QuestionQUESTION: My '94 bagger has 103k miles on it. My primary drain plug won't seal properly after numerous services. I want to install a heli coil insert. My question is it 1/8 npt. If not, what thread pitch is it.
Thanks for your time, Greg Selky
ANSWER: I wouln not install a heli-coil. They dont work very well on bolts that you are taking in and out alot. use a stainless steel insert, which will not pull out. Its a 1/8-27 NPT
Good luck and happy riding

QUESTION: Mike,
Thanks again for your time, and replying quickly. I've used heli coils in the past, and have had good luck with them. However; not in this application, drain plug. What type of ss insert would you recommend? What's it's brand name,and is there a generic that's just as good and cheaper? I've used inserts in the past, but on the primary the one's I used would be too long.They would be way thicker than than the primary case, and hit the chain.
Thanks, Greg Selky
AnswerI use the lock type so they dont come out. I have gotten them at grainger before. I did some checking and you have to buy 25 inserts and you have to have a special too to install them. You might want to look around on the net and see if you can find some where you dont have to buy so many
Good luck and happy riding
