The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Drain plug hole STRIPPED!!!

Isn't helicoil a bit long? This would mean you'd be draining the oil and the deposits would stay in the bottom of the pan?
 
I wouldn't use a heilcoil, they tend to unscrew when you take the bolt out. A Timesert insert is far better for things like spark plugs and drain plugs because they lock in place more secure than a helicoil.

That said, to repair the striped threads there are oversize drain plugs for just such a purpose. They are self tapping; you just torque them in. Napa sells them and a number of members here have reported positive results using them.

Good luck.


I have had some success with the helicoil system. Mine had a helicoil repair in the oil drain years ago with no problems. It was installed by my favorite and trusted dealership to repair the damage caused by a hamfisted mechanic (me). :o
 
I know the thread in a GS850 oil pan is the same as a spark plug, 14mm X 1.25mm, so inserts are very easy to find.

I installed a solid insert from McMaster-Carr when I rebuilt my GS850 engine. I like knowing the threads are solid steel.
 
I don't know if they are the same but I have a pan with a drain plug for a 1981 GS750L in my shed. You're welcome to it if it will help.
