    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 a 82' gs1100gl (2) valve engine.
Removing current electronic ignition and installing a Dyna 2000.
WHERE is the TDC mark on this engine???
thanks
 
I believe it is the same as my GS1000G
under the points cover(right side of engine) there should be 3 marks, "T" "1-4" "2-3"all these can be seen through the small hole above the points/pick-up plate.

"1-4" will be your tdc mark you are lookin for, gl and let us know how it works out :)
 
My 82' had electronic ignition. So, no points plate. There are 1-4 and 2-3 marks on the OEM rotor which gets removed durning installation. Those marks were a timing REFRENCE to each 1-4 and 2-3 signal generators and is not relevant to Dyna.
What is needed is a "FIXED" TDC mark on the engine case, (right side) to set the new Dyna marked rotor to. The new rotor has a degree scale printed on it. But without a fixed TDC mark on the engine the timing marks have nothing to align to.

The mark is on the gold colored plate mounted behind the plate the stock sensors were on
 
Re: Dyna Sure?

For installing the Dyna 2000 system, you neither need nor use a TDC mark.
Set the degreed Dyna rotor to align at 32 degrees of advance with the 32 degree advance line centered on the 12 oclock position breaker plate mounting bolt. Switch the control unit to the test function and rotate the breaker plate to get a plug to fire on this mark.
If you set the breaker plate so that its mounting screws are centered in the slots, you should be VERY close to firing at 32 deg. Set the advance curve to #1 when static timing is completed. Do not move the pickups from their factory set position on the breakerplate. You will find that it is only necessary to time either pair of cylinders. The remaining two cylinders will be dead on.

Thank you daveo and earlfor.
I just installed it and took it for a ride. MUCH smoother through the full RPM range. Exhaust is quiter, especially on throttle off. Lot less "rumbling".
was a good investment/upgrade even for a working ignition system.
 
Yep, I know I am really happy with my Dyna2000 on the 1150. :-) :-) :-)
