wrong connection i think if error r5 in every on of the MC.. about the time it cannot show the time, temp, voltage at the same time youl only choose one of the three in on mode just press and hold the setting button until the time chage to temp the voltage then time agian

Hi, is there anybody here who experienced the SP811 1.85 rear mags is not totally centered? its a little bit on the left side that is why my rear tire is hitting my stock inner fender when I have a backride. My setup is RB Brake kit, RB SP811 Mags 1.6f/1.85r on Stock swingarm and RB Monoshock. All of the spacers of RB brake kit were installed where they should be based on the diagram of @john_carlo . I am thinking that maybe purchasing a RB swingarm will fix my problem but I'm not 100% sure about that. The RB swingarm is a little bit pricey so I have to be 101% sure. Hope you guys can shed to light to my problem.

well maybe your right, will a slightly longer sprocket hub center my mags? maybe i should look for a y125z sprocket hub since my mags is for y125z labeled in the box when i bought it from sir @speedmaniac what do you think? do you have idea how much is the price?

yes paps because if you will alter the spacer in the hub rear spocket will not be allign to the front,, have you tried the rs100 hub.. or my way of resolving the proglem is putting a washer in the collar spacer insde the hub between the mags and the hub thickness is depend on the allignment of the mags then shaving the spacer in the rotor side according to the thickness of washer

not yet tried any other sprocket hub paps, your 2nd option is a little bit dangerous for me though. The space between the rotor bolt and the caliper bracket is already tight it might hit if the shaving is not accurately done. What is the feeling if the rear wheel is not aligned to the front wheel? I already traveled hundreds of KM with my setup but didn't notice anything wrong, its just that it hits my inner fender if i have backride. My temporary solution for now I moved my inner fender to the left side but still not totally free from hitting by the tire.
