Well who ever posted the fix for the bouncing tachometer 1996 750 Nighthawk was a great post!I just fixed my kids bike  had the problem. The top spring smaller than a dime,comes unsoldered from it's inside post that connects to the coil of the unit.After searching around for a couple of days,on the web I finally found the post here on this site.Believe it or not I was ready to send it Pennsylvania there's a place there called Powl's Tachometer been in business for 100 years!Was looking at $200-$300 to fix.Plus I'm on the west coast.Pretty tedious to solder what was wrong,but after 3 attempts I got it!!

I repaired mine a couple years ago, but sold the bike earlier this year. Here is my write-up on how to do it: https://www.jgaryward.com/wordpress/wp-content/uploads/2021/07/2TachFix.pdf

Wow, Just looked up Powl's since you mentioned it's in PA.  It's even close to me!

If mine dies, it would be worth $300 to me to have a pro do it if he promises it will be 100% after.

Just looking at busting into the tach in one of those ways is ugly. Then the delicate repair.
