I'd like opinions on whether I should repair or replace my cases:
I stripped a cylinder stud thread in my crank case and my local dealer told me to use a helicoil to fix it. That didnt hold and it left a huge hole when I pulled it out and also weakened the metal. So then I tried an oversize timesert (shoulda used that first from what people are telling me now) but by then the intial hole was too big and the tap that comes with the kit didn't leave enough thread to hold so it pulled out too. Now I'm debating on whether to just replace my cases ($1800) or have the one hole drilled out from the inside of the case, welded/filled back in and then tapped again ($400). I'm waiting to hear back from S&S on the proper tap size and welding rod alloy so if I go that route it doesn't fail again in 1000 miles. Half the people I talk to say to weld it and the other half tell me the heat would F up the case and possibly crack around the weld sometime down the line.....
What should I do?
