    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. 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.

Took the valve cover off the adjust the valves, and just because I checked the tightness of the 4 cam bearing caps that bolt over the cams.....some of them are stripped out....thinking the only fix is to drill and tap for larger bolts unless someone has an easier fix...like fill it with JB weld and bottom the bolt out in it.

Guys I really appreciate your help, knowledge and patience with us new guys if really gives us the confidence to dive into these machines and work on them instead of making the bike shops money

Once I have this one up & running right I have a 66 Honda Dream to rebuild....

A simple method, and one which does not require much material loss, is to use a threaded insert, which is screwed directly into the head material. They are called helicoils. You put them in as per instructions, then use the old bolts.


How to do it:

Sorry to hear about this problem. Timesert or helicoil is the proper way to repair the threads. Unfortunately, you are most likely going to have to pull the head to do the job right; it's important to drill and tap the holes at a 90 degree angle so using a drill press is strong recommended.

Good luck.
 
Timeserts are the best way to go for a proper repair. Helicoils work as well, but Timeserts are better as they are a solid material instead of a spring coil. That being said, my toolbox in the garage has MANY helicoils in it for repairs... You can get Timeserts from places like McMaster-Carr pretty cheaply.
 
There is also a (slim) chance that there are some unused threads at the bottom of the holes, so longer bolts might work, too. I would not go much longer than 5mm, but that's not much thread area to hold something as important as cams. Use a piece of wire to measure how deep the hole is, you might be able to use bolts 10mm longer.

If that does not work, Heli-Coil or TimeSerts. Heli-Coils are sometimes available at your better auto parts stores, too.

I'll se if I can find a longer bolt for it, time-serts do seam like a better product as it seams they tried heli coils and they did not hold.....possibly improperly installed.
 
Welcome to GSR.

Very similar to my expereince with my bike I got 2 years ago (and same reaction relative to the PO). Only I found the cap bolts broke off. And more broke when I tried to turn them out.

I took head to machine shop where they drilled them out or used easy out. On Two of the bolt holes they had to use the helicoils. And I think one of them maybe be loose now. So that alternative mentioned above has my interest.
