CNC machined hard aluminium replacements for discontinued items!
These KIPS valves are the race kit version for the outside two valves and have been made to allow another level of tuning. They are CNC machined from 7075 T6 billet aluminium Hard anodised rather than the original cast items.
These valves are sold as a pair as they are handed and you require a pair for the outside only. The centre valves are standard C2 / C3 valves which are available individually. The advantage of the F3 valves is that they allow more flow through, but at the expense of valve strength. Not having had these on a bike for any period of time it is impossible to ascertain if this will seriously affect the longevity of the part, but they are made from hard ally of the same sort drive sprockets are made. As yet we have not had the time to do back-to-back tests between these and standard valves so no dyno figures yet, but that will come
