    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.

Dwell meter/Tach recomendations?

I'd like to verify the electronic tach on my 1100ES is accurate. It's been floating pretty badly past 8k rpm and want to see how bad its off even in the low ranges.

Any recommendations for budget minded digital automotive multimeter or other tool?

Dunno if this helps you or not but I'm planning on picking one of these up on Tuesday:

When I fire my 450 up again in a couple of weeks I need the dwell angle function to see if my home made ignition module is working right or not.

My only concern is if the wasted spark confuses the meter, so I'm half expecting to have to divide by two if it's not set to compensate for the wasted spark...
 
If you have a GPS you can calculate RPM at some given speed and then go take a ride to verify. Mention GPS because you can't trust your factory speedo either. I can help you with the calculation if necessary. Key thing is to measure the wheel radius accurately with the riders weight on the bike. You can also measure circumference which may be easier.
