Under Budget | Illusion's 27-Tooth Motor Sprocket

09. The compensating sprocket, primary chain, and clutch hub were then removed.

10. Here is the stock 25-tooth compensating sprocket (left) and the Illusion 27-tooth sprocket (right).

11. With all the parts removed, Steven cleaned all the gasket surfaces and inspected the shafts and chain tensioner for wear. Using the Illusion sprocket and chain and stock clutch hub, he slid the assembly back into position.

12. He then added a couple of drops of red thread locker to the sprocket nut and torqued it to 150 lb-ft. This time the screwdriver and rag were wedged into the lower strand of the sprocket.

13. Moving to the clutch hub, Steven applied red thread locker and torqued the mainshaft nut to 75 lb-ft. He then replaced the release plate, retaining ring, and jam nut. The word "OUT" stamped on the release plate should face outward.

14. Steven adjusted the cold primary chain to 5/8 inch deflection on the top and tightened the tensioner nut.

15. Next, Steven installed the primary gasket on the two outside pins (one shown by red arrow) and applied the two inspection bolt gaskets to the standoffs inside the primary (yellow arrows).

16. Steven then installed the primary cover and tightened all the outer bolts according to spec, and then added the required amount of H-D SNY3 synthetic lubricant followed by the inspection cover and clutch cover.

17. On a testride, Steven took this photo of his speedometer/tachometer as he cruised near 65 mph and 2,700 rpm. That's a 5-mph improvement over the 60 mph he was getting at 2,700 rpm.
