It is not my bike and I'm told it needs a clutch. Meanwhile our Odyssey has had a massive brake shudder for months, the Miata runs rough and smells bad, and last night the Accord started spurting brake juice and winking the idiot light. I may tell my friend to find a trailer and drag the hawg out of here any way he likes. His clutch-guy can surely do-up the battery.
As romantic an idea as it is to take it on yourself, I've been sent by your doctor to tell you to run the other way...
All motorcycle maintenance/repair is frustrating due to the lack of space. As Jack mentioned, you have 2 options: work uncomfortably or work uncomfortably.
Just take the seat off to get to the battery, then just take the pipes (don't snap a stud!) and the case apart to "check" the kickstart...then notice the brake lines are "aged" and the wiring is "questionable"...etc. X 100
With all older mechanical repair jobs there is always an issue that arises that makes the "mechanic" look like the bad guy, and the sooner you get out of that position the healthier your friendship can stay.
Don't let the balmy temps and the sunshine and the look in his eye sway your decision...he'll be ok.
Owning a '77 comes with the responsibility of upkeep.
Find a "local" cycle guru who will get some pleasure out of breathing life back into her (only problem is, this time of year brings out all of the bike neglectors...so he'll have to get in line)
Save your back for the important things in life like putting a cat in a Miata or trading it out for more debt.
I see nicer bikes being parted out for more money.
I also see "not too old" guys walking around hunched over because they tried to help out a friend X 100
I know you know ALL of this, and it sounds like you were talking yourself out of it. I'm just here to confirm that action.
