Cant find TDC

[Guest]

I just replaced the block, head, and now im trying to install the cams. Problem is, I cant find TDC. The bike is a gs750 1979, and the PO installed a Dyna S ignition (Sweet! didnt know that when I bought it).

there is no mark on the engine case. I can find one anywhere.

Is the Dyna S missing a plate or did the PO lose a part?

Hopefully I'm just being dumb.

See that round hole in the Dyna-S plate below the top center retainer screw, near the top of the left hand #1-4 module hex head screw. The marks are under that hole, on the advance mechanism. There should also be a bracket behind the module plate held by the three retainer screws with a pointer marker on it. http://www.mtsac.edu/~cliff/storage/...arly8valve.pdf

This is from the 550 manual, but should be about the same. Note that the fixed timing mark is on a plate that had to be transferred with the Dyna S:

Plate was not transferred. I just have the mechanism with the 1-4 T and 2-3 T marks. No plate with reference marks.

Could I come close by lining it up to the top screw hole? At least close enought to put my engine back together and then time it when the plate comes in? (If i can get one)

It's called a timing plate, BikeBandit sells it for under $6.00, so they are available from any Suzuki dealer or parts outlet.

Right on. My dealer is good people. I will try and pick one up tomorrow. Thanks for all the help.
