There are 5 nuts you must loosen first, 4 on the underside that holds the case to the mounting plate and one attached to the frame. After that you can adjust it. Therz a long bolt that extends from the right rear of the tranny case. A nut is pushed up against the case. Loosen the nut and use a wrench to adjust the chain by turning the bolt. Tighten the nut down once you have the desired tension on the chain. Then you gotta adjust the rear chain because it will be too loose.

thanks amigo, I was gonna ask this on caimag, but it looks like the site must be down? I was wrestling with this about 11pm til midnight last night, I saw that long one and I thought that was the trick so I loosened that to no avail. guess I gotta loosen the others first eh. thanks much, I appreciate it.
my bike is almost all the way apart right now, rear chain, tins, wheels, brakes, oil tank/filter, all that stuff is off right now. gotta get this tranny figured out, seems to be locked up. I thought it was a shifter fork, but when I got the lid off those looked pretty staight.

imboden, affirm on the caimag site being down, as well as the shovelhead.us site...bummer.

Question on tranny. With the lid off you should be able to manually slide through the gears by turning them and sliding the forks into the corrcet position. If you can do that it is probably not a bent shifter fork. Has the tranny been apart, or the the cam in the lid?If so, you must use a Fork Shifter Gauge to check clearances on both sides of shifting clutches. When clearances are not equal and correct, shifting fork assemblies must be corrected by increasing or decreasing the number of shims between the shifter fork and shifter finger.
