SPECIAL 300cc Version of the Cougar Valves - NOT for 250cc bikes -
Pulley set is an OPTIONAL extra - select yes or no below.
Pulley alters timing for standard ignition - pulleys are not required with a programmable valve controller such as Zeeltronic or Ignitech etc.
Version 3 - now re-designed to improve sealing at low and mid-range openings while maintaining excellent top end flow.
Made from very high grade CNC billet aluminium that is renowned for its toughness at extreme high temperatures.
The original and best after-market solution. Beware cheap imitations that are appearing. Material, profiles and coatings may not be the same.
The design incorporates the power-valve 'pin' that is much larger and made as part of the centre blade meaning that it is impossible for the pin to fall into the cylinder, treated with a hard, self lubricating, ultra low friction coating.
Superior life expectancy and operation.
In some of our tests we monitored a 6hp increase with good mid-range stability on a standard motor. Results may vary depending on your
state of tune and condition of current valves & ports etc.
Uses the original spring.
See http://www.rgv250.co.uk/index.html/_/articles/power-valves-r24 for further set up info.
The price here is for a 250cc set of 4 valves, 4 caps and 6 screws.
