    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...

    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.

A well sealed air box

I have an 81 850L. The smallest things on these bikes make an amazing difference. My boots for my airbox were on half a$$ed and I thought that was good enough. I managed to coax them back on tightly and they seem to be completely sealed. I installed a new air filter and sealed my airbox off completely with some weatherstripping. Holy crap what a different bike. Pulls good at all rpms like NEVER before. Reading all your good advice on this site has really helped me troubleshoot with success!! Next is the intake boots and o rings, valve adjustment and possibly an electrical upgrade. Just thought you guys would want to know, thats all.

Having gone through the same situation, you can't stress enough, how important air flow (or limit the excess flow) makes a night and day difference on these bikes. :?

Great to hear that your bike is running much better. Thanks for the feedback. There are many here who seek advise and never bother to feedback their results.
It might now be prudent to do some plug reads to confirm your carb tuning is right.

Especially on the 850's it seems!
 
Great to hear things keep getting better. Did the sealing the air flow affect the starting & idleing?
 
Nice work!

Nice work!

Mr. hartlygs,

Good going! Sealing the airbox was the very first bit of maintenance I did to my bike when I got it home. Since then I've learned how to change the oil, installed a new deflector windshield, changed differential oil and bevel gear oil, put on new tires, bled the brakes, adjusted the valves, cleaned up the electrical connections, replaced the tach seal, and changed the plugs. Next on my list is installing Progressive fork springs. I have them, but ran out of time today after adjusting valves and bleeding brakes (pictures coming soon).

This is a great bunch of folks here who have taught me how to be a better motorcycle mechanic and a better motorcycle rider.

Mr. hartlygs, do you have a manual? If not, PM and I'll see what I can do.

Thank you for your indulgence,

BassCliff
