This whole problem is due to the SV's slim build.
IL4's get away with a stubbie little leg 'coz the frames are so wide there. With such a long leg the wear is exaggerated.
I did consider welding a block on the foot but it runs close to the chain as it is and I don't want it drooping mid-corner either.
Extra length seems to be the way to go. (Never had a problem in the past.
)
Sorry about the hijack Ricardo!
