I am sure most of you have known this for quite some time but I just realized that the factory exhaust valve return spring is stiffer than the ones the factory installed for the intakes
Makes sense (maybe) with the 2012 motor because the exhaust valve weighed more than the Ti intake but I checked the part numbers and neither the SL motors or the 2015 on R motors got a lighter spring
Do any of you know why?
Has anyone tried using 4 intake springs when running Ti exhaust valves?
With the closing lobe and rocker doing all but the last few thou of work I do not understand this at all. Ti exhaust spring should be even lighter than that used on the intake cuz it’s a lighter valve
Anyone know if the WSBK motors got different springs? At least of the exhaust side?
