1. Tensioner question. One from 78, one from 79. Both seem to be in good condition. Should I favor one over other?

2. Seals question. For shift rod Do the installed same orientation, face out? Or they installed back to back?

#1 use the tensioer with the stronger spring. Maybe a manual tensioner mod would be an option..
#2 do install the seal in the same orientation and use a good permanent grease on the shaft agianst wear, moisture and corrosion.

For #1 I'd rather not spend money yet if not needed. Is there issue with stock tensioner(s)? Bike is stock, not for racing.

For #2. What was an idea for 2 seals? You propose I do it like pictured (dang I didn't pay attention when disassembled). But to me sounds like #2 should be reversed. This way I can pack it with grease inside. No?

#1 you don´t need to spend money for the manual tensioner mod only some work to do by your self, pics follows...
#2 as you sketch up, position the seal like that to keep the grease into the shaft bore of the clutch case.

Problem is - "INSIDE" is not sealed. It's a void where sprocket/etc is. To me makes sense to keep grease between seals.

If you decide on the 78 tensioner get a new nos spring on ebay for it............ BIG diff in tension.
