    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.

My 1100 would ping in high gear @ low rpms. Keeping the revs up would prevent the problem but it still didn't seem quite right. Valve settings good, timing good, tried colder plugs, etc... The carb boots looked pretty good but I decided to change them anyhow because nothing else was helping. I was surprized to find the o-rings between the head and boots had literally disintegrated (bike only has 15K on it). New o-rings/boots and NO more pinging at any Rpm :)
 
That's right. Though sometimes the ignition timing is off, a lean mixture due to an air intake leak will cause pinging. Always apply some hi-temp bearing grease to the o-rings to help them last and don't overtorque the o-rings. 6 ft/lb torque is good. Good tip.
 
Hey Guys
Please tell me what O rings are we talking about, as I have experienced much the same problem. Although only at low RPM. any help will be great.

The intake manifolds have an o-ring to seal between the head and themselves. The intake manifolds are between the carbs and head. If the o-ring or manifold is damaged, it will allow air to get in and you will have a lean condition that will increase the rpm's. At first, the bike will idle OK at start up, but once warmed up, the rpm's increase. If you turn down the idle, the next time you try to cold start it, the idle will be too low.
 
Archie, if you have a 16 valve motor you don't have these o-rings - you have rubber manifolds held on with hose clamps. You will see the same symptoms when the rubber manifolds are cracked, the clamps are not tight, or the rubber manifolds are just stretched due to age.

Do you have a 8 valve or 16 valve motor?

A sub-tip:

I traced boot leaks with silicon lube. I would spray each section I wanted to test as the bike ran. The silicon temporarily sealed pinholes and leaks, causing the bike to react appropriately.

Once I identified the leak, fixing it was easy. And bonus: the silicone blackened up the boots, and softened them back up, as they were starting to harden.

I used a non-conducting silicon spray that I use in the cables and controls.
