i know this has been asked before, but how often or how many hours do you lap/grind your valve on you gx160s. i have heard on here that some of you do it for every race and even between heats and finals.so i spoke to a very good and well known engine tuner, who told me if he services my engines they will not need the vales lapped or valve springs or rings for 12 months or about 50-60 hours. in fact you will prob do more harm than good. unless he has got the hump because i am going to lap the valves myself, this is going to be my routine. 6hrs of sprints coolpower oil/endurance i use castrol magnatec 5-30 12hr lap vales & new g4 springs 12months or 50-60 hours deglaze bore and new rings. your advise please
