    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    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.

Bad Vibrations at 5000RPM+

Have you had the tensioner off?

I haven’t touched it. Is it the style of tensioner where you have to loosen it to let it take the slack out and then retighten, or should it be removing slack constantly?
 
It's self adjusting but someone might have locked it with the set screw. If so, download and read the manual and read the other stuff too . There's a lot on "Camchain tensioner in forum posts as well.... BikeCliff's Website ...Be sure to turn the engine in the correct direction(clockwise when looking at right side of bike) You can create slack turning the engine in the wrong direction...BUT indeed camchain should be much tighter than your (very nicely done) gif. Deflection should be very small when doing as you show..

UPDATE

Apologies for the long time between posts; I?ve been struggling to get parts delivered due to the ?rona.

So, I checked the valve clearances:The smallest feeler gauge money can buy wouldn?t fit. I ordered shims and waited for shipping. I also at this time ordered half moons and a new gasket; however, the replacement gasket was not only the wrong one, but was in pretty poor condition. After getting an OEM gasket from partzilla, and battling the cam end seals, the bike is back together.

First impressions:

The over all ride has improved dramatically. The bike is more responsive and the harsh secondary vibes are much less pronounced. I actually seem to have gained about 10mph in each gear at around 5000 RPM. I can cruise at 65mph at 4900. Even at the top end when the bike starts to vibrate the mirrors don?t fuzz up.

Going forward:
I think my next project will be throughly going over the carbs. I have serviced just about everything else so far. I was also interested in the Dynatek ignition if anyone has an advice when it comes to that type of thing.

Thanks so much to everyone who has helped out so far.
 
The stock electronic ignition on this bike is very reliable....so I?d skip the dyna for now.
Concentrate on the carbs....they need to be clean and balanced to each other - you want them all to be pulling equally especially as revs and loading climbs.

be sure to read and follow Nessism?s tutorial..... carb removal on this model is no fun ,so best to only have to do it once.
