It's dingaling'n time
For some time now I've been working on my engine tear down to clean and prep for paint. Everything has gone very smoothy and my parts are all labelled and sitting in little baggies all over my house (standard operating procedure).
UNTIL...
...a while back I had a bit of trouble removing screws that were fastening brackets surrounding the gear shift drum. One was quite easy, the others have caused me lots of stress. I was mortified to discover that Yamaha made their panhead screws not out of steel but rather a hybrid of squishy metal and cookie dough! 4/5 screws stripped.
Fast forward to me and a bolt extractor kit: 2 out of the 4 stripped screws are now extracted (screws ruined). This leaves me with 2 more to go. One of them extracts halfway before the thread unravels (it was crazy) and the head broke off. The other broke 2 extractor bits, one inside the drilled out screw and one in the head. Even my uncles industrial drill press couldn't help me, and now I have a completely pooched screw that holds a bracket.
I've tried everything I can think of and held off asking for as long as possible, but I have finally run out of ideas. What can I do? Will the brackets be fine -1 screw? Should I JB weld the tap solid and retap it?
tldr; I have an extremely messed up tap in my engine block, what should I do to fix it/do i need it?
Edit: Stripped thread is part number 19 on the OEM parts catalogue for the shift drum. I'll post up some photos after work
