i currently run on my 250r swinger a 250 carrier, x-33 axle, durablue sprocket hub. then use a 450 blingstar rotor guard with the built in brake stay, 450 caliper, 450 brake hub and rotor,and oem 450 axle nut. here is my question. i am going to start a new (to me)lsr chassis crf450 powered build. with the mixture of rear end parts i have now u need washers to run the 450 caliper and cannot use any anti fade nut. this is why i am running the oem 450 nut currently on my 250. what i want to achieve is to run all 450 rear end, carrier, axle, sprocket hub, brake caliper, rotor, hub, anti fade. it will all be on my lsr no link swinger. what i feel may be the only problem is the chain not lining up properly. may be other problems i don't foresee but this one is most of my concern. what i hope to find is someone has already done this and can let me know that either it will or will not work.
