Ok so i adjusted valves last weekend, motor cold .006 intake .008 exhaust. went for a ride yesterday and when the motor gets up to operating temp there is a distinct valve tap. took it home checked them again intake .006 exhaust i couldn't get a accurate measure. it seems that i put the feeler in from the front it slides right in but is hard to pull out, from side to side slides in and out but was way out of spec. is this Normal? if not what is the correct way to check ? put the feeler in from the side, not head on?? oh and its got a proflo intake thats it..
