Is the EVO engine good for Harley Davidson?
As others have said the EVO engine was very durable…it was the “revival” of H-D as a company using the funds from AMF.
Are there any issues with the EVO engine?
Only real issue with TC are the early cam chain tensioners. They just need to be checked every 10-20K miles (many bikes want valve adjustments at lower mileages). Later ones (’07 up) are better. TCs do have crank problems when ya start building them over 100hp but few EVOs ever came near 100hp. EVOs had just as many camcase problems as TCs.
Why was the EVO made with a twin cam engine?
The Twin Cam was designed to make factory assembly easier (and of course cheaper) at the cost of most of it being disposable rather than rebuildable. And then there is that heat issue. So if the only thing gained was power, the TC is a total fail. The EVO had plenty for what it went into. A cruiser.
Where can I get parts for my EVO engine?
For now go to Bandit.com and follow their directions to register your EVO for their parts book. This will get you into looking at copies of Harley parts books for your year. Go to engine and oil pump and you will find the tappet screen and where it is. It will also show you how it goes back together.

How did I rebuild my 1997 Evo Top End?
Everything went well with the strip down, took the heads to the engine shop to get them to fit the new guide seals. For the rebuild I bought a complete cometic gasket kit and replaced all gaskets and seals from the cylinder base up. Rebuild went well, head torqued to cometic guidence and everything else torqued according to the service manual.
Are there any problems with the EVO engine?
The Evo’s don’t have heat problems, don’t have chains or belts in the timing chest that can do really bad things internally, don’t have problems with the crank, or the main bearings, don’t have problems with the comp sprocket, etc, etc. Can you tell which one I prefer? Re-reading your post I see that your scoot has only done 32k miles.
How did the Harley Davidson Evolution V-twin engine work?
The relative motion of cylinders was accepted as a given of V-twin operation, so the Evo engine’s intake Y-manifold was made to slip into flexible rubber couplings on the cylinders. Pratt & Whitney had to make flexible intake connections on it 28-cylinder R-4360 radial, after prototypes tore their intake connections to pieces.
