I have a Dynatek 2000 ignition in my bike, which shows TDC for cylinders 1+4 as well as 2+3. Which TDC do I use to set the cams to?

1 and 4 is the correct mark -
Thanks! Is it one of those standard things? Is it always cylinder one that you set at TDC or is it just 1+4 on GSs?Comment

Unless otherwise stated, #1 seems to be the standard.

1 or 4..ON THE COMPRESSION stroke. Unsure or cant "feel" the compression by puttingb your finger over the plug hole? Then just out a compression tester in number 4 ( since you turn the crank from then right side of the bike ) and watch it as you turn the engine over. The needle will move on the compression stroke. Remove the guage and continue bringing the piston up using a dowel or something to visually see it coming up. Go slowly and just as the dowel stops coming up then check the timing mark and set it exactly. Replace the cams per the numbers on them set as the manual shows and youll be good to go.MY BIKES..1977 GS 750 B, 1978 GS 1000 C (X2)

I would rather trust my bike to a "QUACK" that KNOWS how to fix it rather than a book worm that THINKS HE KNOWS how to fix it.Comment

Actually, until you install the cam, 1&4 have no idea which one is on the compression stroke.Originally posted by chuck hahn View Post
They just go up and down together, the cam will determine whether it's compression or exhaust when they go up.

So as long as I have 1+4 at TDC I am good to go? Cool - thanks!Comment

You can get a service manual off basscliff's site. What you seek is within. The 1100G engine is almost identical to the 1000. Please do some homework or you might mess something up.Ed

Actually I have a manual. I follow it religiously when putting the engine together! BUT - the original ignition was different and had different markings. I have made it more challenging by using a Dyna 2000 ignition which has markings for TDC on both 1+4 and 2+3.Comment
