CB1100 forum miles

[kmoney_imp]

Ferret,
Had 90k plus on my ST1100 and it didn't even drink a drop of oil when it left home - my mistake.

My experience with air cooled 4 cylinders, from 35-40 yrs ago, was they needed a bit of rejuvenating around 60-70k miles but I'm sure engineering has advanced tremendously in that time. Heck, everything has.

I've been wondering about this a bit too. My 1981 XJ650 gave up the ghost at 145,000kms. Bottom end bearings still seemed good, as it made good oil pressure and no noises, but it definitely needed at least a re-ring, or likely an overbore, and the head rebuilt as it basically had no compression or power.

I'm somewhat expecting the CB to need this same thing at around the same mileage (yes, I plan to own it that long). Not a massive expense really, if the rest of the bike is still in good shape and I've got that much mileage out of it. I just hope it's possible to get oversize pistons and rings for the CB in 5 or so years.
