    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...

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.

I'd like to replace the 18 valve cover bolts with stainless allen heads.
Anyone know the bolt specs off hand?
Have a supplier, 9 cents/bolt in 50 count pack minimum
 
First of all, your '81 should have 16 bolts, not 18. :-\\\

I just looked at a parts fiche, it says 18. I also looked at my '80 850 (same basic bike), it only has 16 bolts.

Next, look at a parts fiche, you will see that the part number for those bolts is 01550-06407.
Look right after the hyphen, it is telling you that it is an M6x40 bolt.

That size reference works for virtually every piece of hardware on the bike.

Thank you Steve for the info, appreciated!
I was going by the parts fiche in reference to the bolt count/number, hadn't actually looked at my bike.
 
There are four M6X25 bolts for the breather cover as well, but it's best to leave these as normal bolt heads so you can reach them from the sides with a wrench -- if you replace them with allen heads, it's hard to reach them from the top.

Unless the engine or cylinder head has been transplanted from a late '82 or '83 model, there should be 16 bolts. Either way, you'll have plenty if you have a box of 50. :D
