twin Pump Carb System


SRS Shifter Kart Engines - Hybrid Carb System - Better Fuel Delivery!Testing is complete and the results are exceptional. Relative to the twin pump fuel re-circulating systems traditionally used today in SKUSA stock CR125 shifter karts, the new SRS Engines Hybrid Float-Twin Pump Re-circulating System performs better in every track test and dyno test we ran.


On the dyno the new SRS Hybrid system with the stock Keihin PWM38 carburetor showed a horsepower increase of 0.5 between 11000 and 12000 rpm with no negative side effects through the power range. The increase comes from refined control of the fuel mixture (i.e. the richness or leanness relative to rpm). In the former twin pump systems, the main jet and pilot jet could be used to alter the mixture curve to gain more performance in parts of the rpm range but not all. The SRS Hybrid system utilizes the stock float assembly to limit the fuel level in the float bowl to achieve the optimal fuel mixture throughout the power band.

Your SRS Stock Honda CR125 Is Waiting!

SRS Stock Honda CR125 Engine
Why pay more money for a Stock Honda CR125 package, so you can finish behind an SRS customer?  Whether you're in Vegas or Texas, that just doesn't compute!

 

The SRS Engines Stock Honda CR125 setup was painstakingly dyno developed to locate those hard to find tenths of a horsepower that various tuning combinations can make. When all the SRS increments of power are added together, the result is SuperNationals winning performance for both the SKUSA S4 and S5 classes.

 

Each stock Honda CR125 is serialized and meticulously assembled to insure that critical tuning dimensions are held within tight tolerances. This insures legality and consistent performance. A log is kept for each engine that contains notes of those critical tuning dimensions when the engine is built and each time the engine is serviced at SRS. Each Stock Honda CR125 is built as good as it can be and SRS service keeps it that way.

 

If you want to own the SuperNationals or any other podium like SRS equipped drivers do, call 903-769-4140 now!
