HD Newbie Question...
After putting it off for 25 years, I just finally bought my first Harley...which is a 97 Road King that has been customized quite a bit and supposedly only has 13,500 original miles on it. With that being said, the guy I bought it from told me it was an 88 ci engine stroked out to 93 ci. I have since learned that it's an 80 ci engine...so I'm assuming it's an 80 ci that has been stroked out to 93 ci.
I ride pretty hard, so I'm wondering if this means that this particular engine might not last me very long considering how much it has been bored out.?.? I've been riding Jap bikes all these years so everything HD is new to me. I'm learning as I go. He's done a lot of work to this bike. It has a 6 speed tranny, Mikuni Carb, new cam, hooker pipes, etc. I was reading somewhere that the more you stroke a motor, the shorter it's going to last you.?.?
I appreciate any input I can get! Thanks.

If you're used to Jap bikes, you need to cut your red line by 50%....

Welcome to our happy place.
You got some bad info, a stroked Evo is 89, 96 and 106, big bores are 85, 88 and 97. A 93 inch is a Shovel stroker engine so you still don't know what you have but overall a Evo is a solid engine but I hate to say it slow in stock form but responds well to modifications.
Until you know what you have in the cases, shift it at 5800 max and enjoy what it gives you.
Even a stroked Evo will hold up and very dependable and know this for a fact but every engine has a out of bounds factor on thrashing it

Welcome to the forum.
If you plan on doing your own maintenance then you really need a Harley factory service manual.
Unless you got the receipts from the build there is no way to really tell what was done to it except to take it apart and see what is in there.
Just to be clear I don't recommend this unless it is broken.
Just ride and enjoy!!!!!!!!!!!

Welcome, the guys here in the Evo section are great, you will get all the answers you need. I can't answer your question, but I will second the service manual. I came from a few metrics and always downloaded the manual. HD has a stronghold on everything, and you probably won't find one, so just go buy it. It's worth it.
Two other pieces of advice. Don't post a dirty picture of your bike here, and don't mention seafoam.
Congrats on the HD!
