Coo, now this was before I set the valves. With the 16/4 I was pulling around 8700, so with the adjustments maybe you could see 9000. As far as the rocker clearance its just enough to touch the supplied feeler guage, still able to pull it out and insert it, but its touching. I'd say it was three times the thickness of the guage before adjustment. On that 16/5 I'm going to trim it to a 15/5 and see. Hasn't been fuel burning weather untill today and I'm useing up this 4 stroke fuel before I purchase the 30%, but will let you know when I do. Joe
