stripped thread at fuel pump repair quesiton

[kotkinjs1]

In the ongoing saga of the 82 gl1100 that's nickel and diming me with issue after issue, I've now got an oil leak under the right head/valve cover. I'm 99% positive I've nailed it down to the thick gasket area between the fuel pump and the head due to a stripped bolt I realized it has. It's the inner bolt. I've asked elsewhere and the best repair seems to be the helicoil route. I've pretty gotten over my anxiety about drilling into the head but I've got one more question before I begin....

I'm not sure of the 'geometry' for lack of a better word of the relationship between the tach cable, the blind hole (I guess it's a blind hole?) into the cylinder head, and what happens when I enlarge that hole to be able to insert the helicoil in relationship to the tach cable. Will I mess anything up? Will the tach cable still be secured by that bolt when it's in there and the helicoil won't be in the way? Is there any other way around this issue (the tach cable being secured into that bolt hole) by using another thread repair method other than an insert?

p.s. - I think I've got the sprague clutch issue fixed with the Seafoam recommendations. I'm about 75% through my first 100 miles and it pretty much starts right up, even after not touching it for a couple weeks over the holidays. Thanks guys!!

use the proper size drill, sometimes that comes with the Helicoils also.

do NOT drill any deeper than the existing threads go.

and the Helicoils often come with their own thread sealer to keep them from backing out.

Once repaired, every thing should work as before

Got it done and was a lot easier than use worried about! Super simple actually. Thanks! So far no leak.... Will take it on a longer ride tomorrow (in the daytime lol).
