How do I adjust my EVO valve?
Rotate the engine. Watch the intake valve open (pushrod goes up) and then close (pushrod goes down). Continue rotating slowly until the cylinder’s piston reaches top dead center (TDC). The cylinder that you’re adjusting will now have both its tappets on the base circle of their camshaft lobes.

What are the cylinder heads on a 1986 evolution 883?
The cylinder heads you’ll find on 1986-1990 models are: 49.5cc chamber, 1.585″ diameter intake valves, 1.350″ diameter exhaust valves This design provided a squish band over the stock flat top piston, the only year that an Evolution 883 had a squish band. As a result the valves start out closer to the pistons and closer to each other.
What’s the compression ratio on an 883 piston?
However, if you put these heads over a 1200cc conversion and use flat top pistons, your compression ratio will be about 11.5:1, which is really pushing it for pump gas. For this reason, 883 to 1200/1250 conversions usually use a dished “conversion” piston to get a streetable compression ratio.
What’s the difference between an XL883 and 883 head?
The 883 head has a small chamber to match the 3″ bore of the XL883. For 1986, this chamber was a bathtub shape, providing squish bands on both sides. The 883 chamber is also shallower than the 1100/1200 chamber and the valves are longer to match.
When did the Evolution Sportster get a new transmission?
For 1991, the Evolution Sportster got a new 5-speed transmission. HD also made changes to the valvetrain and crankcase breathing that affected the cylinder heads. The cams were relocated to sit directly under the lifters (4 speeds had them slightly offset) and the holes in the head where the pushrods pass through were moved to match.
