okay i got a good digital scale and checked mine out and they were 54.6 and 2 were 54.7 so i took off some at the tip and all are 53.6 but i lost some engagement i want to get it back up some it revs to 6500rpm now with a blk/org dalton and 5 .30thou shims i need to get it up 500rpm more i need more engagement or to do the flat spot trick if ya know what i mean what do you think? grind some off by the pivot hole? thanx ohya i think i will take them down to 53 grams

 

well lets start by finding out what exactly u want to do here. do u jsut want more engagement? how much? high? low? let us know how u want it to act and we can help. if u jsut want more engagement then tkae your clutch cover off and spring out and take a magic marker and mark right where the roller touches the weight and put them all on a bolt and set them in a vice to get the even then tighten it up nice and snug so theres no movement. then take a belt sander and grind a dip into the weights right where the roller touches it. dont go to deep at first. itll take some trial and error. i just did my new S55s on my TB this weekend and it make a huge difference. if u need any help just ask. scott

 

grinding below the pivot hole, or tucking as its called, should be done with care. you can trim a couple thousandths too much and you'll have problems. imo, i would grind the top to change your engagement or use diferent weight altogether.
