pulled stud

[bigun_78]

Hello Im new to the board and have a quick question. I recently purchased an XS1100 special from a local shop. I was riding it and all the sudden it started makin a horrible noise. After getting it home I inspected the headers and noticed one of the them to be loose. I tried to tighten it but to my dismay the stud pulled out of the head. Apperently the previaus owner had JB welded the stud into the head. I drilled out the JB weld and chased the previous threads, inserted a heli-coil but it still fit loosely. Any suggestions would be greatly appreciated

I think red Loctite might work to hold in the helicoil. Should fill in .003 of clearance.

thanx ill try that if the jb weld and heli-coil dosent hold

Or, just drill and tap for a larger size stud.

You could try a keensert. This is a solid metal tread insert that goes in much like the helicoil, but it had hooks or teeth that you set with a hammer and it holds real good!

I dont know if i can go to a much larger stud. Where can I find a keensert. Thanx for all the help.

Studs

On my xj, i removed all the stock studs bought some 3/8 threaded rod and drilled and tapped all the stud holes and installed 3/8 studs and double up on the nuts. I had to enlargen the flange holes a little but it worked fine. Why? you might wonder, cause 2 of the original ones were broke and the new ones are much stronger. Just thought i would mention it . $3.00 total cost and 3 hrs labour! HTH..............MITCH

I found them at one of my local hardware stores, but most of them do not carry keenserts. My hardware store called them threaded steel inserts. I did find that most any nut and bolt company or a company that deals in fasteners carry them. You can also do a search on the internet for keenserts and you will find plenty of them. Good luck!
