Exhaust valve for 2T (Power Valve) - full power and wide characteristics

( number of products: 11 )
Filtering

The 2T exhaust valve (power valve) regulates the height and effective area of ​​the exhaust window, thanks to which the two-stroke engine has moment from the bottom and at the same time does not lose power at the top. In off-roading, this is a critical element - a dirty or worn valve causes "sludge" from below, a gap in power delivery and irregular operation. At Bajamoto you will find parts and kits for2T exhaust valves (PV/YPVS/KIPS/RAVE) suitable for KTM EXC/SX 125–300, Husqvarna TE/TC 125–300, GasGas EC/MC 125–300, Yamaha YZ 125/250 (YPVS), Kawasaki KX/KDX (KIPS), Beta RR 2T, Sherco SE/SC 2T and others.

Symptoms of worn or dirty power valve

  • loss of torque at low/medium speeds ("no bottom end"),
  • unequal characteristics - sudden "kick" or a clear "hole" in the middle range,
  • rattling/jamming of the mechanism, audible especially at slow speeds,
  • increase in fuel consumption and "smoking" despite the correct mixture,
  • fresh carbon deposits after a short mileage, oil leaks around the valve cover.

What will you find in this category?

  • blades/gates (guillotine), valve segments and "wings",
  • axles, levers, pushers, cams, rollers and steering wheels
  • bushings/browns, bearings, adjustment springs and wedges
  • servomotors and cables (electric/cable systems – YPVS etc.),
  • covers, seals, o-rings and mounting screws
  • 2T exhaust valve repair kits – complete regeneration set.

The most important features and materials

  • precision machining and hard anodizing/hardened working surfaces,
  • resistance to high temperature and exhaust corrosion,
  • low-friction sliding sleeves and axles - less tendency to "scuff",
  • seals resistant to 2T oil and contamination,
  • OEM compatibility – plug & play installation without adaptations.

Service and adjustment – practical tips

  • Cleaning carbon deposits every 15–30 hours (more often after mud) – the valve should move without resistance.
  • Replace bushings/alignment when you notice any side play or "binding".
  • For cable/servo systems (e.g. YPVS), check the tension of the cables and the position of the setting marks.
  • Always install new cover gaskets and roller O-rings - this will reduce "sweating".
  • After assembly, perform a manual operation test (full opening/closing) and clearance check.

Make sure the valve opens smoothly and you will regain bottom flexibility and linear "draft" throughout the entire range.
