I have an 06 m7 I want to get the primary sheeves closer to the belt (.015 - .020) right now there is about a 1/8" I bought the sled used with 200 miles on it about 2 yrs. ago the first owner had alot of work done by Bikeman, anyway heres the problem I removed the spider and no shims only some wierd steped spacer I remove the spacer and I have no belt clearance I dug into the old parts box and found a hand full of engagement shims all differnt thickneses and started to try some combinations hours into this with some added hair loss it is too wide or no clearance it is mind boggling and also it almost looks like the spider has been machined on the back side and without about an 1/8" spacer between the spider and the floating sheeve it will bottom out on the wieghts is this another Bikeman blunder or I'm I missing somthing PLEASE HELP
