You are correct Puc, I resealed , put in 1.2 Sonic springs with 15W fork oil. I don't recall spacer size at the moment. I did pay attention to pre-load and sag while setting it up. It does ride a little stiffer than stock but not harsh by any means. I find it to be an excellent change, I've never been so confident in the handling of the bike as I am now. Some of this confidence can be attributed to the B.F. Goodrich T/A Radial I now run on the rear and 130 Michelin Commander II up front. I did also grease the neck bearings and swing arm bearings too. Both sets still had factory grease and looked good, repack and go. Next time my money tree is overgrown I'll be upgrading the rear shock.
