Parts & Services

Parramatta Racing Engines: complete engine service or parts supply and tuning help.

VHM/EHR products are easy to use, good quality parts that make a difference. HGS and Van Hasselt (VH) pipes are at the top of the ladder, and VHM products are well made. We can supply the parts and help you with fine tuning so you can race at a higher level.

We can send parts overnight, road or air. Payment can be made by Credit Card, Cash, or Cheque. Information is best sent by email, but please call if it’s urgent. Phones get busy, email can be best sometimes.

Jetting changes for climate changes can be obtained if you give us your temp. RH. and elevation. They are minor modifications but are important at national racing level. Figures listed are at 25-30 degrees.

Please call first if you are sending engines. We have preferred transporters with insurance.    CYLINDER PORTING, CARBYS MODS, CRANKSHAFT REBUILDING ARE DONE EACH DAY BY OUR MACHINIST, NO BOOKINGS ARE REQUIRED,  BUT COMPLETE ENGINES TAKE A WHILE AND WE ARE BOOKED ABOUT 2-3 WEEKS AHEAD MOST OF THE YEAR. DYNO TESTING HAS TO BE PREBOOKED.

ENGINE DYNOMETER and BIKE DYNOMETER.        ( THE TRUTH METERS!  )

We have 2 dynos for testing. The bike dyno requires a slick race type tyre to be fitted before testing can be done. The Engine Dyno requires the engine only , to be bolted in place. The engine dyno is more precise and gives a true power reading that can be compared to the manufacturers specifications. We test the 50cc auto clutch type engines only on the engine dyno, as this is much more precise . Dyno test graphs are the property of the engine/bike owner , and cannot be printed or viewed by others. All fitting and testing costs are charged at $99 per hour

We have found the European exhausts make the best power, and the pipe is the most important mod part changed. We dyno test exhausts alot, as well as heads, carbs etc. Alot of testing takes place in Europe in the off season, winter time, november to  january.  Tracks are closed, but engine tuners are busy.

Special hand made exhausts
from Belgium . Van Hasselt.

   * VHM air box intakes  increase the 4 stroke power big time!   Increase the top end power on the two strokes, nice easy mod to fit.
    *    2020 World Junior Championships in Greece,  if you are competing, now is the time to book flights, accomodation etc.
    *Two stroke Exhausts for MX-  the mid range power always  gives the best lap times.
    *Modern two stroke exhausts on small engines, 50,65,85 125  will the silencer length make a big difference to the power?   NO. ( unless we are talking about extreme length, which will cook the engine!   Sorry, if you are thinking a shorter or longer silencer will make you win the race, it wont.  Dyno tests prove this.
    *2020 Best bikes for MX, KTM sx65  sx85 and sx125   Dyno tests tell the truth!
    *Cylinder Porting- the biggest power increase from one item, on the modern 2 strokes in 2020. This should be the first mod  to do for any engine, to gain power!
    * Wilson Todd lands a high paid ride with Kawasaki, MXGP 2020.  Yes he is rich!
    * Australian World Champion rider Caleb Grothues, living in Italy, racing European Championships and supercross 2019-2020.

BELGIUM Van Hasselt Exhausts / 2 stroke (VHE) 65cc to 300cc

The mid range power of the Belgium made exhaust is very strong, specially designed for sand tracks and general mx tracks. After fitting this exhaust its common to change the rear sprocket size 1-2 teeth , as the engine power increases and pulls the faster gearing easy, and produces faster lap times.

Van Hasselt- Belgium Exhausts – 2017 has seen the introduction of these sought after exhausts in Australia finally. The Belgium exhaust low volume hand made producer , makes each pipe exactly the same, and specialises in extra grunt bottom end power, while also still has very good mid and top end. Motocross, Enduro and flat trackers are enjoying this type of power . There is no other pipe we have tested that has this smooth ,quiet , type of performance. We have some stock engines, with just the VH pipes/silencers fitted and jetting changes done, and the riders are winning at top level race meetings, MX and Flat track. The difference, is very noticeable.

 

KTM SX50 2009-2020    NOTE-  rules only allow some changes, depends on the machinery examiner on the day at each race meeting. Engines are never fully stripped, but items like clutches, ignitions, cylinder head, reed valves, carbys are checked. A stock engine can be changed to make more power, without making changes that can be seen!  The exhaust can give a big increase in power!
