What is the average time required to rebuild the topend of a Yamaha xs1b? I will be doing everything necessary to bring it back to like new condition. I know the time can vary widely depending on a ton of variables. Maybe I should have just asked, how big of a job is it? Thanks

Top end rebuild

Jim did a first class write up on an XS top end rebuild. Have a read it will give you an idea. No many changes between models.

You have all the things you need?? And you’ve done it before, pull the motor after breakfast and have it back in before dinner.
Realistically, a weekend should do it, even if it’s a first time, granted the top end just needs a hone and some rings (that you have) but you won’t know until you pull it apart.
If you gotta order parts once you get it apart/ or need machine work for new pistons it could be a month or so of down time. Relatively the same amount of physical work though. Just wait time increases.

I feel there is a difference in the Enthusiast way to do it and a shop repair.
If the engine is out -- there are other updates /Service performed
That depends on future plan and history
And what shop and tools you have .
Frame perhaps cleaned and get some paint
Carburetors serviced ? polished
Parts inspected and measured .New cam bearings .. Measurements... Cylinder bore perhaps .. New
CAM chain ?? Guides ? Springs ?
Con rod small end play evaluated.
Always more than what gave cause for the job and engine out.
Thinking it over perhaps take parts to someone else for a second opinion.
From this viewpoint it is more or less impossible to say before.
Assembling I work slowly trying to get it right the first time and not damaging anything.
As Mr WideAWAKE -- but you won’t know until you pull it apart.
