What type of oil are you running in it?
May need to go thicker

mine is a sewing machine too and they say thats normal. an actual knock is probably a collapsed or worn lifter. evo sporty motors are apparently self adjusting, though i havent had one apart before. a friend did cams on his and i was looking at it, the pushrods were adjustable but he said they are just a simple in/out to get them in, and are not used to adjust valve lash...... hydraulic lifters=self adjusting. however, if your bike sat a long time, one might have lost its prime and collapsed
