Heli coil or time sert on Harley exhaust stud. Sorry off base a little.

[2ndgear]

What I have is a shovel head harley with the 5/16 exhaust stud hole stripped out. I believe there is enough material there to install a heli coil but not sure if a time sert would work do to maybe not enough material there to drill and tap. I know a key sert is to big on the OD to work. My question is what is the out side diameter of the drill for the time sert. Or is there any thing else that would work? Thanks in advance.

Frt or rear head? I found that the best way is to get it TIG welded and redrill and tap or add a time sert. It can be bilt up on the outer edge to avoid being too thin. I own 2 shovels so experience counts!

Thanks GJCAT427

It is the front head. I plan on putting a few a few passes over the out side of the exhaust port. I am going to do the front and the rear head at the same time. This is on a 1979 lowrider and I do have enough room to do it with the heads on the bike. Where is a good place to buy the time serts. I feel they will do a much better and stronger job then the heli coils will. Thanks
