    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.

I have removed the rubber blocks between the fins during re-build should I put them back? If so I would like to replace them with new rubber, where would I obtain theses. Do they go between every fin?
 
i believe these are for vibration.
not replacing these should cause you no noticeable problems.
if your want to replace these...they may still be available from suzuki.
 
Yes they are still available, and they cut down on the engine vibration hum at certain revs.
$1.65 each and there are 18 total.

If you use parts Outlaw, you can call them to discount the parts as there minimum item cost is now $2.49 each.

Part number, 11152-45000 or new number 11152-38A00

I thought they were to prevent harmonic vibrations from creating resonance in the engine and cracking parts.
 
are you serious??????????
Completely. It's the reason there are heavy/rubber dampers on belt-drives on cars.

http://en.wikipedia.org/wiki/Harmonic_damper

Though that's on the rotating part of the crankshaft, harmonics can still happen along the sides of the engine case.

And http://www.sciencedirect.com/science/article/pii/S0003682X13001576 Goes into detail about the purpose and end result of the dampers. Including a 10% increase in engine temp with the dampers. Without them, your engine may run cooler and less efficiently than it should.

Any time someone says they want to remove something, I like to ask them "So, you're smarter than the engineers? Why are they there in the first place?"

if the above rules applied there would never have been hot rods/drag bikes/land speed and so on..everyone would be "vanilla"
 
Those damper nubs are to keep the fins from ringing and radiating noise (in theory). A holdover from Suzuki's two stroke days. Not sure they do anything from a functional standpoint as judged in the real world. And not to worry about them affecting temperature, they don't enough to measure or matter.
