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.

 

Welcome to the EVO forum!

Expect a welcome package containing a cake and a bottle of SeaFoam from Traildog.

 

I guess that all depends on you definition of 'riding hard'. Any stroker, properly set up, will last as long as you make it last. Run it up and hold it past 6500 rpms and it won't last as long.

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!!!!!!!!!!!

 

LOL!!!! I never got one of those when I joined WTH.

 

Well, since he got Scarlett back together, maybe he'll catch up on getting those out...

 

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!

 

You'll have to SHARE........




Oh, yea, in case you like a CLEAN ride........

 

Welcome! I second the service manual suggestion. Bought my first Harley last summer ('96 Road King) and felt like a complete idiot even after 40+ years of riding, racing and building all sorts of bikes...Japanese, Ducati, Norton mostly. The Evos are real simple once you know what's what. And the guys on here are full of...............great information if you get stuck.

Just ride it and enjoy it. See you out there.
