How long will a CB engine last?

[Jurlie_imp]

As long as it keeps running into perpetuity without me having to do anything but change the oil, I'll be happy. I do not plan to crack the valve cover open.

You guys don't check your valves?
I check mine every 24k (twice as many miles than what manual says) and every time at least 4 valves are out of spec.


Question to those with high mileage: don't your transmission whine on an aggressive acceleration? My 1st gear does noticeably, and 2nd is quieter, but still does. I'm wondering, should I order bearings and learn how to rebuild it or it's still fine for another 20-40k?
Current mileage is 63k miles.

Hey Jurlie - Do you have no side-effects with the out-of-spec valve clearances?

Like pops on hard acceleration, harder cold starting, rough idling, and symptoms like that and maybe others?

None of these, as they were not more than 0.02mm out of bounds.

Curious: Did you perform the check+adjustment yourself, or have a trusted service garage perform the procedure? If the latter, how much was the job?

I did it on my own.
My friend recently did the valves on his triumph tiger in the shop, and he paid $1k for it, it that helps.
