PC 2000 POWER CYLINDER
Established in 2000 as the top off line Power Valve cylinder for the ’85-’89 Honda TRX/ATC 250R engine. The PC 2000 is the original Power Valve cylinder, and has easily out distanced its competitors by consistently winning races in every major race series in the country.


PC 2000 Features:

1. Cylinder is cast and CNC machined in the USA

2. Duncan Racing preports PC 2000 cylinders in house, before being nikasil coated.

3. Unique port tunnel design offers latest 2-stroke performance technology. With unmatched fuel scavenging. Exhaust port is a 3-port design. (1-main, 2-secondary)

4. PC 2000 cylinder is designed to use a special Power Valve system that helps give the engine an extremely broad and smooth power band for a 2-stroke.

The valve operates on exhaust gas pressure and performs 2-main functions during operation.

A) The up and down movement of the valve alters the exhaust port timing give the engine better low RPM (valve closed) power while still maintaining excellent mid and high RPM (valve open) power. The power curve transition throughout the RPM range offers unmatched smoothness and reliability.

B) As the power valve opens and closes the compression is automatically adjusted. The higher the compression (valve closed/for better low RPM torque) As valve opens compression decreases slightly allowing engine to Rev through the RPM range more smoothly

5. PC 2000 cylinders are available in (4) displacement options;

265cc AMA legal for GNC/GNCC

275cc Best combo of performance and reliability

305cc Increased power over 275cc, but better reliability than 340cc

340cc Largest Nikasil version available

305cc and 340cc versions require center case machining, for cylinder skirt clearance.

The above listed displacement sizes are true calculations. Not inflated in accurate numbers, like other companies list.

6. All PC 2000 cylinders are offered with the highest quality cylinder bore coating by Peoton MaxPower. Coatings offer many advantages over old fashioned steel sleeve liners; decreased cylinder wear, enhanced heat dissipation, less piston/cylinder friction, increased horsepower.

7. The PC 2000 offers over 50% more cooling capacity than stock cylinders.

8. Each cylinder is supplied with it’s own CNC machined head from billed aluminum. Each PC 2000 head is unique to the PC design and offers maximum cooling, proper spark plug angle, inter-changeable and adjustable size domes, O-Ring seal (cylinder and head surface)

9. Rear water fitting is billet aluminum (no cast) and bolts into cylinder with o-ring seal.

10. Multiple Power Curves MIDRANGE and HIGH REV. Because riding conditions variety to many extremes all PC 2000 cylinder kits are available 2 separate port design options.

A) MIDRANGE: for MX, Trails, XC, Desert, Dune Riding, Small TT’s & Ovals

B) HIGH REV: for Drag Racing, Large TT’s Ovals, Hill Racing, Asphalt Drags.
